Michael A. Barnhart, Can You Beat Churchill? Teaching History through Simulations (Cornell University Press, 2021).

How do you get students to engage in a historical episode or era? How do you bring the immediacy and contingency of history to life? Michael A. Barnhart shares the secret to his award-winning success in the classroom with Can You Beat Churchill?, which encourages role-playing for immersive teaching and learning. Combating the declining enrollment in humanities classes, this innovative approach reminds us how critical learning skills are transmitted to students: by reactivating their curiosity and problem-solving abilities.

Barnhart provides advice and procedures, both for the use of off-the-shelf commercial simulations and for the instructor who wishes to custom design a simulation from scratch. These reenactments allow students to step into the past, requiring them to think and act in ways historical figures might have. Students must make crucial or dramatic decisions, though these decisions need not align with the historical record. In doing so, they learn, through action and strategic consideration, the impact of real individuals and groups of people on the course of history. 

There is a quiet revolution underway in how history is taught to undergraduates. Can You Beat Churchill? hopes to make it a noisy one.

Rebecca Beigel and Julia Schuetze, Cybersecurity Exercises for Policy Work: Exploring the Potential of Cybersecurity Exercises as an Instrument for Cybersecurity Policy Work (Stiftung Neue Verantwortung, April 2021).

Malicious cyber activities are increasing worldwide and getting increasingly more sophisticated. Individuals, businesses, and governments explore different ways of tackling this development, for example, through developing policies to counter or mitigate cyber threats. One promising instrument for doing so is cybersecurity ex- ercises. Different cybersecurity exercises (e.g., red team/blue team exercises, cyber wargames, workshops, tabletop exercises, and simulations) can address different audiences and goals – from examining technical responses by critical infrastruc- ture providers to assessing diplomatic responses to a cyber incident. To grasp the potential of cybersecurity exercises – particularly for policy work – it is important to explore the different types of exercises in more detail.

The paper first highlights defining features of each cybersecurity exercise type to emphasize each type’s advantages. Workshops, for example, are speculative, collab- orative, and can improve understanding between different actors. Meanwhile, simu- lations can replicate reality as much as possible using digital networks, which helps simulate attacks and the reactions to such attacks. Secondly, the different exercise types are applied to different stages of the policy cycle – a cycle mapping policy work from defining a problem to the implementation and evaluation of a policy – to explore reasons for using them at certain stages of policy work. Simulations, for ex- ample, are particularly beneficial to use when implementing or evaluating a policy, for example, for testing its effectiveness.

The paper creates a simple guide for exploring the potential application of cyberse- curity exercises for policy work and for strategically using them. It is recommended to go through a three-step process to find whether cybersecurity exercises are an instrument to be used for a specific policy objective.

1) Firstly, scope out the policy work – consider the policy work at hand and the target audience to be reached.

2) Secondly, identify the stage of use – identify where the policy work is best situat- ed on the policy cycle.

3) Thirdly, consider the defining features of cybersecurity exercise types and identify which exercise type is the best to achieve the policy work goal.

Ultimately, the paper highlights that cybersecurity exercises are an instrument that decision-makers should consider when developing cybersecurity policies and/or aiming to achieve different cybersecurity policy goals. 

Arvid Bell and Alexander Bollfrass, “To Hell with the Cell: The Case for Immersive Statecraft Education,” International Studies Perspectives (June 2021).

Current wargaming techniques are effective training and research instruments for military scenarios with fixed tools and boundaries on the problem. Control cells composed of officiants adjudicating and evaluating moves enforce these boundaries. Real-world crises, however, unfold in several dimensions in a chaotic context, a condition requiring decision-making under deep uncertainty. In this article, we assess how pedagogical exercises can be designed to effectively capture this level of complexity and describe a new framework for developing deeply immersive exercises. We propose a method for designing crisis environments that are dynamic, deep, and decentralized (3D). These obviate the need for a control cell and enhance the usefulness of exercises in preparing military and policy practitioners by better replicating real-world decision-making dynamics. This paper presents the application of this 3D method, which integrates findings from wargame and negotiation simulation design into immersive crisis exercises. We share observations from the research, design, and execution of “Red Horizon,” an immersive crisis exercise held three times at Harvard University with senior civilian and military participants from multiple countries. It further explores connections to contemporary trends in international relations scholarship.

William DeBerry et al, “The wargame commodity course of action automated analysis method,”  Journal of Defense Modeling and Simulation: Applications, Methodology, Technology (2021).

his research presents the wargaming commodity course of action automated analysis method (WCCAAM) – a novel approach to assist wargame commanders in developing and analyzing courses of action (COAs) through semi-automation of the military decision making process (MDMP). MDMP is a seven-step iterative method that commanders and mission partners follow to build an operational course of action to achieve strategic objectives. MDMP requires time, resources, and coordination – all competing items the commander weighs to make the optimal decision. WCCAAM receives the MDMP’s Mission Analysis phase as input, converts the wargame into a directed graph, processes a multi-commodity flow algorithm on the nodes and edges, where the commodities represent units, and the nodes represent blue bases and red threats, and then programmatically processes the MDMP steps to output the recommended COA. To demonstrate its use, a military scenario developed in the Advanced Framework for Simulation, Integration, and Modeling (AFSIM) processes the various factors through WCCAAM and produces an optimal, minimal risk COA.

Pia Henning, “‘Game on!’ A research project on the Prussian Kriegsspiel,British Journal for Military History 7, 2 (2021).

The Prussian Kriegsspiel was the very first professional wargame and was originally introduced in the Prussian army in 1824 but has so far seen very little systematic research. This research project has compiled a corpus from all the rulesets currently extant, which was then made subject to formal and linguistic analysis. This yielded results in three important areas: First, by comparing them with a collection of contemporary texts on military theory it was possible to identify Kriegsspiel rulesets as distinctive text types. Second, comparing the rulesets gave valuable insights into the developmental history of the Kriegsspiel. And finally, it was possible to distinguish three distinctive phases in the development of the Kriegsspiel.

Mary Ann Hopper, “From Lessons Learned to Improvements Implemented: Some Roles for Gaming in Cybersecurity Risk Management,” in Advances in Cybersecurity Management (Springer, 2021)

Effective cybersecurity risk management hinges on a strategic blend of people, processes, and technology working together to recognize and prevent attacks; mitigate and minimize negative impacts should attacks succeed; and resume operations after recovery. Ideally, risk management involves processes that engage the entire organization continually and holistically—not just episodic reactions by a few key personnel in times of crisis. The translation of lessons learned into implemented and validated improvements may be a missing or underutilized best practice. This chapter explores ways gaming can be used as a complement to authoritative standards and frameworks to optimize an organization’s cybersecurity posture and preparedness. A variety of gamified approaches are described and presented as useful tools with differentiating value at multiple stages in an ongoing cybersecurity risk management cycle. State-of-the-practice exemplars and successes are cited as are approaches to adapting games to both assess and improve an organization’s cybersecurity posture. The chapter concludes with some speculations about how games focused on cybersecurity can be expected to evolve and gain greater traction for risk management in light of emergent technologies and increasingly complex threat and defense landscapes.

Bong Seok Kim , Bong Wan Choi , Chong Su Kim, “Methodology of battle damage assessment in the naval wargame model – Forcusing on damage assessment of warship,” Journal of KOSSE 17, 1 (2021). [In Korean]

Wargame is a simulated military operation with certain rules, specifications, and procedures, in which soldiers can virtually and indirectly experience the war. The ROK Navy operates the Cheonghae model, a training wargame model for helping commanders and staff master the procedures for conducting the war. It is important for commanders, staff and analysts to know whether a warship can perform its missions and how long it can last during a war. In existing model, the Cheonghae, the probability of kill of a warship is calculated simply considering the number of tonnage without any stochastic elements, and the warship’s mission availability is also determined based on predetermined values. With this model, it is difficult to get a value of the probability of kill that makes sense. In this dissertation, the author has developed a probabilistic model in which the warship vulnerability data of ROK-JMEM can be used. A conceptual model and methodology that can evaluate the mission performance of personnel, equipment, and supplies has been proposed. This can be expanded to a comprehensive assessment of wartime warship loss rates by integrating damage rates for personnel, equipment, and supplies in wartime.

Nina Kollars and Benjamin Schechter, Pathologies of Obfuscation: Nobody Understands Cyber Operations or Wargaming, Atlantic Council, February 2021. 

National security and defense professionals have long utilized wargames to better understand hypothetical conflict scenarios. With conflict in the cyber domain becoming a more prominent piece in wargames in the national security community, this issue brief seeks to identify the common pathologies, or potential pitfalls, of cyber wargaming. It argues that the inherent turbulence of the cyber domain and segmented knowledge about cyber weapons negatively affect three components of cyber wargaming: the scenario development, the data usability, and the cross-participant comprehensibility. The brief offers some initial solutions to these problems, but, ultimately, the purpose of identifying pathologies is to prepare designers to meet these challenges in each unique design.  

Xuan Liu et al, Tactical Intention Recognition in Wargame, IEEE 6th International Conference on Computer and Communication Systems (2021).

Opponent modeling is a significant method in imperfect information games. And intention recognition is regarded as the important but difficult in opponent modeling. This paper focuses on the task of tactical intention recognition in computational wargame. We propose an approach to recognize opponents’ intention which models the intention as long-term trajectories. The approach consists of situation encoding model and position prediction model. The first model uses attention mechanism to attach the statistic map data with dynamic feature and adopt CNN to learn the representation of battlefield situation. The position prediction model then predicts the long-term trajectories of opponents, based on well-represented situation vectors. Experiment indicates that our approach is proven to be effective on the task of tactical intention recognition in wargame. Meanwhile, a high-quality replay data set for analyzing the actions’ characteristics is also provided in this paper.

Jon-Wyatt Matlack, “Operation Barbarossa 2021: Practices (Re)Rendering the Myth Of The ‘Clean’ Wehrmacht In Contemporary Grand Strategy Computer Gaming,” Europe and America in the Modern World blog, 28 July 2021.

