This is not your typical Vietnam combat veteran memoir. Major Worthington served as an advisor to the Vietnamese military during two tours in Vietnam. This book is focused on his second tour, during which he served first on the Cambodian border and then in the Rung Sat Special Zone. The RSSZ was a tidal estuary athwart the river approaches to Saigon. A well researched book, Worthington provides considerable detail on the role of military advisers. Fluent in Vietnamese, he has a unique perspective on the war in Vietnam. Surviving a near fatal parasitic attack and a gunshot wound, the author left the Army after this tour to attend graduate school. He later rejoined the Army as a psychologist.
