The United States Army Installation Management Command (IMCOM) is a support formation of the United States Army responsible for the day-to-day management of Army installations around the globe. Army garrisons are communities that provide many of the same types of services expected from any small city. IMCOM is a major subordinate command of U.S. Army Materiel Command (AMC). IMCOM is headquartered at Fort Sam Houston.

The U.S. Army Materiel Command (AMC) is the primary provider of materiel to the United States Army. The Command's mission includes the management of installations, as well as maintenance and parts distribution. It was established on 8 May 1962 and was activated on 1 August of that year as a major field command of the U.S. Army. Lieutenant General Frank S. Besson, Jr., who directed the implementation of the Department of Army study that recommended creation of a "materiel development and logistics command", served as its first commander.
