Conclusion
This chapter explains desertion in civil wars in terms of the complicated and counterintuitive dynamics of trust and mistrust at the heart of military units in times that tear countries apart. It bridges a long-running theoretical debate about how to understand people's motivations in civil wars. It also elaborates the grand causes of civil wars that matter through the interaction of combatants, which accepts that civil wars are both political and personal. The chapter pays attention to relations among combatants as key mechanisms driving armies forward and suggests a new theoretical extension that goes beyond interactions among armed groups. It focuses on signals, trust, and desertion that proposes arguments about when armed groups are likely to adopt the practices that are important for fostering trust and limiting desertion.
