This recently declassified 1967 report traces the development of the Assault Airlift capability from its inception through June, 1966. its growth, and the problems associated therewith including equipment, support, facilities and personnel are discussed. Operations during the French/Indo China War are briefly covered in the Introduction as well as "interim" operations following the close of that conflict and up to 1 January 1961. From the latter date, forward, the accomplishments of the 315th Air Division in its assault airlift role are more detailed. To examine the role of assault airlift in Southeast Asia without considering the effects of "out-country", or inter-theater airlift efforts would leave unexplained many of the logistical handicaps under which assault airlift operates today. Hence, the reader will find several references to "out-country" airlift and to organization and control beyond the geographical limits of South Vietnam.
