Made in 1966, two years after the Gulf of Tonkin Incident, this U.S. Navy film report shows the activities of the 7th Fleet and its activities in Southeast Asia and Vietnam. It includes aircraft carrier operations, naval gunfire support and attack, riverine operations and more. Also shown is Operation Jackstay. JACKSTAY was an amphibious operation, launched from the USS Princeton, that utilized surface borne and helicopter borne assault forces. D-day for this search and destroy mission: 26 March 1966 . The scheme of maneuver dictated two phases over a period of about ten days. Phase One: a provisional rifle company lands over Red Beach and establishes blocking positions, and lands an artillery battery over Red Beach as well. At the same time, the Marines of Charlie Company heli-lifted into LZ Sparrow and established blocking positions; Alpha Company lands in LZ Rob in to secure the LZ and provide a defensive perimeter for subsequent landings, and Bravo, Delta and H & S Companies and other combat support and service support elements follow Alpha Company into LZ Rob in. The initial phase of the operation focused on securing three objectives within approximately two days. Phase Two operations would largely depend on the situation as it developed, the availability of helicopters and surface craft, and the time and space factors dictated by the terrain and weather.
