United States Army Sustainment Command


United States Army Sustainment Command 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.
Four types of command authority can be distinguished:
  1. COCOM - combatant command: unitary control
  2. ADCON - administrative control of the command function of "obtaining resources, direction for training, methods of morale and discipline"
  3. OPCON - operational control of sustainment, a command function, in this case, embodied in an Army Field Support Brigade
  4. TACON - tactical control of sustainment, as embodied in a Contracting Support Brigade
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. In the case of geographically remote locations, logistics can be an additional constraint to be solved, while still providing sustainment to the Army soldier.
