If you think post-traumatic stress disorder is a new phenomenon, check out this fascinating video made right here at Camp Pendleton in 1954, the Korean War era, with Leonard Nimoy (long before Star Trek fame) and Fess Parker of Davy Crockett. Produced by the Marine Corps, this film looks at the role of the Division Psychiatrist in dealing with Marines with varying degrees of what they then called combat fatigue, or shell shock. Leonard Nimoy and Fess Parker play shell-shocked Marines.
