This United States Army manual, Army Techniques Publication ATP 3-57.50 Civil Knowledge Management October 2024, describes the techniques used by individuals, teams, and units of U.S. Army Civil Affairs (CA) forces, as well as planners of civil-military operations (CMO). The techniques herein are used when engaging other government agencies, indigenous populations and institutions, nongovernmental organizations, international organizations, and other military and nonmilitary entities in support of missions conducted by special operations forces or conventional forces. The principal audience for this publication is Army CA forces, noncommissioned officers, and officers who support joint and Army forces or who serve on staffs that support commanders and operations at all echelons. It is also an applicable reference to the civilian leaders of the U.S. interagency. ATP 3-57.50 is authoritative but not directive. It serves as a guide and does not preclude CA personnel or units from developing their own standard operating procedures. The techniques presented in this publication should not preclude CA forces from using their civilian-acquired skills, training, and experience to meet the challenges they face while conducting Civil Affairs operations and providing support to CMO. CA forces are trained, organized, and equipped to plan, execute, and assess the joint force commander's concept for CMO. CA forces provide essential capabilities that enable the commander by virtue of their area and linguistic orientation, cultural awareness, training in military-to-host nation advisory activities, and civilian professional skills that parallel common government functions.
