ARMY - AR 10-87
Army Commands, Army Service Component Commands, and Direct Reporting Units
|Publication Date:||11 December 2017|
This regulation prescribes Army Commands (ACOMs), Army service component commands (ASCCs), and direct reporting units (DRUs) missions, functions, and command and staff relationships within the Department of the Army (DA).
a. Institutional Force. The institutional force ensures the readiness of all Army forces and consists of Army organizations whose primary mission is to generate, prepare, and sustain the operating forces of the Army. Therefore, the institutional force remains under the direction and control of DA.
b. Geographic combatant command. The Army's designation for an ASCC assigned to a geographic combatant command (CCMD) is the theater Army. This regulation will not infringe on the combatant command authority vested, by law, in combatant commanders (CCDRs) or alter the command relationships and authorities specified by the Secretary of Defense (SECDEF). ASCCs will address changes in force assignment with their supported CCMD in accordance with procedures specified by the SECDEF. This regulation applies to the following Army organizations:
c. Army commands.
(1) U.S. Army Forces Command (FORSCOM).
(2) U.S. Army Training and Doctrine Command (TRADOC).
(3) U.S. Army Materiel Command (AMC).

(1) Army General Orders provide organization missions and command authorities. AR 10-87 supplements the Army General Orders and describes organization functions and command and staff relationships.
(2) The ASCCs exercise mission command under the authority and direction of the CCDRs to whom they are assigned and in accordance with the policies and procedures established by the SECDEF. In the event of a discrepancy between this regulation and the policies or procedures established by the SECDEF, the SECDEF policies or procedures take precedence.
(3) Per Section I of the Global Force Management Implementation Guidance, the Secretaries of the military departments may operate as "Force Providers" of Service retained forces, with discrete authorities specifically delegated by the SECDEF. Where appropriate, this regulation codifies how the Secretary of the Army (SECARMY) delegates these discrete authorities to the commanders of military service forces.
(4) Administrative control (ADCON).
(a) ADCON is not a command relationship. ADCON is direction or exercise of authority over subordinate or other organizations in respect to administration and support.
(b) ADCON is synonymous with administration and support responsibilities identified in Title 10, United States Code (10 USC). This is the authority necessary to fulfill military departments' statutory responsibilities for administration and support.
(c) The SECARMY's 10 USC responsibilities are exercised through ADCON. ADCON includes organization of Service forces, control of resources and equipment, personnel management, unit logistics, individual and unit training, readiness, mobilization, demobilization, discipline, and other matters not included in the operational missions.
(d) ADCON may be delegated to and exercised by commanders of Service forces assigned to a CCDR at any echelon at or below the level of Service component command. ADCON is subject to the command authority of CCDRs. ADCON may be delegated to and exercised by commanders of Service commands assigned within Service authorities. Service commanders exercising ADCON will not usurp the authorities assigned by a CCDR having combatant command authority over commanders of assigned Service forces.
(e) Normally, ASCCs exercise ADCON responsibilities for Army forces assigned to the CCDR within their area of responsibility (AOR). In some cases, an ACOM or DRU may share ADCON responsibilities with the ASCC for assigned organizations deployed to an AOR in order to more efficiently and effectively support globally deployed Army forces.
(f) CCDRs exercise combatant command authority over operational Army forces assigned to the CCDR. The CCDR normally delegates operational control (OPCON) of Army forces to the ASCC.
(g) Subject to applicable law, regulation, and policy, the allocation of authorities and responsibilities pertinent to the exercise of shared ADCON should be documented in appropriate agreements/understan
(5) ARCYBER exercises directive authority for cyberspace operation authority (as delegated by SECDEF and U.S. Cyberspace Command (USCYBERCOM)). ACOMs, ASCCs, DRUs, and all other Army organizations will comply with cyberspace operations (CO)-related orders and directives issued by ARCYBER (or designated delegates). A mutual support relationship exists between ARCYBER and ACOMs, ASCC, DRUs, and all other Army organizations to secure, operate, and defend the Department of Defense Information Network (DODIN), maintain freedom of action, and deny the same to our adversaries.
(6) The DRUs will exercise authorities as specified in regulation, policy, delegation, or other issuance.
(7) The U.S. Army Reserve Command (USARC) performs 10 USC support to units with Army Reserve unit identification codes (UICs). Units with Regular Army UICs receive 10 USC support from their respective Army organization. Units with Army National Guard (ARNG) UICs receive premobilization support from Headquarters, Department of the Army (HQDA) through the National Guard Bureau (NGB) under Title 32 USC.
