There were as many as 31 stateside OCS programs during World War II and several overseas in the European and Pacific Theaters.
During the Korea War there were nine (9) programs. By 1954 most of them had closed, but by 1967 there were (9) branch OCS programs operating again.
In January 1973 only three were left (Infantry, Artillery and WAC). After the Artillery OCS closed in July 1973 and the WAC OCS merged with the Branch Immaterial OCS at Fort Benning in 1976, there was only one Federal U.S. Army Officer Candidate School. Click on links below for information about Army branch OCS programs from the past. We currently have 200 pages of information about 25 OCS Programs from 1941 to the present. (This is a work in progress).
The U.S. Army Air Forces (AAF) Cadet Pilot Training During World War II was not an Army OCS program. However many Army OCS graduates later earned their Wings along side Aviation Cadets who earned their Wings and Commissions in the AAF Cadet Pilot Training Program.
