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.
Nineteenth Air Force
The Nineteenth Air Force was inactivated in July 1973, as part of the economies enacted after the end of the Vietnam War. On 4 August 1998, the Chief of Staff of the United States Air Force (CSAF), General Michael E. Ryan, and the Acting Secretary of the Air Force (SECAF), F. Whitten Peters, announced their plans to implement a major change in the structure of the Air Force. They proposed to divide the USAF’s combat strength and the elements directly supporting it into ten Aerospace Expeditionary Forces (AEFs). Although the EAF concept was a major step in recasting the operations, outlook, and culture of the USAF, it sprang from the performance of missions traditionally performed by the Air Force — the timely response of land-based air power to the needs of the nation.
