In the early 1970s the U.S. Army was undergoing seismic changes. The Vietnam War had ended, almost 600 American POWs were released by North Vietnam, the draft was terminated and the Army itself was in dismal shape. A decorated former infantryman turned behavioral scientist, Bob Worthington returned to active duty as a clinician and served as a senior psychology consultant, helping the Army remain an effective fighting force. His insightful memoir describes his pioneering research in PTSD, the managing of a clinical service and mental health center, his work focusing on pilots and aviators, and a stint as a sports psychologist for the U.S. Olympics.
