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.
Pace-Finletter MOU 1952
"...that established a fixed wing weight limit (for the Army) of five thousand pounds empty, but weight restrictions on helicopters were eliminated ..." (Pushing the Envelope, pg. 196)
One of the consequences of President Harry S Truman creating the modern U.S. Defense Department was the splitting off of the U.S. Army Air Forces (the Army Air Corps was disestablished in 1942) from the U.S. Army, and creating the U.S. Air Force. With the Air Force's natural inclination towards Air Superiority and Strategic (i.e., nuclear) priorities, the Army wanted some air capabilities of its own. However, this would mean the duplication of some resources between the Army and Air Force. Eventually there was a meeting between Air Force Secretary Thomas K. Finletter and Army Secretary Frank Pace resulted in the Pace-Finletter MOU of 4 November 1952.
