The United States Army Sustainment Command (ASC) is the primary provider of logistics support to units of the United States Army. It is a major subordinate command of United States Army Materiel Command (AMC). ASC is headquartered at Rock Island Arsenal in Illinois.

History

On Wednesday, June 10 2026 at the Rock Island Arsenal, a ceremony was held of the Joint Munitions Command colors casing as they become part of United States Army Sustainment Command.

Command authority and the Army Sustainment Command

Four types of command authority affect the United States Army's forces (some apply to the Army Sustainment Command):Dr. Christopher R. Paparone (November–December 2007) COCOM, ADCON, OPCON, TACON, Support – Do You Know the Difference? Army Logistician another copy can be found here Administrative control (ADCON) – a relationship where a unit obtains resources, direction on training, methods of morale and discipline, and other functions from a designated higher headquarters (e.g., the Army Transportation Command—distinct from the Army Sustainment Command—is under the ADCON of the Army Materiel Command.) Combatant command (COCOM) – the control over military operations, joint training, and logistics matters of a service branch component to a U.S. Department of Defense unit. The Army Sustainment Command—not designated an Army service component command to a unified combatant command (or other joint unit)—is not affected by COCOM authority. (An example of a unit under COCOM authority is the Army Transportation Command. It is under the ADCON of the Army Materiel Command, while under the COCOM of the U.S. Transportation Command, due to it being assigned as its Army service component command.) Operational control (OPCON) – a relationship where a higher headquarters, other than the ADCON-providing headquarters, controls a unit's tasks and upward reporting structure. Typically, operational control is applied to a unit on deployment to a different region, or, on a special mission. In the Army Sustainment Command, the Army field support brigades are assigned to ASC, but are operationally controlled by a theater sustainment command or an expeditionary sustainment command under an Army service component command. (Another example of operational control is when OPCON is held by a unified combatant command over its assigned service branch units. For example, the U.S. Central Command may hold OPCON over the units in I Marine Expeditionary Force on a rotational deployment). Tactical control (TACON) – a lower level of OPCON.

The sustainment of an Army installation, such as Fort Bliss and White Sands Missile Range, two contiguous but administratively separate military installations, can be tailored to the situation. In the case of geographically remote locations, logistics can be an additional constraint.Megan Gully (September 27, 2018) How Army logistics help Soldiers maintain strategic advantage
