Social protests are a feature of democracy in Latin America. When the police cannot handle them, governments, facing threats to their tenure, are tempted to order the armed forces to step in. The military, when ordered to deploy in counter-protest operations, exhibits behaviors ranging from defiance to conditional and full compliance. The article investigates the sources of variation in military responses to mass protests, leveraging a small-n comparative analysis and a diverse case selection strategy. It draws on qualitative evidence from Bolivia, Peru, and Ecuador, democracies with a history of protests. It finds that a combination of the judicial risks soldiers assume if they repress, professional mission preferences, and social identity between the military and the protesters are the most compelling explanations for military responses.
