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.
Military Air Transport Service
When the United States Air Force was established as a separate service in 1947, the Air Transport Command was not established as one of its major commands. The ATC commander and his staff took it upon themselves to convince the new civilian leadership of the newly created Department of Defense (DOD) (and Secretaries of the Army and Air Force) that ATC had a mission. They seized upon testimony by former I Troop Carrier Command commander Major General Paul L. Williams that the Air Force should have a long-range troop deployment capability, and began advocating that ATC transports could be used to deploy troops. Williams had been pressing for the development of a long-range troop carrier airplane when he made his statement.