ScienceCampus doctoral researcher Jon-Wyatt Matlack explores the significance of computer games in shaping imaginations of the past. Focusing on Hearts of Iron IV, he considers how the format can encourage revision of the Nazi past, going against the grain of efforts towards critical Vergangenheitsbewältigung, or working through the past. The article explores how gamers can take up positions perpetuating the myth of a clean Wehrmacht while perpetuating narratives of a barbarian Eastern Europe where the USSR poses the greatest threat to humanity. He shows how reconstructions of historical narratives in digital spaces deserve more critical interrogation as a medium for the production of counterfactual history, especially given how popular and successful they are as depictions of the past, albeit a counterfactual one that draws on players’ affective urges and distorts historical reality.

Miles Paca et al, “Tactical Nuclear Wargaming: An Innovative Approach to Conventional Nuclear Integration Techniques,” C􏰀􏰁􏰂􏰃􏰄􏰅􏰆ountering WMD Journal􏰀􏰁􏰅􏰂􏰈􏰉  22 (2021). 

The current requirements for CWMD preparedness across all levels of the Joint Forc- es have led to focused initiatives in the realm of nuclear weapons defense planning, training and exercise1. Techniques like military wargaming for putting such initiatives into action are of critical importance to addressing the centralized concepts of nuclear defense and deterrence. Conventional Nuclear Integration (CNI), a concept referring to the side- by-side operation of nuclear and conventional forces referenced by Kinman2, is a field of nuclear defense strategy that includes nuclear weapons employment on the battlefield. Though not always expressly grouped under the umbrella of CNI, military wargame ex- ercises which could be considered within the subset of CNI have provided insights into operations on the nuclear battlefield since the Cold War era.

Roderick Parkes and Mark McQuay, The Use of Games in Strategic Foresight, DGAP Policy Brief (July 2021).

After a decade of crisis, the EU now routinely uses futures meth- ods to anticipate the unexpected. Its aim is to address its blind spots. This paper details our experience of designing a foresight exercise to help EU diplomats face up to one of the most ingrained types of blind spot: a taboo issue. But our experience showed instead the dangers of such exercises. Far from needing encour- agement to address a taboo, our target audience wanted an excuse to do so, reflecting a shift to a more “geopolitical EU.”

Strategic foresight exercises are designed to help participants recognize their cognitive biases. But the more policymakers adopt them as routine, the more they use them to reinforce their existing aims. Simply: they learn to manipulate outcomes.

To prevent cheating, experts introduced adversarial elements, where colleagues paired off against one another. Competition was meant to inject new thinking into policy and break up bureaucratic hierarchies. In fact, these too reinforced old biases.

Table-top exercises (TTXs) are now the go-to tool, adopted by the EU: rather than competing, participants play as a single team. Collaboration encourages the kind of “risky- shifty” behavior which policymakers need in order to drop old shibboleths.

Alicia Ruvinsky et al, An Approach to Gamifying Acquisitions for Assessing Impact on Military Strategy of Nation States, IEEE Conference on Cognitive and Computational Aspects of Situation Management (CogSIMA) (2021).

Complex Systems in which humans play a role, namely Human-Integrated Complex Systems (HICS), can be difficult to model or simulate due to the uncertainty introduced by the human component. Traditional modeling approaches such as physics-based modeling do not provide predictive insight towards situation awareness and management. War game designers, and game architects are familiar with HICS problem spaces, and use gamification of such complex contexts as a means of modeling human behavior to inform, predict, and manage an HICS style problem. The game play thereby becomes a means of providing situation awareness and management of the HICS by using human action during game play as a heuristic for pruning the intractable possibility space of the problem at large into a likely probability subspace based on the actions players actually take when playing an HICS game simulation. This paper explores the approach of gamification of real-world HICS problem spaces for situation awareness and management. A gamification methodology is introduced and investigated through the use case of military acquisitions.

Peng Sun, Jian Zhang, and Ling-hui Wang, “The Application Study on Accurately Search&Rescue of the Wounded on the land battlefield base on ‘Beidou+ Armored ambulance’“, 2021 International Conference on Mechanics and Civil, Hydraulic Engineering.

The accurately program of search&rescue of the wounded is designed and an initial design idea of various subsystems is proposed in order to provide theoretical explorations and solutions for making the search & rescue of the wounded on a land battlefield immediate, intelligent and accurate and for lowering the death and disability rates of the wounded. A full combination of skill features and functional advantages is made between BDS and Armored ambulance, which is systematically applied to the search & rescue on the land battlefield. The rationality and feasibility of the program of search&rescue are guaranteed by functional combinations, comprehensive integration and experimental verification. The verification of the program of search&rescue is made in the form of war-game exercises. The result finds that the “BDS + Armored ambulance” pattern of search & rescue can accurately acquire real-time locations of the wounded, immediately provide on-site first-aid services and emergency aid & treatment for the wounded and rapidly receive and transfer the wounded, which demonstrate a better practice and application prospect of health services. As the BDS-3 is to be put into service in 2020, the informationized upgrading and transformation of Armored ambulance will be gradually completed and the “BDS+ Armored ambulance” program of search &rescue will exert a more obvious influence on the search & rescue of the wounded on the land battlefield, which provide a capability support for realizing the idea of “Medical Treatment be with Soldiers”.

Ben Taylor, COVID-35: A game of pandemic management, Defence Research and Development Canada DRDC-RDDC-2021-D042

The Simon Fraser University Faculty of Health Sciences ran course HSCI 486—Global Perspectives on the coronavirus disease 2019 (COVID-19) Pandemic—for fourth year undergraduates in the fall of 2020. The course instructors designed the course to culminate in a class game to expose undergraduate students to a complex public health decision-making environment. A game was developed by the author in consultation with the class instructors to allow teams of students to make policy decisions as the governments of neighbouring countries facing a pandemic similar in nature to COVID-19. The game was set on a fictional continent with fictional countries which nevertheless shared some characteristics of certain real countries. The game was supported by a spreadsheet model to evaluate player decisions, which was kept as simple as possible to create believable behaviours without seeking to be an accurate simulation. The game was successfully run in a 3-hour class and received very positive feedback from both students and instructors.

Dillon Tryhorn, Exploring Fog of War Concepts in Wargame Scenarios, Air Force Institute of Technology Theses and Dissertations (March 2021).

This thesis explores fog of war concepts through three submitted journal articles. The Department of Defense and U.S. Air Force are attempting to analyze war sce- narios to aid the decision-making process; fog modeling improves realism in these wargame scenarios. The first article “Navigating an Enemy Contested Area with a Parallel Search Algorithm” [1] investigates a parallel algorithm’s speedup, compared to the sequential implementation, with varying map configurations in a tile-based wargame. The parallel speedup tends to exceed 50 but in certain situations. The sequential algorithm outperforms it depending on the configuration of enemy loca- tion and amount on the map. The second article “Modeling Fog of War Effects in AFSIM” [2] introduces the Fog Analysis Tool (FAT) for the Advanced Framework for Simulation, Integration, and Modeling (AFSIM) to introduce and manipulate fog in wargame scenarios. FAT integrates into AFSIM version 2.7.0 and scenario results ver- ify the tool’s fog effects for positioning error, hits, and probability affect the success rate. The third article “Applying Fog Analysis Tool to AFSIM Multi-Domain CLASS scenarios” [3] furthers the verification of FAT to introduce fog across all warfighting domains using a set of Cyber Land Air Sea Space (CLASS) scenarios. The success rate trends with fog impact for each domain scenario support FAT’s effectiveness in disrupting the decision-making process for multi-domain operations. The three ar- ticles demonstrate fog can affect search, tasking, and decision-making processes for various types of wargame scenarios. The capabilities introduced in this thesis support wargame analysts to improve decision-making in AFSIM military scenarios.

Ying Zhao et al, Simulating a Logistics Enterprise Using an Asymmetrical Wargame Simulation with Soar Reinforcement Learning and Coevolutionary AlgorithmsGECCO ’21 Companion, July 10–14, 2021.

We demonstrate an innovative framework (CoEvSoarRL) that lever- ages machine learning algorithms to optimize and simulate a re- silient and agile logistics enterprise to improve the readiness and sustainment, as well as reduce the operational risk. The CoEv- SoarRL is an asymmetrical wargame simulation that leverages re- inforcement learning and coevolutionary algorithms to improve the functions of a total logistics enterprise value chain. We address two of the key challenges: (1) the need to apply holistic predic- tion, optimization, and wargame simulation to improve the total logistics enterprise readiness; (2) the uncertainty and lack of data which require large-scale systematic what-if scenarios and analysis of alternatives to simulate potential new and unknown situations. Our CoEvSoarRL learns a model of a logistic enterprise environ- ment from historical data with Soar reinforcement learning. Then the Soar model is used to evaluate new decisions and operating conditions. We simulate the logistics enterprise vulnerability (risk) and evolve new and more difficult operating conditions (tests); meanwhile we also coevolve better logistics enterprise decision (solutions) to counter the tests. We present proof-of-concept results from a US Marine Corps maintenance and supply chain data set. 

JAMS: Special issue on military wargaming

The latest issue of the Journal of Advanced Military Studies 12, 2 (Fall 2021), published by Marine Corps University Press, is devoted to “wargaming and the military.

Given the rate of change taking place within the Corps and the local activity driving university innovation, the editors felt the need to contribute to the debate with a full issue of the Journal of Advanced Military Studies (JAMS) that focuses on wargaming and the future of the Marine Corps and the U.S. military. The authors of the articles that follow approached the conversation from a broad scholarly spectrum that offers historical and forward-thinking perspectives.

The first article by Dr. Charles Esdaile, “ ‘Napoleon at Waterloo’: The Events of 18 June 1815 Analyzed via Historical Simulation,” offers a historical perspective on the importance of wargaming and professional military education (PME). His article examines how products of the game industry can be used to assess battles and draw out wider lessons relating to the conduct of war or to show how historical board games are not just recreational artifacts but also a tool with which to more fully explore, analyze, and understand campaign design and battle execution.

