Commanders
Current commander	Major General Steven Shapiro[1]

Four types of command authority can be distinguished:[2]

1. COCOM - combatant command: unitary control (not further delegatable by the combatant commander CCDR)
2. ADCON - administrative control of the command function of "obtaining resources, direction for training, methods of morale and discipline"[2]
3. OPCON - operational control of sustainment, a command function, in this case, embodied in an Army Field Support Brigade (AFSB)
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.[3] In the case of geographically remote locations, logistics can be an additional constraint to be solved, while still providing sustainment to the Army soldier.[4]
