LANGLEY AIR FORCE BASE Va. -- Staff Sgts. Marquis Echols (left) and Kevin Hummel, Langley dorm managers, discuss the unit integrity plan for Cunningham Hall. Within the next year, about 30 percent of Airmen living in the dorms will move based on a concept called unit integrity. According to Air Force Instruction 32-6005, unit integrity groups squadron members into dormitories based on the size of the squadron and where they would fit best.
