1959, the Air Force Reserve flying force consisted of 45 troop carrier squadrons assigned to 15 troop carrier wings. The squadrons were not all located with their parent wings, but were spread over thirty-five Air Force, Navy and civilian airfields under what was called the Detached Squadron Concept. The concept offered several advantages. Communities were more likely to accept the smaller squadrons than the large wings and the location of separate squadrons in smaller population centers would facilitate recruiting and manning. However, under this concept, all support organizations were located with the wing headquarters. Although this was not a problem when the entire wing was called to active service, mobilizing a single flying squadron and elements to support it proved difficult. This weakness was demonstrated in the partial mobilization of Air Force Reserve units during the Berlin Crisis of 1961. To resolve this, at the start of 1962, Continental Air Command, (ConAC) determined to reorganize its Air Force Reserve wings by establishing groups with support elements for each of its troop carrier squadrons. This reorganization would facilitate mobilization of elements of wings in various combinations when needed. Activation of the 927th Troop Carrier Group As a result of these organizational changes, the 927th Troop Carrier Group (927 TCG) was established at what was then Selfridge Air Force Base, Michigan on 11 February 1963 as the headquarters for the 63d Troop Carrier Squadron (63 TCS), with the 63 TCS having been stationed at Selfridge AFB since November 1957. Along with group headquarters, a Combat Support Squadron, a Materiel Squadron, and a Tactical Infirmary were organized to support the 63 TCS. If mobilized to active duty, the 927 TCG was operationally gained by Tactical Air Command (TAC), which was also responsible for its training. The 927 TCG's mission was to organize, recruit and train Air Force Reservists in the tactical airlift of airborne forces, their equipment and supplies and delivery of these forces and materials by airdrop, landing or cargo extraction systems. The 927 TCG was one of three Fairchild C-119 Flying Boxcar troop carrier groups assigned to the 403d Troop Carrier Wing (403 TCW) at Selfridge AFB in 1963. The other groups were geographically separated units (GSUs) consisting of the 928th Troop Carrier Group (928 TCG) at O'Hare Air Reserve Station at O'Hare International Airport, Illinois and the 929th Troop Carrier Group (29 TCG) at Davis Field, Oklahoma.
