On 10 November 1947, the 81st Infantry Division was reconstituted in the Organized Reserve Corps (known as the United States Army Reserve after 1952) with the division headquarters at Atlanta, Georgia. Under War Department guidelines, the 81st was organized as a Class C reserve unit with 60% of the authorized officer cadre, but no authorized enlisted members. In the event of a wartime mobilization, the division would expand to wartime strength with called up reservists and new inductees. However, during the 1950s and 60s, the 81st Infantry Division was not called up for service during the Korean War or Berlin Crisis. As part of the 1962 reorganization of the Reserve Components initiated by Secretary of Defense Robert McNamara, the 81st Infantry Division was selected for inactivation, which was completed on 31 December 1965.
