Sustainment Command (Expeditionary)

An expeditionary sustainment command (ESC), stylized "Sustainment Command (Expeditionary)", is a logistics headquarters in the United States Army. The concept of sustainment is as follows: the provision of logistics, financial management, personnel services, and health service support necessary to maintain operations until a mission is successfully completed.^[1]

An expeditionary support command is organized with one or more sustainment brigades, transportation brigades, or movement control battalions (for theater opening, theater distribution, or theater closing operations).^[2] An ESC holds command and control over all assigned and attached units, as directed by the theater sustainment command.

In 2019, the Army had three active component and six reserve ESCs, which totaled nine in the Army. Each active ESC is located together with a corps.^[3] A brigadier general leads an expeditionary sustainment command.

An ESC is made up of 74 military occupational specialties (MOS) and 40 branches and sections. As such, it is important to communicate well during planning, as to allow leaders and soldiers to identify tasks for military occupations. This guideline applies to joint training events as well.^[4]