Sebastian J. Bae and Major Ian T. Brown then provide a transition into a more modern conversation by offering a brief history of educational wargaming specific to the U.S. Marine Corps. The article reviews and assesses the history of educational wargaming from its tentative engagement before World War I through today. It will also offer recommendations on how the Corps can institutionalize the use of educational wargaming as a tool for honing Marines’ minds against thinking human adversaries. Our next two articles continue this discussion of wargaming and PME. Colonel Eric M. Walters considers the challenges and solutions presented by wargaming and helps orient those unfamiliar with wargaming and advises on proven best practices in using them when teaching military judgment in decision making. Lieutant Colonel P. C. Combe II shifts then into the design and implementation of wargaming for the purpose of teaching or evaluating the extent to which students have learned and can apply material as a means of professional development.

Kate Kuehn further highlights the importance of evaluating the use of wargaming with her article, “Assessment Strategies for Educational Wargames.” Kuehn maintains that by examining the perspectives and practices of experi- enced faculty within wargaming, she can then identify strategies that can serve as useful teaching tools for other faculty as well as contribute to broader theory about designing assessment in such spaces. Colonel Brian W. Cole’s article on the wargame Hedgemony focuses on using wargames to then evaluate the learning objectives within senior Joint PME. His article examines how the Marine Corps War College’s experience with Hedgemony offers active learning for its students while emphasizing resource management and evaluates how well the game met the educational objectives set forth by the Joint Chiefs of Staff for senior-level PME.

The final two articles in this issue of JAMS close the loop on the PME continuum by focusing on how wargaming complements military decision making and the future development of wargaming focused on the future of warfare. Colonel Walters’s article “Developing Self-Confidence in Military Decision Making” highlights how extensive practice through wargaming grows self-confidence in both the individual Marine and in the unit engaged in it. Stephen M. Gordon, Colonel Walt Yates, and Andrew Gordon close out the journal articles by exploring the benefits and challenges of applying successful storytelling techniques to designing wargame narratives that balance creative ambitions with achievable time lines. In the authors’ minds, wargames that incorporate such techniques will generate new trends and better inform future conflict planning.

Emery: 1950s Political-Military Wargaming at the RAND Corporation

The Texas National Security Review has just published an article by John Emery on “Moral Choices Without Moral Language: 1950s Political-Military Wargaming at the RAND Corporation.”

The RAND Corporation was the site of early-Cold War knowledge production. Its scientists laid the foundations of nuclear deterrence, game theoretic approaches to international politics, defense acquisition, and theories on the future of war. The popularized understanding of RAND as filled with cold, detached rationalists who casually discussed killing millions with no moral abhorrence misses the immense contestation in the early 1950s between the mathematics and the social sciences divisions, which sought to understand the impact of nuclear weapons on war and international politics. To do so, they created the first political-military simulations, called the “Cold War Games.” The games had divergent outcomes, with the mathematicians quick to launch nuclear weapons and the social scientists acting with nuclear restraint. The key difference in the game models was a high degree of realism in the social science game that engaged the players’ emotions. This immersive experience had lasting effects beyond the game itself as defense intellectuals bore the weight of decision-making and confronted the catastrophic consequences of using nuclear weapons. The role of emotion is central to both ethics and decision-making, and is essential for wargaming today, yet often remains excluded in rational theories of nuclear deterrence.

He concludes:

The high degree of realism present in the SSD’s Cold War Game triggered nuclear restraint by engaging the emotions of the players and therefore their ethical intuitions, in contrast to the MAD game, which privileged high levels of abstraction for the sake of mathematical certainty. What was lost in the process was a more cohesive vision of decision-making under uncertainty, all while ignoring the role of emotion in the realm of international politics. Not only are the outcomes of the game boxed in by initial assumptions in operationalizing variables that can fall out instantaneously in the real world, but a high level of abstraction produces a detached theorizing in which a kind of ethical practical judgment can also be lost. Reason cannot be separated from emotion and imagined futures are as powerful as the study of the past.

These political-military games at RAND have important lessons for thinking through the implications of emotion, ethics, and the role of judgment in wargaming today. Given the current renaissance in wargaming — in the social sciences as well as in efforts to think through the dilemmas of AI and the future of war — it is important to reflect on the issues raised by RAND in the 1950s and the lessons that can be drawn from them. First, reason and emotion are inextricably intertwined. They exist in a symbiotic relationship in terms of how we experience and interpret the world. Second, wargames with a high degree of realism can better represent decision-making in the real world by engaging the emotions of the players. Third, even when ethics is excluded from the conversation, facing the potential consequences of political-military action can lead to restraint. Finally, a conversation of realistic consequences and the uncertainties of the world is essential for an ethical assessment of possible consequences of nuclear threat and use. Wargames can be more than the division between art and science or quantitative and qualitative approaches, but a quest for understanding the why of decision-making, beyond the discursive reasons that players may give. The technostrategic language that Cohn wrote about in the 1980s remains pervasive in nuclear deterrence circles, but the revival of simulations and gaming in the social sciences offers an opportunity to reflect upon the importance of emotion and ethical practical judgment in international relations. Being made to feel the weight of decision-making is a necessary antidote to abstractions that allow policymakers to ignore the real consequences and human suffering that could come from pressing the button.

Christensen and Dobias: Wargaming the use of intermediate force capabilities in the gray zone

In a forthcoming article in the Journal of Defense Modeling and Simulation, Kyle Christensen and Peter Dobias of Defence Research and Development Canada discuss wargaming the use of intermediate (nonlethal) force capabilities in the “gray zone.”

Military operations in the gray zone (defined here as the space between peace and war where states are currently involved in a competition continuum) present a unique challenge for military planners. Often tactical actions can have significant operational, and even strategic implications. This makes traditional modeling approaches, such as wargames, of somewhat limited applicability. This limitation can be further exacerbated if the modeled systems are intended to address specific adversarial actions within the gray zone continuum across tactical and operational levels. A specific example of such a problem is modeling military capabilities at the force continuum between inaction and employment of lethal force. Whereas the tactical effectiveness of such systems may be lower than the effectiveness of lethal systems (e.g., if there is a requirement to stop an incoming threat, the use of lethal force is often more effi- cient than the use of acoustic or optical warning devices), the operational and strategic effectiveness of their use would likely be better.

In the summer of 2020, the NATO’s Science & Technology Organization, System Analysis and Studies- 151 (SAS-151) research group conducted a series of test wargames to evaluate whether intermediate force capabil- ities (IFCs) can make a difference to mission success in the gray zone. As described in the following, IFCs offer a class of response between doing nothing and using lethal force in a situation that would be politically unpalatable. This article reviews NATO SAS-151’s development and tests of an IFC concept development wargame aimed at examining a maritime task force’s ability to counter hybrid threats in the gray zone. It covers the strategic context and background of hybrid threats in the gray zone; the conceptual background and development of non-lethal weapons (NLW) through to IFCs; the design and development of the hybrid wargame methodology; and the implementation and execution of the test IFC wargame(s), with initial observations where applicable.

This wargame series was particularly important for two reasons. First, it explored an operational challenge facing many Western militaries in the current strategic environment where opponents and adversaries are using hybrid threats (i.e., tactics and techniques) to deny traditional Western military freedom of action. However, rather than challenge Western militaries in head-to-head confrontations, these tactics aim to remain below the threshold of open conflict, and create strategic, operational, and/or tactical dilemmas for decision-makers. They blur the line between strategic, operational, and tactical, and exploit situations where tactical decisions/actions have strategic impacts.

Second, it used traditional game mechanics in a unique and innovative way to evaluate and assess IFCs. While the concept of using kriegsspiel and/or matrix wargames by themselves to develop and test concepts, inform decision-making, and validate capability requirements are not new, combining both into a single hybrid wargame is new. The approach described in this article was to execute a modified strategic matrix wargame to assess the outcome of an initial tactical level free kriegsspiel engagement game. Although the key components of a kriegsspiel and matrix game are retained, how they are set up, and how they are used together to approach the problem of assessing IFCs in the gray zone is a unique adaptation of these traditional games.

Hanley: A critique of strategic operational gaming

PAXsims is pleased to share John Hanley’s 1991 PhD thesis, On Wargaming: A Critique of Strategic Operational Gaming (Yale University, 1991).

This paper is a critique of strategic operational gaming. Operational gaming refers to the use of gaming to explore plans and investigate courses of action. Strategic refers to the subject explored. Therefore, this inquiry deals with two topics. One is the limits and validity of knowledge derived from operational gaming. The other is the use of free­ form gaming involving humans in formulating national security strategy.

This work consists of five parts in ten chapters. Part one addresses free-form gaming. Rather than accepting the notion that gaming contributes to better decisions, it addresses the alternatives to gaming and the issue: Why Game? This chapter uses a taxonomy of indeterminacy to suggest classes of problems most amenable to gaming. Part two suggests why we should employ operational gaming seriously as a technique in the formulation and implementation of national security strategy. It addresses the evolving nature of national security strategy, the history of gaming, and the influence of gaming on policy and strategy. Part three explicitly lays out the elements and structure of operational gaming. Part four critiques two current efforts employing operational gaming techniques to assist in national security policy analysis and strategy formulation. Similar concerns over defects in strategic analysis at the end of the 1970s led to the Global War Games at the Naval War College and the RAND Strategy Assessment System. The Global games employ free-form gaming whereas RAND has developed a computer-based system. Finally, part five addresses future directions in the use of operational gaming for policy analysis and strategy formulation. It suggests steps needed to institute a discipline of gaming and suggests areas of research.

Sabin on strategic wargaming

Earlier this month, Prof. Philip Sabin delivered a presentation on “what strategic wargaming can teach us” to the German Institute for Defence and Strategic Studies. The text of that presentation is now available online.

Review: Gaming Disease Response

ED McGrady and John Curry, Roll to Save: Gaming Disease Response (History of Wargaming Project, 2021). 143pp. USD$20 paperback, USD$7.92 Kindle.

The current COVID-19 pandemic has underscored the value of serious gaming for supporting health sector preparedness and government policy response. Indeed, in my own case, during the past year I have found myself designing games on pandemic-related food security issues, working with the Public Health Agency of Canada and Department of National Defence in red teaming Canada’s national vaccine roll-out plans (including a major national tabletop exercise), and I’m currently working with the READY Initiative on digital games-based training for epidemic disease preparedness and response in the humanitarian sector.

