Joseph Carroll (DIA)
When the U.S. Air Force was established as a separate executive department under the National Security Act of 1947, Secretary of the Air Force W. Stuart Symington, requested FBI Director J. Edgar Hoover to loan General Carroll to the services to organize a U.S. Air Force agency for investigative and counterintelligence functions. He organized and directed this new organization, the AFOSI, along the lines of the FBI rather than the U.S. Army's Criminal Investigation Command (USACIDC or CID). General Carroll was tendered a commission as a colonel, U.S. Air Force Reserve, January 12, 1948. He was ordered to active duty in the grade of brigadier general May 6, 1948, and promoted to major general August 11, 1950.
Aviation Cadet Training Program (USAAF)
In September 1947, the U.S. Army Air Forces became a separate and independent service, renamed the United States Air Force (USAF). At the time, the newly created Air Force had no service academy of its own yet (the USMA and USNA had options for their cadets and midshipmen, respectively, to become USAF officers). Separate Air Force ROTC and Officer Candidate School (later retitled Officer Training School) programs were still being established. The Aviation Cadet Training Program continued to remain as a principal source of the Air Force's pilots and navigators and they wore the same basic uniform as Air Force officers.
