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.
List of United States Air Force squadrons
This is a list of United States Air Force squadrons. It covers both the independent United States Air Force (USAF) and its period as a branch of the US Army culminating as the Army Air Forces up to 1947. All numbered USAF squadrons are assigned numbers from 1 to 999, with the block 101 to 300 being reserved for the Air National Guard. Generally speaking the numbers in the 900 block are post World War II units, they may however be consolidated units with lineage and heraldry dating back to World War II or even early as part of the Air Service. The only official source of lineage information is provided by the Air Force Historical Research Agency at Maxwell Air Force Base, Alabama. The only official sources of heraldry information are the AFHRA and the Institute of Heraldry, Fort Belvoir, Virginia.
