The President of the United States of America takes pleasure in presenting the Silver Star to Sergeant Anthony J. DeMasi (MCSN: 1036973), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as Squad Leader of Company A, First Battalion, First Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 10 June 1951. Assigned the mission of assaulting a strongly defended enemy hill position, Sergeant DeMasi skillfully maneuvered his men in a flanking attack. When the unit was subjected to withering hostile automatic-weapons fire from a concealed bunker, he single-handedly charged forward to assault the emplacement and succeeded in silencing the enemy weapon, thereby permitting his squad to continue the advance. Later, when the platoon sergeant became a casualty, he quickly assumed command and courageously led the foremost squad in the successful seizure of the enemy position. By his skilled leadership, aggressive fighting spirit and unwavering devotion to duty, Sergeant DeMasi contributed materially to the success achieved by the company and upheld the highest traditions of the United States Naval Service.