All of that is to say that I wish Roll to Save: Gaming Disease Response had been published a year ago, because it is a very useful resource indeed for anyone working in this area. Some of the chapters address general design issues, including the value of serious games; gaming at the strategic (policy), operational, and “tactical” levels of disease response; and important considerations in professional game design. Other chapters discuss particular game designs, addressing topics as wide-ranging as vaccination/prophylaxis; bioterrorism (anthrax, melioidosis); particular epidemic outbreak scenarios (ebola); mental health support; and pandemic recovery (COVID-X). It also contains brief chapters discussing some of the basics of infectious diseases, epidemiology, public health planning, outbreak investigation, and the importance of information, politics, and the media. My only disappointment was the bibliography, which lists some of the sources cited in the book but which doesn’t provide a wider reference to the substantial literature on medical and emergency preparedness gaming.

Above and beyond the very considerable value of this publication for those designing disease response games, it also stands as an excellent example of how serious gaming should be undertaken. McGrady not only has extensive experience in designing and implementing serious games on a wide range of national security and policy issues, but also has keen insight into what works in what context. He thus underscores the importance of designing a game around not only the topic, but equally the game objectives, available resources, participants, and client/sponsors.

Christensen, Kyle (2021). “Wargaming the use of intermediate force capabilities in the gray zone,” Journal of Defense Modeling and Simulation: Applications, Methodology, Technology (online first).

This work reviews the development and tests of an intermediate force capability (IFC) concept development hybrid wargame aimed at examining a maritime task force’s ability to counter hybrid threats in the gray zone. IFCs offer a class of response between doing nothing and using lethal force in a situation that would be politically unpalatable. Thus, the aim of the wargame is to evaluate whether IFCs can make a difference to mission success against hybrid threats in the gray zone. This wargame series was particularly important because it used traditional game mechanics in a unique and innovative way to evaluate and assess IFCs. The results of the wargame demonstrated that IFCs have a high probability of filling the gap between doing nothing and using lethal force. The presence of IFCs provided engagement time and space for the maritime task force commander. It also identified that development of robust IFC capabilities, not only against personnel, but against systems (trucks, cars, UAVs, etc.), can also effectively counter undesirable adversarial behavior

Hill, Richard T.; Hirtz, Derek (2020), Rebels and States: A Game Of Revolution And Dominance, MSc thesis, US Naval Postgraduate School. 

The U.S. military is currently in an era of change highlighted by a shift in focus from small-scale and limited wars involving counterterrorism (CT) and counterinsurgency (COIN) to preparations for large-scale combat operations with a near-peer threat. This shift has placed emphasis on conventional focus in training, education, and planning to stand ready for a potential conflict as the United States continues to maintain its unilateral grip as the world’s lone superpower, and Russia and China try to expand their spheres of influence in the great power competition (GPC). But as with the Cold War, it is unlikely this showdown will occur. Conversely, it is far more probable conflict will be highlighted by competition through state-sponsored insurgencies, proxy wars, and a struggle over influence. Special operations forces (SOF) therefore must balance their understanding and preparedness of conventional warfare while standing ready to execute unconventionally. This wargame is designed to train entry-level SOF candidates in the interaction between the insurgent and counterinsurgent, utilizing COIN and unconventional warfare (UW) doctrine as a basis while also employing the concepts of insurgent, resistance, and COIN theorists. The goal of the wargame is to aid SOF candidates as they prepare to serve in their operational units, providing a venue to test strategies and understandings of COIN and UW principles, and ensure an enhanced education in doctrine and theory.

Jaramillo-Alcázar, Angel; Venegas, Eduardo ; Criollo-C, Santiago; and Luján-Mora, Sergio. (2021). “An Approach to Accessible Serious Games for People with Dyslexia,” Sustainability 13.

Dyslexia is a cognitive disorder that affects the evolutionary ability to read, write, and speak in people, affecting the correct learning of a large percentage of the population worldwide. In fact, incorrect learning is caused because the educational system does not take into consideration the accessibility parameters that people with dyslexia need to maintain a sustainable educational level equal to others. Moreover, the use of mobile devices, such as smartphones and tablets, has been deployed in education programs, offering many benefits; however, the lack of accessibility of those devices creates new barriers to students with dyslexia that hinder their education. With the aim of reducing these barriers, this paper presents an approach to the development of accessible serious games games for children with dyslexia. As a case study, a serious game based on a previously proposed serious game development method and a new set of accessibility guidelines for people with dyslexia is presented. The main purpose of the serious video game is to improve the treatment of dyslexia, through the collection of data obtained from two puzzles designed to train certain cognitive areas that affect this disability. This article has a double contribution: on the one hand, the guidelines and the method that can help video game developers and therapists to develop accessible serious games for people with dyslexia and, on the other hand, the two specific serious games that can be used by therapists, family members and people with dyslexia themselves. 

Lim, Jong-Won; Choi, Bong-Wan; Yim, Dong-Soon (2021).  “A Study on the Methodology for Combat Experimental Testing of Future Infantry Units using Simulation,” Journal of the Korea Academia-Industrial Cooperation Society 22(3).

Owing to the development of science technology, particularly the smart concept and defense policy factors of the 4th industry, military weapon systems are advanced, and the scientific and operational force is reduced dramatically. The aspect of the future war is characterized by the operation of troops with reduced forces from advanced and scientific weapon systems in an operational area that has expanded more than four times compared to the present. Reflecting on these situational factors, it is necessary to improve combat methods based on the changes in the battlefield environment and advanced weapon systems. In this study, to find a more efficient future combat method in a changing war pattern, this study applied the battle experiment methodology using Vision21 war game model, which is an analytical model used by the army. Finally, this study aimed to verify the future combat method and unit structure. Therefore, the scenario composition and experiment method that reflect the change in the ground operational environment and weapon system was first composed. Subsequently, an analysis method based on the combat effectiveness was applied to verify the effective combat performance method and unit structure of future infantry units.  [In Korean]

Lu, Tongliang; Chen, Kai; Zhang, Yan; Deng, Qiling (2021). “Research on Dynamic Evolution Model and Method of Communication Network Based on Real War Game,” Entropy 23(4).

Based on the data in real combat games, the combat System-of-Systems is usually composed of a large number of armed equipment platforms (or systems) and a reasonable communication network to connect mutually independent weapons and equipment platforms to achieve tasks such as information collection, sharing, and collaborative processing. However, the generation algorithm of the combat system in the existing research is too simple and not suitable for reality. To overcome this problem, this paper proposes a communication network generation algorithm by adopting the joint distribution strategy of power law distribution and Poisson distribution to model the communication network. The simulation method is used to study the operation under continuous attack on communication nodes. The comprehensive experimental results of the dynamic evolution of the combat network in the battle scene verify the rationality and effectiveness of the communication network construction

Tanner Mirrlees, Tanner, and Ibaid, Taha (2021). “The Virtual Killing of Muslims: Digital War Games, Islamophobia, and the Global War on Terror,” Islamophobia Studies Journal 6 (1).

This article argues that digital war games communicate misleading stereotypes about Muslims that prop up patriarchal militarism and Islamophobia in the context of the US-led Global War on Terror. The article’s first section establishes the relevance of the study of digital war games to feminist games studies, feminist international relations, and post-colonial feminism. The second section contextualizes the contemporary production and consumption of digital war games with regard to the “military-digital-games complex” and real and simulated military violence against Muslims, focusing especially on the US military deployment of digital war games to train soldiers to kill in real wars across Muslim majority countries. The third section probes “mythical Muslim” stereotypes in ten popular digital war games released between 2001 and 2012: Conflict: Desert Storm (2002), Conflict: Desert Storm 2 (2003), SOCOM U.S. Navy SEALs (2002), Full Spectrum Warrior (2004), Close Combat: First to Fight (2005), Battlefield 3 (2011), Army of Two (2008), Call of Duty 4: Modern Warfare (2007), Medal of Honor (2010), and Medal of Honor: Warfighter (2012). These games immerse players in patriarchal fantasies of “militarized masculinity” and place a “mythical Muslim” before their weaponized gaze to be virtually killed in the name of US and global security. The conclusion discusses the stakes of the stereotyping and othering of Muslims by digital war games, and highlights some challenges to Islamophobia in the digital games industry.

Satopää, Ville and Salikhov, Marat and Tetlock, Philip and Mellers, Barb, (2021). Decomposing the Effects of Crowd-Wisdom Aggregators: The Bias-Information-Noise (BIN) Model, SSRN.

Aggregating predictions from multiple judges often yields more accurate predictions than relying on a single judge: the “wisdom-of-the-crowd” effect. This aggregation can be conducted by different methods, from simple averaging to complex techniques, like Bayesian estimators and prediction markets. This article applies a broad set of aggregation methods to subjective probability estimates from a series of geopolitical forecasting tournaments. It then uses the Bias-Information-Noise (BIN) model to disentangle three mechanisms by which each aggregation method improves accuracy: the tamping down of bias and noise and the extraction of valid information across forecasters. Averaging works almost entirely via noise reduction whereas more complex techniques, like prediction markets and Bayesian aggregators, work via all three BIN pathways: better signal extraction and noise and bias reduction.

Krewani (eds.), Media and Mapping Practices in the Middle East and North Africa: Producing Space. Amsterdam: Amsterdam University Press.

Shortly after the end of a tank combat during the Gulf War, a team of US Army historians, scientists, and engineers flew to Iraq to gather detailed data of the battle. The collected information was used to create an exact virtual simulation of the combat for training. The mapping capability – offered by the resulting simulation game 73 Easting – to visualize the battlefield from any position and point in time revolutionized military exercises. With ongoing conflicts in the Middle East, these digital training cartographies are now linked to real bodies and vehicles through digital and mobile technologies during live training in artificially constructed villages. This chapter analyses this evolution and critically investigates the growing ‘gamification’ ensuing in these representations of Middle Eastern battlefields.

Sang-Hyun Ahn, Jitae Kim, Il-Moon Chung, Jeong Eun Lee, “Domestic and Foreign Case Studies of Virtual Drought Exercise,”  Journal of Engineering Geology (December 2020) [in Korean].

