Activated on 24 October 2006, the Installation Management Command consolidated three existing organizations—the Installation Management Agency (IMA), Community and Family Support Center, and Army Environmental Center—to streamline the support mission and provide uniformity of service to over 180 Army installations across the globe.

Its creation was spurred in part by the success experienced by the IMA, which had been formed in 2002 to remove the burden of managing Army installations spread across fifteen major command by using an enterprise approach to eliminate inefficiencies. Utilizing the same enterprise approach, the Installation Management Command system yielded immediate and significant savings: in Fiscal Year 2006, the Army fulfilled its installation management mission for a whopping $4.5 billion less than in 2003.

Headquartered at Fort Sam Houston, Texas, the Command coordinates the efforts of over 75,000 professionals. Since 2019, the IMC has been a major subordinate command of Army Materiel Command.
