Headquarters, U.S. Army
Installation Management Command, Pacific (IMCOM-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, Hawaii, has garrison installations in Hawaii, Alaska, Japan and Korea.
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 the 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 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 in Texas.

U.S. Army Garrison-Hawaii (USAG-HI)
USAG-HI reports directly to IMCOM-Pacific.
USAG-HI operates 22 Army installations and sub-installations in Hawaii, and provides quality installation management service and logistical support for more than 95,000 Army and civilian personnel assigned to Fort Shafter, Tripler Army Medical Center, Schofield Barracks, Wheeler Army Airfield, the Pohakuloa Training Area, and other sub-installations located throughout the islands of Oahu and Hawaii. Although its communities are geographically separate, the garrison is organized, staffed and operated under the single post concept.
The headquarters for USAG-HI is located on Wheeler Army Airfield, while the adjacent Schofield Barracks serves as home to the 25th Infantry Division.
Centrally located on Oahu, on the eastern slope of the Waianae Mountain Range, Schofield Barracks is named in honor of Lt. Gen. John M. Schofield, who, in 1872, recognized the strategic importance of Oahu to the defense of the United States. Construction was begun on the barracks in 1909.
Today, Schofield’s training areas and cantonment area occupies more than 18,000 acres. Schofield Barracks supports approximately 65,000 Soldiers, civilians, contractors and family members.
Fort Shafter, located outside Honolulu, has been home to the senior Army headquarters in Hawaii for almost a century. Principal tenants include USARPAC, the 8th TSC, the 311th Signal Command, the 94th AAMDC, and the Army Corps of Engineers – Pacific Ocean Division.
When the post opened in 1907, it was named for Maj. Gen. William R. Shafter (1835-1906), who led the U.S. expedition to Cuba in 1898. Tripler Army Medical Center, Fort DeRussy and the U.S. Army Museum in Waikiki are also located nearby.
Fort Shafter supports nearly 30,000 Soldiers, civilians, contractors and family members. Today, Fort Shafter remains the focal point for command, control and support of Army forces in the dynamic Asia-Pacific region.
USAG-Pohakuloa, also known as Pohakuloa Training Area, is located on the Big Island of Hawaii. It is the major training area for USARPAC and is used extensively by USPACOM and Reserve forces in the Pacific for joint and combined training exercises. It is also the largest U.S.-owned training area in the Pacific that permits the effective integration of fire and maneuver in joint and combined-arms operations.
