See applied for military officer training and received an appointment to the United States Merchant Marine Academy (USMMA) in 1945. As the end of the war drew near, the USMMA changed its curriculum to a four-year college-level program, which was the minimum requirement to be a merchant marine in peacetime. He spent his plebe year at Pass Christian, Mississippi, where the USMMA had a satellite campus, and then transferred to the main campus at Kings Point, New York. He commanded the Third Company as a cadet officer. He was a member of the Propeller Club and head cheerleader. He was on the mile relay running team, played intramural softball, and was a varsity boxer. As co-captain of the rifle team, he won the Captain Tomb Trophy for individual rifle and pistol marksmanship in December 1948. In 1949, Congress authorized the USMMA to award Bachelor of Science degrees to its graduates, so on graduation that year Elliott received his degree, his marine engineer’s licenses, and a commission as an officer in the United States Navy Reserve.