Drought has repeatedly occurred due to the climate change effect. The government is working on ways to reduce drought damage and is conducting drought exercise. This study analyzed drought literature and exercise cases in the United States, Australia and Korea. Based on the analysis results, the study suggested considerations in selecting exercise types which are workshop, tabletop exercise and functional exercise, and process of the drought exercise. The results of the study can be used as an effective tool to prepare the virtual drought exercise. 

Rex Brynen, “Virtual paradox: how digital war has reinvigorated analogue wargaming,” Digital War 1, 1 (2020).

War has become increasingly digital, manifest in the development and deployment of new capabilities in cyber, uncrewed and remote systems, automation, robotics, sensors, communications, data collection and processing, and artificial intelligence. The wargames used to explore such technologies, however, have seen a renaissance of manual and analogue techniques. This article explores this apparent paradox, suggesting that analogue methods have often proven to be more flexible, creative, and responsive than their digital counterparts in addressing emerging modes of warfare.

Warfare has become increasingly digital. Militaries around the world are developing, deploying, and employing new capabilities in cyber, uncrewed and remote systems, automation, robotics, sensors, communications, data collection and processing, and even artificial intelligence. The wargames used by governments to explore such technologies, however, have seen a renaissance of manual and analogue techniques. What explains this apparent paradox?

This article will explore three reasons why analogue gaming techniques have proven useful for exploring digital war: timeliness, transparency, and creativity. It will then examine how the field of professional wargaming might develop in the years ahead. To contextualize all of that, however, it is useful to discuss wargaming itself. How and why militaries use games to understand the deadly business of warfare?

Andreas Haggman, “Imagining and Anticipating Cyber Futures with Games,” in A. Ertan, K. Floyd, P. Pernik, T. Stevens, eds., Cyber Threats and NATO 2030: Horizon Scanning and Analysis (NATO Cooperative Cyber Defence Centre of Excellence, 2020).

This short chapter considers the relationship between games and futures, with specific focus on cyber security. Games and gamification have received renewed attention in both academia and industry over the past ten years. Within this broad field, the genre of wargaming occupies a significant but often underappreciated space.

Unlike what some observers might argue, wargaming is not just an activity for history anoraks with an overly keen interest in the past. Wargaming can indeed be used to better understand historical events, but it can also be used to explore the dynamics of the present or employed as a highly imperfect crystal ball to gaze into the future. When done right, wargaming can be a powerful tool to engage audiences with little subject matter expertise or game playing experience.

Three core arguments are made in this chapter. First, wargames can provide structure for players to imagine futures. Second, wargames can prepare players for the future by enabling them to anticipate emotions. Lastly, cyber wargames should avoid the trap of becoming enamoured with the technolo- gy of cyber security.

The chapter is grounded in diverse literature, drawing on material from cultural studies, strategic studies, modelling and simulation and history. Readers will find theoretical insights into the uses of games alongside prac- tical advice for those seeking to use wargames in a cyber security context.

Shang Jiang, Wenxia Wei, Yanlin Wu, Rui Tang, Qingquan Feng, Daogang Ji, “War Chess as Hierarchical Learning Environment,” 13th International Symposium on Computational Intelligence and Design (2020).

This paper introduces GWCLE (General War Chess Learning Environment), a general machine learning environment based on hexagonal wargaming. Hexagonal war chess, when utilized as machine learning challenge, is naturally a multi-agent problem with the intelligent interaction of human or machine. The GWCLE supports hybrid engine, allowing credible simulation for kinds of war chess, which provides hierarchical training framework for massive agents control problem. The agent can be trained with designated level of war chess data and transferred bottom-up or top-down. For training on the whole deduction, we build the database to store refined replay data. Our framework is able to support agents to be trained in tactical and strategic level simultaneously. GWCLE offers a hierarchical perspective of the war chess simulation, allowing researchers controlling the granularity of action and time step.

Thorsten Kodalle, Terra Schwartz, David Ormrod, C. Sample, K. Scott, “A General Theory of Influence in a DIME/PMESII, ASCOP/IRC Model,” Journal of Information Warfare 19, 2 (2020).

The leading question of this paper is “How can one conceptualise influence warfare in order to simulate it?” The authors discuss the foundational aspects of theory and model of influence warfare by building a conceptual framework. The framework forms a prism with three axes along the DIME/PMESII/ASCOP dimensions. The DIME concept groups the many instru- ments of power a nation-state can muster into four elements: Diplomacy, Information, Military, and Economics. PMESII describes the operational environment in six domains: Political, Mili- tary, Economic, Social, Information, and Infrastructure. ASCOPE is used in COunterINsurgen- cy (COIN) environments to analyse the cultural and human environment (the ‘human terrain’) and encompasses Areas, Structures, Capabilities, Organization, People, and Events. Addition- ally, the model reflects about aspects of Information Collection Requirements and Information Capabilities Requirements (ICR2)—hence DIME/PMESII/ASCOP/ICR2. The paper focuses on building a framework for the problem space of influence/information/hybrid warfare and intro- duces the idea of the perception field, understood as a molecule (gestalt or shape) of a story or narrative that influences an observer. This molecule can be drawn as a selection of vectors that can be built inside the DIME/PMESII/ASCOP prism. Each vector can be influenced by a shielding or shaping action. These ideas are explored in the context of an influence wargame.

Robert Körner and Astrid Schütz, “It is not all for the same reason! Predicting motives in miniature wargaming on the basis of personality traits,”  Personality and Individual Differences 173 (April 2021).

Despite the increasing popularity of miniature wargames (MWGs), research on this pastime is still scarce. We aimed to understand how personality is related to motivations for playing MWGs. A world sample of 8590 MWG players was tested with the Ten-Item Personality Inventory to assess the Big Five and the Trojan Player Typology to measure gaming motivations. The latter scale was used for the first time in non-video-game players and showed good psychometric properties. Results showed several significant associations between personality and motivations for engaging in these games. People who played MWGs to socialize were high in openness and extraversion. Players high in agreeableness did not want to compete and did not emphasize winning as an important factor. People who played to escape from everyday problems reported high levels of neuroticism. Story-driven gamers described themselves as open and agreeable. Clearly, personality is relevant for predicting the attractiveness of MWGs, and the game has different aspects of attractiveness for different groups. The results help to better explain the phenomenon of MWGs and highlight the role of personality in this pastime. Avenues for future research such as the use of behavioral measures in playing MWGs are discussed.

Miriam Matejova and Chad M. Briggs, “Embracing the Darkness: Methods for Tackling Uncertainty and Complexity in Environmental Disaster Risks,” Global Environmental Politics 21, 1 (February 2021).

Environmental systems are complex and often difficult to predict. The interrelationships within such systems can create abrupt changes with lasting impacts, yet they are often overlooked until disasters occur. Mounting environmental and social crises demand the need to better understand both the role and consequences of emerging risks in global environmental politics (GEP). In this research note, we discuss scenarios and simulations as innovative tools that may help GEP scholars identify, assess, and communicate solutions to complex problems and systemic risks. We argue that scenarios and simulations are effective at providing context for interpreting “weak signals.” Applying simulations to research of complex risks also offers opportunities to address otherwise overwhelming uncertainty.

Daniel F. Oriesek, Jan Oliver Schwarz, Winning the Uncertainty Game: Turning Strategic Intent into Results with Wargaming (Routledge, 2020).

This book is about the challenges that emerge for organizations from an ever faster changing world. While useful at their time, several management tools, including classic strategic planning processes, will no longer suffice to address these challenges in a timely and comprehensive fashion. While individual management tools are still valid to solve specific problems, they need to be employed based on a clear understanding of what the greater challenge is and how they need to be combined and prioritized with other approaches. In order to do so, companies can apply the clarity of thinking from the military with regard to which leadership level is responsible for what and how these levels need to interact in order to produce a single aligned response to an outside opportunity or threat. Finally, the tool of business wargaming, while known for some time, proves to be an ideal approach to quickly and effectively bring all leadership levels together, align them around a common objective and lay the groundwork for effective implementation of targeted responses that will keep the organization competitive and in the game for the long run.

The book offers a comprehensive introduction to business wargaming, including a historical account, a classification of different types of games and a number of specific real-world examples. 

This book is targeted at practicing managers dealing with the aforementioned challenges, as well as for students of business and strategy at every level.

This collection advances current scholarly thinking by integrating insights from across a range of disciplines on how to effectively design, execute, and evaluate simulations, leading to a deeper understanding of how SBE can be used to cultivate skills and capabilities that students need to achieve success after graduation.

James Smith, “New Research into the History, Theory and Practice of Naval Wargaming,” The Mariner’s Mirror 107 (2021).

It is largely overlooked today that naval war- gaming was a major contributing factor not only to the development of British naval thought but also to strategic theory. In academia and in government, naval wargaming has often been disregarded and its importance to the development of the art and theory of war neglected. It has been viewed purely through the eyes of a land narrative. The disparity between land and sea wargaming rose to prominence in 2016 when the author regenerated naval wargaming in the War Studies Department at King’s College London, which was met with an array of suspicious questions, often from historians. Projects on the history of wargaming and its many branches have been undertaken previously by the wargaming community, but they failed to set their research in a wider context. They had become reliant on the same, often secondary, sources as a cornerstone of their understanding of the history of naval war- gaming. To their consternation, these were some of the factors behind why wargamers continued to face the same questions repeatedly on the role and function of wargames. They often failed to demonstrate that naval wargaming was both a practical tool and an enabling agent for the disciplines and topics that it has supported. Examples could have been easily shown from the wider narrative of wargaming, and their interpretation was not just dependent on the classified wargaming found in late twentieth- and early twenty-first-century defence practice. With this in mind, the Society for Nautical Research supported a project to fill a gap in knowledge and address these issues in a scholarly manner. Addressing these multide of imbalances, the research has identifed that naval wargaming became an essential tool to support not only historical discussion of naval topics and questions, but was also critical to the development of strategic theory. This report summarizes the initial findings.

Hanchao Wang, Hongyao Tang, Jianye Hao, Xiaotian Hao, Yue Fu, Yi Ma, “Large Scale Deep Reinforcement Learning in War-games,” 2020 IEEE International Conference on Bioinformatics and Biomedicine (2020).

