Alternate Title: Army Doctrine Publication 3-28: Defense Support of Civil Authorities
"Army Doctrine Publication (ADP) 3-28 describes a doctrinal foundation for the Army's contribution to defense support of civil authorities (also called DSCA) […]. ADP 3-28 focuses on the operational Army battalions, brigades, division headquarters, and Army Service component headquarters conducting DSCA, with support from the generating force. A corresponding Army doctrine reference publication (ADRP) elaborating on the principles in ADP 3-28 is expected to replace Field Manual (FM) 3-28. The principal audience for ADP 3-28 is all members of the profession of arms. Commanders and staffs of Army headquarters serving as joint task force or multinational headquarters should also refer to applicable joint or multinational doctrine concerning the range of military operations and joint or multinational forces. Trainers and educators throughout the Army will also use this publication. Commanders, staffs, and subordinates ensure their decisions and actions comply with applicable United States, international, and, in some cases, host-nation laws and regulations. Commanders at all levels ensure their Soldiers operate in accordance with the law of war and the rules of engagement. ADP 3-28 applies to the Active Army, Army National Guard/Army National Guard of the United States, and United States Army Reserve unless otherwise stated."
