The U.S. Army relies on commercial contractors to provide non-combat support services to deployed U.S. DOD forces and other government agencies. Contractors must be capable of mobilizing thousands of personnel, support equipment, and supplies virtually anywhere in the world on very short notice.  The nature of the services includes providing logistics, base-camp construction, housing, transportation, fuel, meals, laundry, and recreation. Outsourcing of these services enables the military to focus on its core mission.
