Headquarters, U.S. Army Installation Management Command, Pacific
The Army activated the Installation Management Command Oct. 24, 2006, to consolidate and strengthen installation support services to soldiers, civilians and their families. The Pacific Region, headquartered at Fort Shafter, has garrison installations in Hawaii, Alaska, Japan, Korea and Kwajalein.
IMCOM-Pacific replaces the former agency and marks the next step in the evolution of Army installation management.
IMCOM evolved out of the Installation Management Agency, established in 2002 to reduce bureaucracy and apply a uniform business structure to manage U.S. Army installations worldwide. IMCOM continues to oversee such facets of installation management as construction, family care, food management, environmental programs, well-being, public works and installation funding.
IMCOM presently has more than 100 installations in four regions: two regions in the continental United States, one region in Europe and one in the Pacific.
IMCOM oversees a standardization process that provides soldiers, civilians and families a consistent quality of services at all installations. It also streamlines how installations receive money and ensures that installation funds are used for installation services.
By assuming installation management duties, IMCOM relieves warfighters and mission commanders of garrison tasks so they can focus on training and missions.
The full authority of command is vital to effectively direct the vast resources necessary to support troop deployments while meeting the needs of their families. Consolidating the installation management structure under IMCOM optimizes resources, protects the environment and enhances the well-being of the Army community.
IMCOM provides fast, efficient and agile support to commanders in the performance of their tactical and strategic missions.
The Installation Management Command is headquartered on Fort Sam Houston, Texas.
