The ASA (M&RA) mission is firmly grounded in statute and regulation. Title 10 of the United States Code establishes the ASA (M&RA) as an entity and provides the mission foundation and states that the ASA (M&RA) has, as its principal duty, "the overall supervision of manpower and reserve component affairs of the Department of the Army." The Headquarters, Department of Army, General Order No. 3 provides further detailed descriptions of ASA (M&RA)'s responsibilities. Per General Order No. 3 (dated July 9, 2002), ASA (M&RA) serves as the Army's lead for civilian and military manpower policy, human resources, the review of soldier records, reserve/active component force structure policy, the Army-wide Equal Employment Opportunity Program and other critical matters as part of the Army leadership.

In fulfilling this mission, ASA (M&RA) will lead, shape, direct and manage Army activities, working in collaboration with our partners, within the human capital enterprise. Beyond the traditional components of human resource management, the ASA (M&RA) also has responsibility for providing oversight and direction to the Army's total force management, manpower and workforce management programs. This authority extends to all five components of the Army (i.e., Active, Guard, Reserve military, civilian and contractor). Additionally, the Secretariat's oversight and direction extends to training, readiness and mobilization policies, plans and programs affecting the Army (Active and Reserve Components) with a strong emphasis on reviewing all policies and programs pertaining to mobilization, demobilization and accessibility of the Reserve Components.

In all of these areas, ASA (M&RA) will provide proactive leadership, shape policy development and supervise policy execution.
