This is the second volume in a series of chronological histories prepared by the Marine Corps History and Museums Division to cover the entire span of Marine Corps involvement in the Vietnam War. This volume details the Marine activities during 1965, the year the war escalated and major American combat units were committed to the conflict. The narrative traces the landing of the nearly 5,000-man 9th Marine Expeditionary Brigade and its transformation into the ΙII Marine Amphibious Force, which by the end of the year contained over 38,000 Marines. During this period, the Marines established three enclaves in South Vietnam’s northernmost corps area, I Corps, and their mission expanded from defense of the Da Nang Airbase to a balanced strategy involving base defense, offensive operations, and pacification. This volume continues to treat the activities of Marine advisors to the South Vietnamese armed forces but in less detail than its predecessor volume, U.S. Marines in Vietnam, 1954-1964; The Advisory and Combat Assistance Era.

Contents: The Prewar Experience; Evolution of Airborne Forces During World War II; Operational Employment: Vyaz'ma, January-February 1942; Operational Employment: Vyaz'ma, February-June 1942; Operational Employment: On the Dnepr, September 1943; Tactical Employment; The Postwar Years.

This collection of squadron histories has been prepared by the USAF Historical Division to complement the Division's book, Air Force Combat Units of World War II. The 1,226 units covered by this volume are the combat (tactical) squadrons that were active between 7 December 1941 and 2 September 1945. Each squadron is traced from its beginning through 5 March 1963, the fiftieth anniversary of the organization of the 1st Aero (later Bombardment) Squadron, the first Army unit to be equipped with aircraft for tactical operations. For each squadron there is a statement of the official lineage and data on the unit's assignments, stations, aircraft and missiles, operations, service streamers, campaign participation, decorations, and emblem.

This work provides an organizational history of the maneuver brigade and case studies of its employment throughout the various wars. Apart from the text, the appendices at the end of the work provide a ready reference to all brigade organizations used in the Army since 1917 and the history of the brigade colors.
