The Army will relocate the headquarters of one of its largest Army commands, the U.S. Army Materiel Command (AMC), to Fort Belvoir, VA. The first contingent of employees could be moving into an existing building by February. Maj. Gen. Richard Hack, AMC Chief of Staff, stated the primary reasons for the move are increased security, reduction in leased space costs, and enhanced efficiency. Hack also emphasized, "The events of September 11th underscore our need for security and increased safety." The plan calls for moving the rest of the command into facilities made available through the erection of manufactured modular buildings by fall of next year. Approximately 1,100 civilian employees, soldiers and contractors assigned to AMC will eventually move to Fort Belvoir. The AMC's currently leases its headquarters in a 549,336-square-foot building at 5001 Eisenhower Ave. in Alexandria, VA. Fort Belvoir offers a suitable site with in-depth military security, and the relocation will have minimal impact on employees due to its proximity to the current location. The Army Materiel Command is the only four-star headquarters in the Army not currently on a military installation.
