This study is the fourth in a series prepared by the Office of Air Force History concerning logistics support of the air war in Southeast Asia. As in the case of the preceding works, its purpose is not to describe Air Force logistic support as such. Rather, it is to point up some of the problems dealt with and plans formulated by the air logistic staff in the period January 1968 through December 1969. The series also includes the following titles: USAF Logistic Plans and Policies in Southeast Asia, 1965; USAF Logistic Plans and Policies in Southeast Asia, 1966; and USAF Plans and Policies: Logistic and Base Construction in Southeast Asia, 1967. In addition, the Office of Air Force History has issued nine other studies dealing with various aspects of Air Force participation in Southeast Asia. Among the latter titles are: The Air Force in Vietnam: The Search for Military Alternatives, 1967; USAF Plans and Policies: R&D for Southeast Asia, 1968; and The Air Force in Southeast Asia: The Administration Emphasizes Air Power, 1969.
