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.
Site selection
The United States Air Force was created in 1947 as an independent service branch and legislation was passed to create a United States Air Force Academy. Selecting the best location for the academy was deemed critical by Congress and the Air Force Academy Site Selection Board was established to manage the task. The board evaluated more than 580 locations in 22 states before selecting the current Colorado Springs site.
