Carl Raguse was a career military officer, who trained at the US Military Academy at West Point, graduating in 1924. He competed at the 1936 Olympics as a captain in the US Army, riding in both jumping and eventing. Shortly before the Berlin Olympics Raguse placed third with the US team at the Prix de Nations event in Lucerne, Switzerland. Raguse eventually achieved the rank of colonel. After graduation from West Point he was assigned to Fort Myers, Virginia, where he was a member of the Rough Riders who regularly gave cavalry exhibitions, and then his later assignments included Fort Ringgold, Texas (1928-29) and then Fort Riley, Kansas (1930-31), where he served in the Troops Officers Course. He was also second-in-command at Fort Reno Horse Cavalry prior to that post being decommissioned.
