Ten years after the end of the American involvement in the Vietnam War, a career Foreign Service officer, Thomas J. Corcoran, set down in writing his thoughts on the history of U.S. State Department policy during America's involvement with South Vietnam. Like many Americans of his generation, he was perplexed by the failure of America to achieve its goals in South Vietnam. As an ambassador and with over 30 years of diplomatic experience – beginning in 1948 when he was assigned to Hanoi and involving other postings in Southeast Asia – he brought to his analysis a long and rich personal experience with events in Laos, Cambodia, and Vietnam. The result is a thoughtful, objective and well-researched study that chronicles the key policy decisions made by the US State Department throughout the entire period from 1945 to 1975; decisions that ultimately led to the first war lost by the United States. In his extensive study, Corcoran does an excellent job of exposing many of the myths and falsehoods found in orthodox histories of U.S. involvement in Vietnam.

This book recounts the experiences of a young US Marine officer during the Vietnam War as he fights that war over a nineteen month period in three different geographical areas of South Vietnam. He graphically explains to the reader what it was like to perform three distinct combat missions: long-range ground reconnaissance in the Annamite Mountains of I Corps, infantry operations in the rice paddies and mountains of Quang Nam Province, and special police operations for the CIA in Tay Ninh Province. The author describes in rich detail each of these distinct military activities and provides powerful and explicit examples of each. Using primary sources, such has US Marine Corps official unit histories, CIA documents, and his weekly letters home to his parents, the author relies almost exclusively on primary sources to convey to the reader a story that is devoid of hyperbole and focused on providing an accurate and honest account of combat at the small unit level. Of particular interest to students of the war is his description of his assignment to the CIA as a Provincial Reconnaissance Unit (PRU) advisor in Tay Ninh Province, where he participated in several secret missions as part of the controversial Phoenix Program. He also reveals the name and contribution of the CIA's most valuable spy during the war, the famous "Tay Ninh Source".

The leader of one of the most successful U. S. Marine long range reconnaissance teams during the Vietnam War, Andrew Finlayson recounts his team's experiences in the pivotal period in the war, the year leading up to the Tet Offensive of 1968. Using primary sources, such as Marine Corps unit histories and his own weekly letters home, he presents a highly personal account of the dangerous missions conducted by this team of young Marines as they searched for North Vietnamese Army and Viet Cong units in such dangerous locales as Elephant Valley, the Enchanted Forest, Charlie Ridge, Happy Valley and the Que Son Mountains. Taking only six to eight men on each patrol, Killer Kane searches for the enemy far from friendly lines, often finding itself engaged in desperate fire fights with enemy forces that vastly outnumber this small band of brave Marines. In numerous close contacts with the enemy, Killer Kane fights for its survival against desperate odds, narrowly escaping death time and again. The book gives vivid descriptions of the life of recon Marines when they are not on patrol, the beauty of the landscape they traverse, and several of the author's Vietnamese friends. It also explains in detail the preparations for, and the conduct of, a successful long range reconnaissance patrol.

While most Marines think of the Vietnamese Marine Corps as the primary advisory experience during that conflict, Marines served with other programs. One of these is the subject of this study: Marine advisors with the Vietnamese Provincial Reconnaissance Units (PRUs). This narrative is a combination of experience, research, and reflection.While other journalistic or academic accounts have been published, this is a narrative of participants. Many historians consider the two most effective counterinsurgency organizations employed during the VietnamWar to have been the PRU and USMC Combined Action Platoons (CAP). The author believes that both of these programs have applicability in any counterinsurgency where U.S. forces are called upon to assist a host government.

U.S. Marines as advisors have a long history, from Presley O'Bannon atTripoli through Iraq and Afghanistan via Haiti, Dominican Republic, Nicaragua, China, South Korea, Taiwan, Philippines, and Vietnam. While most Marines think of the Vietnamese Marine Corps as the primary advisory experience during that conflict, others served with various other advisory programs with the U.S. Army, U.S. Navy, U.S. Joint Special Operations, and U.S. Civil Operations and Rural Development Support. One of these is the subject of this study: Marine advisors with the Vietnamese Provincial Reconnaissance Units (PRUs). This narrative is a combination of experience, research, and reflection. While other journalistic or academic accounts have been published, this is a narrative of participants. Many historians consider the two most effective counterinsurgency organizations employed during the Vietnam War to have been the PRU and USMC Combined Action Platoons (CAP). In both cases, U.S. Marines played a significant role in the success of these innovative programs. It should be pointed out, however, that the number of U.S. Marines assigned to these programs was small and the bulk of the forces were locally recruited fighters. Both programs used a small cadre of Marines providing leadership, training, and combat support for large numbers of indigenous troops, and in so doing, capitalized on the inherent strengths of each. The author believes that both of these programs have applicability in any counterinsurgency where U.S. forces are called upon to assist a host government. Obviously, adjustments to these programs would have to be made to take into account local conditions, but the core concept of providing U.S. Marines to command or advise local militia and special police units is one that has great promise for success. With a clear understanding of why the PRUs and CAPs worked, and with the necessary adjustments to take into account local conditions, similar units can be created to defeat future insurgencies. With this in mind, the author hopes that this work will provide U.S. military planners with insights into creating and managing units capable of defeating a well-organized and highly motivated insurgent political infrastructure
