I was a ROTC commissioned officer (1966), went to Ft Benning for Infantry School in 1968 after two years Reserve (when I was getting a M.S. in Geology). Almost all of my buddies went right to Nam after that, but I was sent to Ft Holabird to the Intelligence School (now at Ft Huachuca). Most of the I.S. grads went right to Nam, and I volunteered to go, but was selected for the D.I.A. and sent to the Pentagon, where I served for three years, reaching rank of Captain. I was an aerial surveillance officer and looked at every square inch of N&S Viet Nam, Laos, Cambodia and other areas (including the Middle East). If you remember the Son Tay prison camp raid in N. Viet Nam--I was the main photo interpreter for that...also for the Cambodian Invasion (it was my annotated pictures Nixon was holding in the TV press conference announcing the invasion)....went back to college in 1972.
