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.
Idaho Air National Guard
18 September 1947, however, is considered the Idaho Air National Guard's official birth concurrent with the establishment of the United States Air Force as a separate branch of the United States military under the National Security Act. The initial mission of the Idaho ANG was the air defense of the state. On 1 July 1955 the 190th Fighter-Interceptor Squadron was authorized to expand to a group level, and the 124th Fighter Group (Air Defense) was allotted by the National Guard Bureau, extended federal recognition and activated.
