For the next decade, TAC would be consumed by operations in Vietnam, Cambodia and Laos. On a daily basis, flight crews trained by TAC would hurl themselves and their planes at targets across the area of operations, to include over the skies of North Vietnam. As the command responsible for training aircrews for overseas duty, TAC maintained Readiness Training Units in the United States to train pilots and other aircrew members for fighters, reconnaissance and troop carrier (redesignated tactical airlift after 1 July 1966) squadrons in the Pacific.
