Puller started his service in the Marine Corps fighting guerrillas during the Banana Wars in Central America in the ’20s and ’30s. He went on to serve as a senior officer in World War II and the Korean War. Ultimately awarded five Navy Crosses and one Army Distinguished Service Cross, he was one of only two servicemen with this achievement and is the most decorated Marine in American history. After Korea, Puller took command of the 2nd Marine Division at Camp Lejeune, North Carolina and in 1955 became Deputy Camp Commander. He was retired by the Marine Corps in 1955, with the rank of Lieutenant General. His nickname was related to the way his barrel chest stood out due to his aggressive stance.
