Life Before the War Warren attended officer candidate school as a civilian in 1966. He was part of the class 24-66 and completed both Phase I and Phase II of the school’s training at Fort Knox. One of his fellow classmates Sam Dauer characterized Warren as always having a great sense of humor “even in our darkest days.” Below is a series of photos taken at Wozencraft's officer school featuring him and his fellow soldiers training and conversing. The picture at the top of the page was taken in Korea just a few months after Warren’s graduation.
