Marine Advisors with the Vietnamese Provincial Reconnaissance Units, 1966-1970
...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....
