Combat Sustainment Support Battalion

A Combat Sustainment Support Battalion (CSSB) is a combat service support battalion of the United States Army. A CSSB can be attached to a sustainment brigade to support the brigade combat teams and support brigades assigned to a corps with maintenance, transportation, supply, field services, and distribution functions. The CSSB is task-organized with the subordinate units necessary to carry out its mission.

Composition
The CSSB is a modular organization that is tasked to support between one and three brigade-sized formations, consisting of a command group and staff, and any combination of the following support companies:

Transportation Units
Units of the Transportation Corps provide for the movement of personnel and matériel (minus medical supplies) in support of Army operations. Those that are assigned under the control of a CSSB include Motor Truck Companies, Movement Control Battalions and/or Movement Control Teams.

Quartermaster Support Company (QSC)
The QSC is considered the workhorse of the CSSB, providing food service and supervision/common tools for unit level maintenance with between two and four subsistence or area support platoons. With a typical task organization of one subsistence and three area support platoons (the latter of which can operate at two different locations simultaneously each), the QSC can receive, store and issue a cumulative 94 short tons of Class I supplies a day (including refrigeration) and 204 short tons of Class II, III (P), IV and IX supplies.

A PSC equipped for tactical sustainment support can store 1.8 million gallons of POL and receive/issue 600,000 gallons daily; when equipped for operational sustainment support it can store 5 million gallons and receive/issue 900,000 gallons daily. A PSC may also be assigned a POL Quality Analysis Team to conduct quality evaluation of POL products.

An SMC provides tactical and operational field maintenance support for all units within the sustainment brigade's area of operation.
