# 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.

### Petroleum, Oil and Lubricant Supply Company (PSC)

A PSC is charged with receiving, storing and distributing petroleum, oil and lubricant (POL) products. Each PSC is composed of three platoons which contain Area Support Sections (which can store and receive 360,000 gallons of POL) and Distribution Sections (transporting 146,250 gallons of POL daily) and can operate up to six hot refueling sites. 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.

### Quartermaster Field Service Company (FSC)

Known also as the SLCR Company, the FSC is a Quartermaster Corps unit designed to provide shower, laundry and clothing repair service for approximately 21,000 soldiers.

It can also conduct delousing as deemed necessary by the medical authority.

### Support Maintenance Company (SMC)

An SMC provides tactical and operational field maintenance support for all units within the sustainment brigade's area of operation. It consists of a company headquarters providing command and control for cellular platoons, modules teams performing system repair and replacement and return to user operations. Up to 10% of an SMC's overall strength can consist of civilian augmentation as needed.

### Component Repair Company (CRC)

The CRC provides support to the theater supply system, conducting component repair and return of repaired item to the supply system. The CRC operates anywhere along the distribution network, beginning at the national source of repair. The unit can attach platoons, sections and teams to an SMC or other sustainment units.

### Collection & Classification Company (C&C Co)

A C&C Co establishes and operates collection and classification facilities for the receipt, inspection, disassembly, preservation and disposition of both domestic and foreign Class VII and IX materiel.

C&C teams are often attached forward, at the discretion of the Distribution Management Center.

### Quartermaster Collection Company - Mortuary Affairs (MA)

This company coordinates the evacuation of remains and personal effects to the Theater Mortuary Evacuation Point (TMEP) and can operate a Mortuary Affairs Decontamination Control Point (MADCP) when supported by a chemical decontamination company.