War-game is a type of multi-agent real-time strategy game, with challenges of the large-scale decision-making space and the flexible and changeable battlefield situation. In addition to the military field, it has played a role in fields including epidemic prevention and pest control. In recent years, more and more learning algorithms have tried to solve this kind of game. However, the existing methods have not yet given a satisfactory solution for the war-game, especially when preparation time is limited. In this background, we try to solve a traditional war-game based on hexagon grids. We propose a hierarchical multi-agent reinforcement learning framework to rapidly training an AI model for the war-game. The higher-level network in our hierarchical framework is used for task decision, it solves the credit assignment problem between agents through cooperative training. The lower-level network is mainly used for route planning, and it can be reused through parameter sharing for all the agents and all the maps. To deal with various opponents, we improve the robustness of the model through a grouped self-play approach. In experiments, we get encouraging results which show that the hierarchical structure allows agents to learn their strategies effectively. Our final AI model demonstrates that our methods can effectively deal with the challenges in the war-game.

Nan Wang and Miao Shen, “Foreseeing the Subversive Influence of Intelligent Simulation Technology for Battle Example Teaching,” International conference on Big Data Analytics for Cyber-Physical-Systems (2020).

It is an important research project that exploring battle example teaching is how to serve the fight and drill preferably. The simulation territory has introduced artificial intelligence, virtual reality and cloud computing at present, the simulation based on these techniques will bring far-reaching influence for battle example teaching. The intelligent simulation technology will remodel analysis factors of battle example, reconstitute research idea of battle example, overturn the research of battle example. The battle example teaching methods based on intelligence confrontation, scene recurrence and fight chess manoeuvre will show itself, and it will help researchers capture victory inspiration from battle example, feel command art in virtual confrontation and excavate defeating mechanism from retrospect research.

Andrew P. Betson, Tristan Boomer,  Justin DiCarlo, Marshall Green and Adam Messer, “COVID-19 and Virtual Wargaming in the Reserve Officer Training Corps: Deadly Virus Resurrects Aged Tactical-Training Method,” Armor (Fall 2020).

The Coronavirus Disease 2019 (COVID-19) pandemic stopped the world in its tracks early in 2020. As unfamiliar terminology such as “social distancing” and “reducing the curve” proliferated everyday life, military leaders faced familiar (and unceasing) training requirements despite the unexpected challenges that arise from a pandemic.

At St. Louis’s Army Reserve Officer Training Corps (ROTC) Gateway Battalion, the story was the same. Universities across the city closed in March, and students were sent home, prompting the need for a new solution to fulfill training requirements. Our ROTC program’s third-year cadets were expected to be trained (or, at least practiced “P+”) in leader and collective tasks for platoon-level tactical operations and in warrior tasks and drills. With unprecedented levels of technology and communication at our fingertips, the cadre and the fourth-year cadet leadership of Gateway Battalion looked to the Prussians of the early 1800s and U.S. Army Reserve units of the 1980s for help. The result succeeded beyond expectations when it came to training our cadets.

Matthias Caretta Crichlow, A Study on Blue Team’s OPSEC Failures (Faculty of Electrical Engineering, Mathematics & Computer Science, University of Twente, October 2020).

Organizations are every day expanding their networks, increasing the number of servers and workstations in it. Such a growth expands the surface that can be tar- geted by malicious actors to cause harm. Therefore it is becoming more and more common for the organizations to create specialized teams of defenders (i.e. the Blue Team) who can monitor and protect their system. However, the fact that someone is actively hunting for malicious actors changed the balance in cybersecurity. Inter- acting with the attackers causes change in their strategies. We focused our efforts in studying the interplay between attackers and defenders, aiming at creating fur- ther studies in this new field. As the first step we tried to understand what part of the Blue Team investigations can be detected by an intruder, and we highlighted the fact that indicators of Blue Team’s OPSEC failures are the way attackers can likely achieve these results. We focused our study on the first line of defence within the Blue Team, the SOC (Security Operation Center). Using CTA (Cognitive Task Analysis) techniques we identified common OPSEC failures among SOC analysts. Subsequently, in order to evaluate the impact that such actions have on the strate- gies of attackers we organized a wargame in collaboration with Northwave’s Red Team demonstrating that being aware of the Blue Team’s presence determined the adoption of more cautious behaviour in the attacker. In order to achieve our goal we developed a new CTA technique that can be used to further study Blue Team’s cognitive processes. Additionally, we addressed a major problem within the cyberse- curity research community by developing a reusable virtual environment with built-in monitoring capabilities that can be used to create experiments that can be easily verified by other researchers. 

Johan Elg, “Instructor Buy-In: Pitfalls and Opportunities in Wargaming,” KKrVA Handlingar och Tidskrift 2 (April/June 2019).

Wargames are a fundamental part of military training. Still, wargames are controversial, with recurring cycles of appreciation and disapproval. Wargames can be defined as one conditional interaction with human players affecting simulated military actions. The purpose with this text is to examine and explain how military instructors alleviate their worries – more about handling a wargame. The text analyzes relevant publications on educational games to highlight the issue of instructors and wargames. This method is complemented by new and exploratory research, which includes grounded theory, regarding the substantial empirical the area of ​​war games for military training. Military instructors use three strategies to achieve instructor acceptance ( instructor buy-in). A majority of the instructors strive to avoid explicit gameplay (gamification ). This avoidance constitutes a explanation for the change or cessation of certain wargames in military education. For this reason, it is vital that military instructors have an understanding of instructor acceptance to strengthen the practice of wargames.

Experimental Design (ED) technique is a proven analytical method used in the chemicals industry. We have taken this approach and applied it to Phil Sabin’s ‘Take That Hill’, a simple wargame presented at Connections 2014. By evolving the tactical turn game choices into playable full-game strategies, a descriptive set of game outcomes can be delivered and optimised to produce winning strategies. This provides a systematic approach to testing a game, with full post-game deconstructive analysis which is capable of being used to identify flaws, and find optimal strategies in playing the game. The most successful strategies found by ED outperformed individual strategies developed by experienced players. ED allowed pairing of obvious good play with seemingly counterintuitive play that were found to work well in unexpected combinations.

Simulations and Student Learning is the first piece of scholarship that brings together experts from the social, natural, and health sciences in order to open up new opportunities for learning about different strategies, methods, and practices of immersive learning. This collection advances current scholarly thinking by integrating insights from across a range of disciplines on how to effectively design, execute, and evaluate simulations, leading to a deeper understanding of how SBE can be used to cultivate skills and capabilities that students need to achieve success after graduation.

Noa Shusterman, Udi Dekel, The Coronavirus in Gaza: Insights from a War Game (Institute for National Security Studies, 13 April 2020).

A war game simulating a large scale outbreak of the coronavirus in the Gaza Strip underscored that Israel has no way to prevent a spread of the pandemic in Gaza, but it can take steps to alleviate the situation. Among the principal proposals: Israel should already transfer vital medical aid to the Gaza Strip; work with the World Health Organization and other relief agencies to mobilize medical resources for the area; avoid obstructing any initiative to establish an emergency government by the Palestinian Authority and Hamas; and prepare to set up emergency assistance infrastructure on Israeli territory adjacent to the Strip.

Jeremy Smith, Stephen Barker, “Methods to measure and track population perception and support within a manual wargame,” Journal of Defense Modelling and Simulation: Applications, Methods, Technology (online first 15 October 2020)

The outcomes of military campaigns depend to a large extent on the support of local and other wider population groups, so it is important to understand their perceptions. Here we briefly describe the approach used to represent support for organizations and factions in a professional wargame designed to represent military campaigns. This specific approach was developed originally using a simple marker track system that used a basic quantified set of relationships between military campaign effects and changes to the track levels. This marker track system was developed for military campaign wargames in the UK as a means to portray support or dissent in population groups relevant to the operations, but there was originally no mechanism to drive changes other than by expert judgment. Our improved approach continues the use of marker tracks but attempts to develop a more defensible method based on Maslow’s hierarchy of needs for linking events to changes and levels on the tracks. We conducted experiments to quantify the relative importance of each element in Maslow’s hierarchy. We then continued by conducting a further experiment to identify the impact of a set of effects seen in a wargame against the Maslow elements. This has led to a set of quantified scores that may be used to drive the modifications to the marker tracks when wargame events occur. These scores are based on our initial experiments and may be updated for a specific application, perhaps for a specific setting or location in the world. The revised or enhanced approach aims to produce a transparent solution that can be understood by a military or security analyst, thus facilitating refinement, updating, and change.

Review: The Craft of Wargaming

Jeff Appleget, Robert Burks, and Fred Cameron, The Craft of Wargaming: A Detailed Planning Guide for Defense Planners and Analysts (Annapolis: Naval Institute Press, 2020). $39.95 hc, $31.92 Kindle.

The Craft of Wargaming is a very useful book that guides the reader through the initiation, design, development, conduct, and analysis of wargames. The focus here is primarily on process—unlike Sabin’s Simulating War (2012), there is not much included on how to model time, space, or combat. Instead, the contribution is more akin to that made by Perla’s Art of Wargaming (1990), the Naval War College’s War Gamer’s Handbook , or Longley-Brown’s Successful Professional Wargaming (2019). The focus is on analytical wargames, although one chapter is devoted to educational and experiential games.

One notable feature of The Craft of Wargaming is the integration of a series of ten practical exercises, built around an included wargaming scenario: a stabilization operation in the fictional country of Zefra. This makes the volume especially useful for teaching purposes (provided, of course, students don’t read ahead to the suggested answers). A suggested “wargaming gateway exam” is included too, based on the material in the book. Finally, eight additional wargaming case studies are appended, ranging from fleet design to hybrid warfare to tactical naval operations. The book’s clarity and structure also make it very suitable for use as a self-learning guide.

All-in-all, the Craft of Wargaming is a valuable contribution to the field.

Recent simulation and gaming publications, August/September 2020

PAXsims is pleased to present a selection of recently-published items on simulation and serious gaming. Some of these may not address conflict, peacebuilding, or development issues at all, but have been included because of the broader perspective they offer on games-based education or analysis.

