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.
Uniforms of the United States Air Force
When the U.S. Air Force first became a fully separate branch in 1947 personnel continued to wear uniforms nearly identical to the U.S. Army. The first Air Force-specific blue dress uniform, introduced in 1949, was in Shade 1683, also dubbed "Uxbridge Blue" after the former Bachman-Uxbridge Worsted Company. An Ike jacket, inherited from the Army Air Forces but in Shade 1683, was an optional uniform item.
