After graduation, he entered the United States Marine Corps as an officer candidate, training at Parris Island. He was commissioned as a second lieutenant in the Marine Corps in September 1951. As he was preparing to deploy to the war in Korea, his orders were changed, and he spent the rest of his time in the Marine Corps, from 1951 to 1953, teaching communication in the Instructors' Orientation Course. He was discharged in 1953 with the rank of first lieutenant.