A. David Abitbol, “Wargaming influence and information operations,” in United States Advisory Commissionon Public Diplomacy, Teaching Public Diplomacy and the Information Instruments of Power in a Complex Information Environment: Maintaining a Competitive Edge (August 2020).

Developing wargames to effectively model the information environment (IE), and information/influence operations (IO) therein, is challenging for two primary factors. First, conceptualizing the IE is typically difficult due to its complexity. Second, as a rule wargames must necessarily sacrifice some detail for the sake of economy and clarity so as not to overburden participants. This is problematic given that most military professionals have very little ingoing experience with and corresponding understanding of operations in the information environment. The IE wargame participant learning curve is steep.

Overcoming these hurdles and designing practical simulations is critical to improving familiarity of IO for policymakers and maneuver commanders alike. This paper summarizes the U.S. Army War College’s approach to wargaming and modeling information warfare (IW), which has been under my direction since 2018.1 I describe
our efforts to effectively model the IE, briefly summarize the relevant scientific literatures underpinning our methods, and then provide the major findings of our wargames within the Joint, Army, and Marine Corps communities.

E. M. Bartels, “Incorporating Gaming into Research Programs in International Relations: Repetition, Game Series, and Multi-Method Analysis,” American Political Science association annual conference, Sepetmber 2020.

Existing literature on the use of games to support research on international relations is largely disconnected from the academic literature on research design generally, and multi-method research design in particular. The majority of gaming literature currently comes out of the interdisciplinary practitioner community, who have generally been focused on pragmatic considerations. Popular works on game design often come out of the commercial gaming industry, where research considerations are not a core driver of design choices. Finally, works from international relations tend to focus on games as a teaching tool or on games as they have contributed to specific avenues of research. It is only recently that the use of games as a tool for research is being addressed as a subject of study it its own right within contemporary political science. As I have previously argued, this turn towards integrating games into the frameworks and concepts applied to other tools for social science research is critical to ensuring that the insights drawn from games are sound, as well as for making gaming as a tool more accessible to new researchers. This paper expands on previous work conceptualizing games within social science research design to discuss how games can be integrated into broader studies by exploring three approaches: repeated games, serial games, and games in multi-methods studies.

James L. Cavallaro and Meghna Sridhar, “Reducing Bias in Human Rights Fact-Finding: The Potential of the Clinical Simulation Model to Overcome Ethical, Practical, and Cultural Tensions in “Foreign” Contexts,” Human Rights Quarterly 42, 2 (May 2020).

This article considers the ethical tensions inherent in international human rights field documentation and proposes intensive, simulation model, pre-fieldwork training as a means of reducing the risk of insensitive encounters. The article evaluates the social, educational, class, racial, and other power imbalances between parties in the ordinary fact-finding process. After mapping pitfalls and challenges, it assesses the simulation training method and its potential to respond to the volatile dynamics of fact-finding. We conclude that the rigorous, three-day or week-long exercise, carried out in a controlled, supervised setting, holds potential to train future advocates to navigate power dynamics, challenges in intercultural engagement, and other communications barriers.

There are inherent difficulties in designing an effective Human–Machine Interface (HMI) for a first-of-its-kind system. Many leading cognitive research methods rely upon experts with prior experiences using the system and/or some type of existing mockups or working prototype of the HMI, and neither of these resources are available for such a new system. Further, these methods are time consuming and incompatible with more rapid and iterative systems development models (e.g., Agile/Scrum). To address these challenges, we developed a Wargame-Augmented Knowledge Elicitation (WAKE) method to identify information requirements and underlying assumptions in operator decision making concurrently with operational concepts. The developed WAKE method incorporates naturalistic observations of operator decision making in a wargaming scenario with freeze-probe queries and structured analytic techniques to identify and prioritize information requirements for a novel HMI. An overview of the method, required apparatus, and associated analytical techniques is provided. Outcomes, lessons learned, and topics for future research resulting from two different applications of the WAKE method are also discussed.

James Goodman, Sebastian Risi, Simon Lucas, AI and Wargaming (study for Dstl, nd, posted2020).

Recent progress in Game AI has demonstrated that given enough data from human gameplay, or experience gained via simulations, machines can rival or surpass even the most skilled human players in some of the most complex and tightly contested games. The question arises of how ready this AI is to be applied to wargames. This report provides a thorough answer to that question, summarised as follows.

Wargames come in a number of forms — to answer the question we first clarify which types we consider.

In order to relate types of wargames to the performance of AI agents on a number of well known games, such as Go and StarCraft, we provide the most comprehensive categorisation to date of the features of games that affect the difficulty for an AI (or human) player.

In the last few years some amazing results have been demonstrated using Deep RL (and Monte Carlo Tree Search) on games such as Go, StarCraft and Dota 2. We review the main architectures and training algorithms used, the level of effort involved (both engineering and computational) and highlight those which are most likely to transfer to wargames.

All the most impressive results require the AI to learn from a large number of game simula- tions. Access to a fast and copyable game engine/simulator also enables statistical forward planning algorithms such as Monte Carlo Tree Search and Rolling Horizon Evolution to be applied. These should be considered as they provide intelligent behaviour “out of the box” i.e. with no training needed, and can be combined with learning methods such as Deep RL to provide even more intelligent play.

Explainable decision making can be achieved to some extent via the visualisation of simula- tions, and by analysing neural network activation patterns to help explain the operation of Deep RL systems. Explainability is best seen as desirable rather than essential.

There is a strong need for a software framework tailored towards wargame AI. There are many examples of successful game AI frameworks, and how they can provide a significant boost to a research area. Whilst no existing one provides adequate support for wargames, we make clear recommendations on what is needed.

Chris Hillier, Analytical wargaming: Enabling operational readiness (Canadian Forces College, May 2019).

This paper will argue that the CAF should revitalize its wargaming capability, specifically focusing on a ‘force on force’ training philosophy that increases the potential for ‘training to failure’. This paper will focus on three areas that support this position. First, it will explore the philosophy that conflict is non-linear, and that dynamic interaction is essential in creating thinking leaders, capable of critical reflection and growth. Second, this paper will explore the US revitalization of analytical wargames, including the United States Transportation Command (USTRANSCOM) lessons learned as a possible case study. Finally, this paper will present potential CAF ‘force on force’ wargaming opportunities within live and simulated training. It must be noted that this paper should not be viewed as a criticism of the Canadian Army Doctrine and Training Centre (CADTC) or any other CAF training organization; it merely represents a training philosophy that could compliment CAF doctrine and current practices.

Jan Hodický , Dalibor Procházka, Fabian Baxa, Josef Melichar, Milan Krejcˇík, Petr Krˇížek, Petr Stodola, and Jan Drozd, “Computer Assisted Wargame for Military Capability-Based Planning,” Entropy 22, 861 (2020). 

Capability-based planning as an approach to defense planning is an almost infinitely complex engineered system with countless nodes and layers of interdependency, influenced by state and non-state diplomatic activities, information, military and economic actions creating secondary and third order effects. The main output of capability-based planning is the set of capability requirements needed to achieve the expected end-state. One revitalized qualitative technique that allows us to gain insights into unstructured and fuzzy problems in the military is wargaming—in its simplest form this involves manual wargaming. At the same time, there has been a push to bring computer assistance to such wargaming, especially to support umpire adjudication and move more generally towards full automation of human elements in wargames. However, computer assistance in wargaming should not be pushed, regardless of cost, towards quantitative techniques. The objective complexity of a problem often does not allow us to replicate the operational environment with the required fidelity to get credible experimental results. This paper discusses a discovery experiment aiming to verify the concept of applying a qualitative expert system within computer assisted wargaming for developing capability requirements in order to reduce umpire bias and risk associated with their decisions. The innovation here lies in applying system dynamics modelling and simulation paradigms when designing the theoretical model of capability development, which forms the core of the expert system. This new approach enables qualitative comparisons between different sets of proposed capability requirements. Moreover, the expert system allows us to reveal the effects of budget cuts on proposed capability requirement solutions, which the umpire was previously unable to articulate when comparing individual solutions by relying solely on his own knowledge. Players in the wargame validated the proposed concept and suggested how the study might be developed going forward: namely, by enabling users to define their own capabilities and not being limited by a predefined set of capabilities. 

Clifford Knopik, A Comparative Analysis of Video-Based Training and Game-Based Training on Information Security, doctoral dissertation, Colorado Technical University, September 2020.

Games are hypothesized to be an effective alternative for training than other methods. Prior research showed that learners often find training boring, and when they took training with games, they reported higher engagement, motivation, and a positive perception of the learning experience. The hypothesis for this study was that participants who take game-based information security awareness training would perform statistically significantly better than participants who took video-based training. One hundred participants were given a pretest and posttest with half of the participants using video-based information security awareness training, and the other participants using game-based information security awareness training. Conducting data analysis using IBM SPSS Statistics 24, it was discovered that the group receiving the video-based [games-based?] training performed significantly better on the posttest and had a higher mean score than the video-based training group. 

David Leece, “Training army officers in tactics,” United Service 71, 3 (September 2020).

The training of staff and regimental officers in common tactical doctrine (the ‘drills’) is essential to developing teamwork within formations, headquarters and units. But developing tactical thinking (the ‘skills’) is more difficult. A range of tools presented herein have been formulated by Western armies over two centuries to develop the skills and the drills separately and then merge them to create combat-ready formations.

Jeremiah McCall, “The Historical Problem Space Framework: Games as a Historical Medium,” Game Studies 20, 3 (September 2020).

Historical games need to be analyzed holistically as games rather than tasked to fulfill the functions of some other medium. The historical problem space (HPS) framework offers an approach to analyzing historical games more holistically as games rather than text, useful both for academic and educational historical analysis. It considers how all historical games present the past in terms of player agents with roles and goals that are contextualized within a virtual gameworld whose features enable and constrain player action. In response to this space, the player crafts strategies and makes choices. The purpose of this article is to provide a more detailed overview of the HPS framework and how it can be usefully employed to understand gamic histories. Ideally games scholars will be able to conduct their own analyses of historical games as historical problem spaces and educators use this framework to structure their classroom analyses of games.

