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.
United States Air Forces Central Command
Concurrently with the amalgamation of Ninth Air Force formations in the Mediterranean with Twelfth Air Force, plans were afoot in Britain to devolve Eighth Air Force's medium bomber force to a separate command. This command was offered to Brereton, who accepted "with utmost eagerness", and the force was constituted, also as Ninth Air Force, on 16 October 1943.
