Artillery fire support bases of the Freeworld forces played a critical role in the conduct of operations during the Vietnam War. They served to lay down high-volume fire on enemy firing sites, supported friendly infantry operations, and executed harassing fire missions where exact targets were not known. But the firebases themselves which housed a range of other facilities such as troop shelters, surveillance radars and command centers had to be defended against ground attack, and as a result became significant fortifications in their own right. This book describes the design, development and operational history of the fire support bases throughout the conflict.

An account of the costly 1971 surprise attack on Firebase Mary Ann draws on declassified documents and interviews with more than fifty veterans of the 1st Battalion of the 46th Infantry. Reprint.

The stories of war and survival told by the Marines that were there "What shines through from this bare-knuckled, furious battle is the core ethos. It comes though loud and clear when you read chapter after chapter in different voices. These Marines had no battlefield prep, no intelligence, no cohesive leadership. What held them together was the Marine spirit. There was nothing else. Wow! What an epic fight!" - Bing West, author of The Last Platoon and The Village "LZ Sitting Duck shows battle from the bottom up. In personal statements it captures the chaos, bravery, confusion, fear, and fighting spirit of Marines of the First Battalion Fourth Marines who fought a fierce hill battle with regular North Vietnamese Army forces in March of 1969. Readers will learn about combat down in the dirt at the very tip of the spearpoint." - Karl Marlantes, author of Matterhorn and What's It Like To Go To War

This work describes riverine combat during the Vietnam War, emphasizing the operations of the U.S. Navy’s River Patrol Force, which conducted Operation Game Warden; the U.S. Army-Navy Mobile Riverine Force, the formation that General William Westmoreland said “saved the Mekong Delta” during the Tet Offensive of 1968; and the Vietnam Navy. An important section details the SEALORDS combined campaign, a determined effort by U.S. Navy, South Vietnamese Navy, and allied ground forces to cut enemy supply lines from Cambodia and disrupt operations at base areas deep in the delta. The author also covers details on the combat vessels, helicopters, weapons, and equipment employed in the Mekong Delta as well as the Vietnamese combatants (on both sides) and American troops who fought to secure Vietnam’s waterways. Special features focus on the ubiquitous river patrol boats (PBRs) and the Swift boats (PCFs), river warfare training, Vice Admiral Elmo R. Zumwalt Jr., the Black Ponies aircraft squadron, and Navy SEALs. This publication may be of interest to history scholars, veterans, students in advanced placement history classes, and military enthusiasts given the continuing impact of riverine warfare on U.S. naval and military operations in the 21st century.

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.
