History. This publication is a major revision.

Summary. This publication continues to establish Army headquarters to more effectively support a leaner, more agile modular force. It distinguishes the differences in scope and responsibility of organizations. It recognizes the Armywide role and multidiscipline functions of the Army commands; the theater Army as an Army service component command reporting directly to Department of the Army and serving as the Army's single point of contact for combatant commands; and the direct reporting units as providing broad, general support to the Army in a normally single, unique discipline not otherwise available elsewhere in the Army. It identifies each organization's missions, functions, and command and staff relationships with higher and collateral headquarters and agencies.

Applicability. This regulation applies to the Regular Army, the Army National Guard/Army National Guard of the United States, and the U.S. Army Reserve, unless otherwise stated.

Proponent and exception authority. The proponent of this regulation is the Deputy Chief of Staff, G-3/5/7. The proponent has the authority to approve exceptions or waivers to this regulation that are consistent with controlling law and regulations. The proponent may delegate this approval authority, in writing, to a division chief within the proponent agency or its direct reporting unit or field operating agency, in the grade of colonel or the civilian equivalent. Activities may request a waiver to this regulation by providing justification that includes a full analysis of the expected benefits and must include formal review by the activity's senior legal officer. All waiver requests will be endorsed by the commander or senior leader of the requesting activity and forwarded through their higher headquarters to the policy proponent. Refer to AR 25-30 for specific guidance.

Army internal control process. This regulation contains internal control provisions in accordance with AR 11-2 and identifies key internal controls that must be evaluated (see appendix B).

Supplementation. Supplementation of this regulation and establishment of command and local forms are prohibited without prior approval from Deputy Chief of

Staff, G-3/5/7 (DAMO-SSP), 400 Army Pentagon, Washington DC 20310-0400.

Committee management. AR 15-1 requires the proponent to justify establishing/continuing committee(s), coordinate draft publications, and coordinate changes in committee status with the Office of the Administrative Assistant to the Secretary of the Army, Department of the Army Committee Management Office (AARP-ZA), 9301 Chapek Road, Building 1458, Fort Belvoir, VA 22060-5527. Further, if it is determined that an established "group" identified within this regulation, later takes on the characteristics of a committee, as found in the AR 15-1, then the proponent will follow all AR 15-1 requirements for establishing and continuing the group as a committee.

Distribution. This regulation is available in electronic media only and is intended for the Regular Army, the Army National Guard/Army National Guard of the United States, and the U.S. Army Reserve.
