The Base Closure and Realignment Commission has approved the relocation of a Fourth Infantry Division combat brigade and headquarters team to Fort Carson, Colorado.
The change was part of Defense Secretary Donald Rumsfeld's original proposal to shuffle the Pentagon's brigade combat organization.
That would return the division to the base where it was headquartered from 1970 to 1996.
Killeen, Texas-based Fort Hood would still have five combat teams, and an estimated troop strength of about 41,000 even without the division.
Pentagon officials argued Fort Hood lacked enough facilities and land to support six heavy brigades and other units stationed there.
But Texas officials claimed the Defense Department overlooked more than 37,000 acres of newly available land, and failed to completely calculate the cost of training at Fort Carson.
