The purpose of this article is to outline a model of cohesion useful for assessing military arbitration of revolutions. Current approaches to the study of revolution are not able to adequately integrate the military into their analysis. To remedy the lack of appropriate tools, this article outlines a model of cohesion that may be useful for conceptualizing and examining the behavior of military forces during domestic political crises. Building on the so-called standard model of cohesion, the article develops a cohesion-coordinated action model that incorporates a structural social cohesion element and a voluntarist-coordinated action element, both of which also capture the relations and interactions between the military, the regime, and the opposition. It thereby fulfils the requirements that a model must possess but where other approaches fall short. The article concludes by outlining how this model can be used in further research in order to advance the study of the military’s role in revolutions.
