The second Combat Airlift Competition was held at Travis Air Force Base from 20 – 24 July 1970. This competition was the first to include Reserve associate aircrews. The number of participating wings grew to eight, however, each wing only sent one aircrew in addition to a single aircraft and maintenance team. Additionally, the two MAC numbered air forces, the 21st Air Force and the 22nd Air Force, each dispatched a Combat Control Team and an Aerial Delivery Team to compete. The 1970 competition was the first to include competitive events for the combat controllers including a physical fitness test, marksmanship, and a four-mile (6 km) orienteering course. Also, airdrops were conducted at four different drop zones: Mountain Home Air Force Base, Idaho, Wendover Auxiliary Field, Utah, Naval Air Station Fallon, Nevada, and Camp Roberts, California.