Simon Miles, “The War Scare That Wasn’t: Able Archer 83 and the Myths of the Second Cold War,” Journal of Cold War Studies 22, 3 (Summer 2020).

Did the Cold War of the 1980s nearly turn hot? Much has been made of the November 1983 Able Archer 83 command-post exercise, which is often described as having nearly precipitated a nuclear war when paranoid Warsaw Pact policymakers suspected that the North Atlantic Treaty Organization (NATO) was using the exercise to launch a preemptive nuclear strike. This article challenges that narrative, using new evidence from the archives of the former Warsaw Pact countries. It shows that the much-touted intelligence effort to assess Western intentions and capabilities, Project RYaN, which supposedly triggered fears of a surprise attack, was nowhere near operational at the time of Able Archer 83. It also presents an account of the Pact’s sanguine observations of Able Archer 83. In doing so, it advances key debates in the historiography of the late Cold War pertaining to the stability and durability of the nuclear peace.

Vikram Mittal and Andrew Davidson, “Combining Wargaming With Modeling and Simulation to Project Future Military Technology Requirements,” IEEE Transactions on Engineering Management, early access September 2020.

The rapid growth and widespread availability of technology has allowed enemies to dynamically develop countermeasures to military systems. Therefore, it is imperative that military systems be designed to account for these countermeasures. As such, technology roadmapping should be a critical activity in the acquisition of defense systems. Technology roadmaps provide a strategic vision for a system that accounts for the operational context, including evolving needs and technology changes. However, the operational context can be difficult to predict. This article suggests using wargaming coupled with combat simulation to better understand the operational context to allow for testing and refining technology roadmaps. Wargaming requires teams to roleplay friendly and enemy units to determine how each side adapts with the implementation of a new military system. Computer-based simulations can then convert the qualitative results from the wargame into quantitative metrics that further inform the roadmap. A case study is presented for a technology roadmap associated with an armored exoskeleton. Wargaming forecasted the countermeasures implemented by the enemy and the associated responses. The wargame results were coupled with models to quantitatively forecast the change in the warfighter’s survivability and lethality. The wargame was then used to inform the technology roadmap.

Max Nelson, “Battling on Boards: The Ancient Greek War Games of Ship-Battle (Naumachia) and City-State (Polis),” Mouseion 17, 1 (2020).

Only two distinct board games (and their variants) are firmly attested among Greeks in the Classical period (fifth to fourth centuries bc). The first, eventually known as “Ship-Battle” (ναυμαχία), is first attested in the seventh century bc and was played (ordinarily) with ten counters and a die on a board with five parallel lines or a circle of ten spots. The second, known usually as “City-State” (πόλις), is first attested in the fifth century bc and was played with sixty counters (and possibly a die) on a board with a grid of lines. These two games were the first war games in the West (if not the world), preceding Chess by a millennium.

Jan Oliver Schwarz, “Revisiting Scenario Planning and Business Wargaming From an Open Strategy Perspective,” World Futures Review, 12, 3 (2020).

The key aim of Open Strategy is to open up the process of strategy development to larger groups within and even outside an organization. Furthermore, Open Strategy aims to include broad groups of stakeholders in the various steps of the strategy process. The question at hand is how can Open Strategy be achieved? What approaches can be used? Scenario planning and business wargaming are approaches perceived as relevant tools in the field of strategy and strategic foresight and in the context of Open Strategy because of their participative nature. The aim of this article is to assess to what degree scenario planning and business wargaming can be used in the context of Open Strategy. While these approaches are suitable, their current application limits the number of potential participants. Further research and experimentation in practice with larger groups and/or online approaches, or a combination of both, are needed to explore the potential of scenario planning and business wargaming as tools for Open Strategy.

Abbie Tingstad, Yuna Huh Wong, Scott Savitz, “How Can the Coast Guard Use Gaming?” RAND Homeland Security Operational Analysis Center, September 2020.

Games are widely used to better understand and prepare for a diverse set of challenges. Gaming is a generic term for a suite of structured methodological approaches that can qualitatively (and occasionally reinforced using quantitative data) support decisionmaking in many contexts. What makes a game a game is interactive, rule-based problem solving that includes adjudication of outcomes. Games can be played in formal or more relaxed settings and be supported by different communication tools, such as printed media, whiteboards, digital devices, and applications. Gaming is often associated with the U.S. Department of Defense, but many types of organizations outside of defense—governmental, commercial, nonprofit, and academic—develop and use gaming to support decisionmaking or other functions. The U.S. Coast Guard employs some approaches—largely informally—that fall under the umbrella of gaming. Conducting gaming more formally could help the service expand its analytic, training, and engagement tool kits. In this Perspective, the authors discuss what more the service might do to employ gaming, and why. In particular, the authors highlight the idea of deployable gaming: a low-cost, scalable, structured scenario-based approach that can help gather information, aid decisionmaking, and promote learning at different echelons within the service.

Haseeb Ur Rehman Warrich, Sahrish Jamil, Fazal Rahim Khan, “Behavioral Escalation: Video Games as a Tool of Hybrid War,” Global Mass Communication Review 5, 1 (Winter 2020).

Gaming industry in its short span of around forty years has evolved from a hobby to a huge economic industry. However, undeniably, incredible advancement in video game graphics has allowed this virtual world to manipulate and escalate its consumer’s behavior. Violent video games, according to Professor Robert Sparrow, have long been used for political contestation and social unrest. The study serves to analyze behavioral escalation through video games. This study has used Ian Bogust’s Procedural Rhetoric as a methodology to analyze video games. The results showed that video games are persuasive interactive medium that escalate behavior and have great potential to be used as a tool of hybrid warfare. Louis Jones stated that propaganda and unconventional warfare is not a new thing, it dates back to Greeks when they left wooden horse at Troy. Colin Gray, military strategist, described the future warfare as similar to the historical one but with modern means of technology. The new virtual means of warfare have not altered the nature of warfare but have developed its new ways. Combat games are more realistic in sense of its enhanced graphics and presentation. This study points towards the great potential in video games to work as a tool for Hybrid war 

Jorit Wintjes, “Analogue wargames in the time of social distancing: The ‘Long-Distance Kriefsspiel’,” Mars & Clio, 31 July 2020.

[Excerpt] Now, after our last wargame had ended before anything meaningful had happened (the French, who in an 1883-invasion-scare scenario had to push towards the east, having captured Liverpool, had barely managed to get their army corps out of the city), there was little in the way of post-mortem to prepare. We therefore decided to explore ways of running a traditional wargame in a “virtual”, if you want, way. I should stress that we did not try to develop a computer game; our research work is focussed on the history of the Prussian Kriegsspiel, and what we wanted was basically a long-distance Kriegsspiel.

We eventually adapted Prussian rules from the mid-1870s, a time when the original Kriegsspiel rules were expanded to care for larger operations – for an operational Kriegsspiel and organized a real-time simulation running for 12 days, in which each day would represent one day of fighting on the ground. The participants formed two army HQs and gave out orders each night at around 00:00 via email to the umpires; the umpires then moved forces and decided over combat, reporting combat results, reconnaissance information etc back to the participants by 18:00 the following day via email. This allowed the participants – we ran the simulation with two teams of young Bundeswehr officers – to carry on with their real- worldly tasks during the day and to meet in the evening to discuss the events of the simulation. In order to add period flavour, to increase immersion and to create the need for the participants to gather information from different sources the events were accompanied by faux newspaper articles which we published on a website accompanying the simulation.

Junfeng Zhang and Xue Qing, “Actor–critic-based decision-making method for the artificial intelligence commander in tactical wargames,” Journal of Defense Modelling and Simulation, online first September 2020.

In a tactical wargame, the decisions of the artificial intelligence (AI) commander are critical to the final combat result. Due to the existence of fog-of-war, AI commanders are faced with unknown and invisible information on the battlefield and lack of understanding of the situation, and it is difficult to make appropriate tactical strategies. The traditional knowledge rule-based decision-making method lacks flexibility and autonomy. How to make flexible and autonomous decision-making when facing complex battlefield situations is a difficult problem. This paper aims to solve the decision-making problem of the AI commander by using the deep reinforcement learning (DRL) method. We develop a tactical wargame as the research environment, which contains built-in script AI and supports the machine–machine combat mode. On this basis, an end-to-end actor–critic framework for commander decision making based on the convolutional neural network is designed to represent the battlefield situation and the reinforcement learning method is used to try different tactical strategies. Finally, we carry out a combat experiment between a DRL-based agent and a rule-based agent in a jungle terrain scenario. The result shows that the AI commander who adopts the actor–critic method successfully learns how to get a higher score in the tactical wargame, and the DRL-based agent has a higher winning ratio than the rule-based agent.

Review: Wojtowicz, Wargaming Experiences

Review: Natalia Wojtowicz, Wargaming Experiences: Soldiers, Scientists and Civilians (Amazon Fulfillment, 2020). 162+13pp. USD$39.00 pb.

In this interesting volume, Natalia Wojtowicz surveys the value of wagaming, key definitions, its application as a method of analysis and teaching, and the challenges of gaming non-kinetic issues and operations. Following this, the bulk of the volume discusses a series of wargames she designed and facilitated while working at the NATO Civil-Military Cooperation Center of Excellence.

All of these are political-military games, so those looking for insight as to how to wargame combat operations are best advised to look to works by Peter Perla and Phil Sabin. The issues addressed include Russian hybrid warfare challenges to the Baltic republics; civil-military liaison; tactical cooperation to address critical infrastructure vulnerabilities; the Battle of Mosul; a targeted assassination attempt using chemical weapons; and the Faroe Islands. In each case Wojtowicz discusses the purpose of the game, the problem to which it was responding, the approach and method adopted, game mechanics, and finally the game results.

The most useful part of this volume is the author’s well-structured explanation of why each game was designed and run the way it was. Assessment of the effectiveness of the games is largely anecdotal. Tighter editing would have strengthened the clarity and precision of her analysis. Overall, however, the volume provides useful insight into these sorts of games—and plenty of ideas from which aspiring serious game designers might borrow.
