One Four Man Up is my personal memoirs of my experiences as a Marine Tactical Air Controlman during the Vietnam war. The books covers why I joined the Marine Corps in 1966, the training I went through, and my combat experiences in a Marine line company from April 1968 to May 1969. The book then explains how I was treated when I returned home, the PTSD I endured for over 20 years, and how I overcame it.
