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.
Religious symbolism in the United States military
On July 28, 1942, Chaplain Charles Carpenter was appointed to the newly created position of air chaplain for the Army Air Force, within the larger United States Army organization. Later, when the United States Air Force was established as a separate service on September 18, 1947, the original plan was that chaplain support would continue to be provided by Army chaplains. However, on May 10, 1949, the decision was made that the still new branch of the military would have its own chaplains. At that point, chaplains serving with the Air Force began to wear Air Force uniforms, but continued to use the same Jewish and Christian Chaplain Corps insignia that had been used by the Army. In 1981, when the Navy approved the change to the Jewish chaplain insignia, from Roman numerals to Hebrew letters, both the Army and Air Force made the same change soon thereafter. Since then, the approval of insignia to represent chaplains of other faith groups has been made jointly by of all branches of the United States Armed Forces. However, while the designs for the insignia are the same for all services, the Air Force categorizes the insignia as "occupational badges," with different "wear use" rules than the other services.
