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 Section, U.S. Signal Corps
The Aviation Section, Signal Corps was created by the 63rd Congress (Public Law 143) on 18 July 1914 after earlier legislation to make the aviation service independent from the Signal Corps died in committee. From July 1914 until May 1918 the aviation section of the Signal Corps was familiarly known by the title of its administrative headquarters component at the time, seen variously as the Aeronautical Division, Air Division, Division of Military Aeronautics, and others. For historic convenience, however, the air arm is most commonly referred to by its official designation, the Aviation Section, Signal Corps (ASSC), and is the designation recognized by the United States Air Force as its predecessor for this period.
