Author Description

Army Doctrine Publication (ADP) 3-28 describes a doctrinal foundation for the Army's contribution to defense support of civil authorities (also called DSCA) (see figure 1, page iv, for a graphical overview). 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.

Commanders at all levels ensure their Soldiers operate in accordance with the law of war and the rules of engagement. (See Field Manual [FM] 27-10.)
