Place and date: Chau Doc Province, Republic of Vietnam, 5 April 1970. Entered service at: Bangor, Maine. Born: 3 November 1949, Benton, Maine. Citation: For conspicuous gallantry and intrepidity in action at the risk of life above and beyond the call of duty. Sgt. Buker, Detachment B-55, distinguished himself while serving as a platoon adviser of a Vietnamese mobile strike force company during an offensive mission. Sgt. Buker personally led the platoon, cleared a strategically located well-guarded pass, and established the first foothold at the top of what had been an impenetrable mountain fortress. When the platoon came under the intense fire from a determined enemy located in 2 heavily fortified bunkers, and realizing that withdrawal would result in heavy casualties, Sgt. Buker unhesitatingly, and with complete disregard for his personal safety, charged through the hail of enemy fire and destroyed the first bunker with hand grenades. While reorganizing his men for the attack on the second bunker, Sgt. Buker was seriously wounded. Despite his wounds and the deadly enemy fire, he crawled forward and destroyed the second bunker. Sgt. Buker refused medical attention and was reorganizing his men to continue the attack when he was mortally wounded. As a direct result of his heroic actions, many casualties were averted, and the assault of the enemy position was successful. Sgt. Buker’s extraordinary heroism at the cost of his life are in the highest traditions of the military service and reflect great credit on him, his unit, and the U.S. Army.
