U.S. Army Installation Management Command (IMCOM)

IMCOM is responsible for management of 75 installations world-wide. IMCOM delivers and integrates base support to enable readiness for a self-reliant and globally-responsive All Volunteer Army.

Army installations are communities that provide many of the same types of services expected from any small city. Fire, police, public works, housing and child care are just some of the things IMCOM does in Army communities every day. The command focus is on sustainability to address present and future needs while strengthening community partnerships that improve our force generation support capabilities to organize, equip, train and deploy Soldiers as part of joint forces.

Joint Base Myer-Henderson Hall is one of the 75 installations in the Atlantic Region. The Atlantic Region was formed in August 2011 when IMCOM’s Northeast and Southeast regions merged. It oversees base operations and installation management including public works and family support programs at 38 locations which include 22 garrisons, 12 depots, and four Army support activities to ensure readiness of Soldiers, families and military units.

IMCOM provides Soldiers, civilians and their Families with a quality of life commensurate with the quality of their service. Our professional workforce strives to deliver on the commitments of the Army Family Covenant, honors the sacrifices of military Families and enables the Army force generation cycle.

IMCOM’s Mission: IMCOM will synchronize, integrate and deliver installation services and sustain facilities in support of Senior Commanders in order to enable a ready and resilient Army.
