Back in July, we mentioned Ben Connable’s presentation on “the will to fight” at the Connections US wargaming conference. Now we are pleased to post links to the two recently-released RAND studies on the military will to fight (Connable et al, 2018) and national will to fight (McNerney et al, 2018):
Will to fight may be the single most important factor in war. The U.S. military accepts this premise: War is a human contest of opposing, independent wills. The purpose of using force is to bend and break adversary will. But this fundamental concept is poorly integrated into practice. The United States and its allies incur steep costs when they fail to place will to fight at the fore, when they misinterpret will to fight because it is ill-defined, or when they ignore it entirely. This report defines will to fight and describes its importance to the outcomes of wars. It gives the U.S. and allied militaries a way to better integrate will to fight into doctrine, planning, training, education, intelligence analysis, and military adviser assessments. It provides (1) a flexible, scalable model of will to fight that can be applied to any ground combat unit and (2) an experimental simulation model.
What drives some governments to persevere in war at any price while others choose to stop fighting? It is often less-tangible political and economic variables, rather than raw military power, that ultimately determine national will to fight. In this analysis, the authors explore how these variables strengthen or weaken a government’s determination to conduct sustained military operations, even when the expectation of success decreases or the need for significant political, economic, and military sacrifices increases.
This report is part of a broader RAND Arroyo Center effort to help U.S. leaders better understand and influence will to fight at both the national level and the tactical and operational levels. It presents findings and recommendations based on a wide-ranging literature review, a series of interviews, 15 case studies (including deep dives into conflicts involving the Korean Peninsula and Russia), and reviews of relevant modeling and war-gaming.
The authors propose an exploratory model of 15 variables that can be tailored and applied to a wide set of conflict scenarios and drive a much-needed dialogue among analysts conducting threat assessments, contingency plans, war games, and other efforts that require an evaluation of how future conflicts might unfold. The recommendations should provide insights into how leaders can influence will to fight in both allies and adversaries.
The former study in particular examines the way in which wargames do or do not model “will to fight,” and suggests some key lessons for future wargame design:
Adding will to fight changes combat simulation outcomes
- Most U.S. military war games and simulations either do not include will to fight or include only minor proxies of it.
- However, the simulated runs performed for this report showed that adding will-to-fight factors always changes combat outcomes and, in some cases, outcomes are significantly different.
- U.S. Army and Joint Force should adopt a universal definition and model of will to fight.
- Include will to fight in all holistic estimates of ground combat effectiveness.
- War games and simulations of combat should include will to fight.
