FORSCOM has nearly 200,000 Soldiers stationed nationwide. This number includes three Army corps—I Corps at Fort Lewis, Wash.; III Corps at Fort Hood, Texas; and XVIII Airborne Corps at Fort Bragg, N.C. FORSCOM also has eight divisions, multiple brigade combat teams and a full range of other combat, combat support and combat service support units. First Army at Fort Gillem reports to FORSCOM. It is responsible for the training, readiness, mobilization and deployment support for Army National Guard and Army Reserve units in FORSCOM. It also executes FORSCOM missions within the continental United States and Puerto Rico. Army Reserve units are part of the federal force and make their primary contribution to FORSCOM's combat power by providing support specialties such as medical, civil affairs, public affairs, transportation, maintenance and supply. As such, the Reserve accounts for about 45 percent of the Army's total combat service support strength and about 30 percent of the total combat support units. Many Reserve units are designated to deploy early for contingency operations worldwide. The Army National Guard provides FORSCOM a balanced force of eight National Guard combat divisions, 32 separate brigades and extensive supporting units. The current FORSCOM Army National Guard strength is about 350,000 Soldiers. Mobilizing the Army National Guard into active federal service would bring the total strength of FORSCOM to nearly two-thirds of the Army's combat ground forces.

It commands all U.S. Army Reserve conventional forces in the continental U.S. and Puerto Rico. Units in the Army Reserve have a warfight focus on combat support and combat service support missions for the Total Army and include medical, legal, civil affairs, chemical warfare, transportation, engineering and military police. The USARC was established in October 1990 as a major subordinate command of the U.S. Army Forces Command (FORSCOM). In September 1998, the USARC moved from leased facilities into their headquarters building on Fort McPherson. In 2007, the USARC transferred from reporting to FORSCOM to reporting directly to DA. Approximately 900 civilians, contractors and Soldiers work at the headquarters. The USARC provides command, control and support for all Army Reserve troop units in the continental United States. The USARC also ensures the readiness of its force and prepares more than 2,000 Troop Program Units under its command to mobilize in support of
