Fort Hood is a United States Army post located in Killeen, Texas. Named after Confederate General John Bell Hood, it is located halfway between Austin and Waco, about 60 miles (97 km) from each, within the U.S. state of Texas. The post is the headquarters of III Corps and First Army Division West and is home to the 1st Cavalry Division and 3rd Cavalry Regiment, among others. It is one of the U.S. Army installations named for Confederate soldiers to be renamed by the Commission on the Naming of Items of the Department of Defense that Commemorate the Confederate States of America or Any Person Who Served Voluntarily with the Confederate States of America.
Its origin was the need for wide-open space to test and train with World War II tank destroyers. The War Department announced the location in January 1942, and the initial completion was set for that August. As originally constructed, Fort Hood had an area of 158,706 acres (64,226 ha), with billeting for 6,007 officers and 82,610 enlisted personnel. The main cantonment of Fort Hood had a total population of 53,416 as of the 2010 U.S. Census. Fort Hood is the most populous U.S. military installation in the world. The main business area is in Bell County, with the training countryside area of the post in Coryell County.
