Between March 1943 and September 1946 Greensboro was home to the country's largest military base within the limits of
Basic Training Center No. 10 opened on 1 Mar. 1943. Trainees endured from four to eight weeks of intensive training in weapons, drill, physical fitness, and chemical warfare. Airmen then left for advanced training at other bases prior to assignment in combat theaters around the world. Among the 87,500 trainees who passed through the facility were members of the Women's Air Corps, whose six-week stints trained them in a variety of administrative and support fields. The center also trained African American airmen, a fact that displeased some of Greensboro's citizens. Black servicemen were segregated, and despite their repeated requests for equal treatment as military personnel, their training was restricted to support services and labor battalions.
The focus of the center shifted in 1944, when it became the AAF's principal Overseas Replacement Depot (ORD) on the East Coast; it served in this capacity until the end of the war. By 1 May, with trained airmen available in sufficient numbers, ORD processed personnel for rotation to overseas combat operations. In August 1945 the ORD was also designated AAF Redistribution Station No. 5 and assumed responsibility for reassigning returning soldiers to other posts in the United States.
In September 1945, the ORD became a major discharge center and processed thousands of returning veterans. When it closed in September 1946, the Bessemer Improvement Company bought 433 acres of the ORD land, along with nearly half of the buildings, and opened the area to residential development.
