After the demobilization of the Army of the United States in 1946, the United States Army was divided into the Regular Army (RA) and the Army Reserve (USAR). During the Korean War, the Army of the United States was reinstated but had only enlisted draftees. Officers after this point held Regular Army rank only, but could hold an additional "temporary" rank in addition to their permanent rank. Temporary Regular Army ranks were not as easily revoked as the former AUS ranks.
