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 Force Academy
Support for an air academy got a boost with the National Security Act of 1947, which provided for the establishment of a separate Air Force within the United States military. As an initial measure, Secretary of the Air Force W. Stuart Symington negotiated an agreement where up to 25% of West Point and Annapolis graduates could volunteer to receive their commissions in the newly established Air Force. This was only intended to be a short term fix, however, and disagreements between the services quickly led to the establishment of the Service Academy Board by Secretary of Defense James Forrestal. In January 1950, the Service Academy Board, headed by Dwight D. Eisenhower, then president of Columbia University, concluded that the needs of the Air Force could not be met by the two existing U.S. service academies and that an air force academy should be established.
