FM 3-24 (Counterinsurgency)

FM 3-24, also known as Counterinsurgency (COIN) doctrine, provides military guidance on how to address insurgencies—where armed groups challenge governments through unconventional tactics. It emphasizes combining military actions with political, economic, and social efforts to win public support and address root causes. The manual advocates for understanding local cultures, building trust with communities, and employing precise, indirect approaches rather than brute force alone. The goal is to weaken insurgents by empowering legitimate governments and communities, creating stable environments where insurgencies cannot thrive.
