The President of the United States of America takes pleasure in presenting the Silver Star to Sergeant Stephan L. Constantine (MCSN: 1151296), United States Marine Corps, for conspicuous gallantry and intrepidity while serving with Company I, Third Battalion, Fifth Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 6 and 7 September 1952. When a friendly outpost was brought under heavy enemy artillery, mortar and small arms fire followed by an attack by a numerically superior enemy force, Sergeant Constantine courageously exposed himself to the hostile fire by positioning himself on top of one of the few remaining bunkers to deliver more effective fire upon the enemy and, although knocked unconscious by concussion during the first assault, remained at his position. Buried alive under an avalanche of rubble during the second assault, he dug himself out and continued to deliver accurate and effective fire throughout the attacks, passing vital ammunition and grenades to other Marines who were away from the main supply. By his outstanding courage, daring initiative and aggressive fighting spirit, Sergeant Constantine served to inspire all who observed him and upheld the highest traditions of the United States Naval Service.
