This United States Army publication, Field Manual FM 3-22 Army Support to Security Cooperation July 2023, provides doctrine for how the Army supports security cooperation (SC) to include security assistance and security force assistance and military engagement. Army forces support SC in many ways, but primarily through security force assistance. This manual will address security force assistance in detail while also covering the other ways that the Army supports SC.

FM 3-22 establishes context for Army missions by explaining how security cooperation activities are an integral component of multidomain operations, joint operations, and unified action. The principal audience for FM 3-22 is Army SC professionals within U.S. embassies, theater army planners, and echelons above brigade leaders and staffs. Trainers and educators throughout the Army will also use this manual.
