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).

Four types of command authority can be distinguished:[1] The sustainment function for 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.
