The President of the United States of America takes pleasure in presenting a Gold Star in lieu of a Second Award of the Silver Star to Sergeant Jack Edward Flack (MCSN: 340809), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as Leader of a Light Machine Gun Squad of Company A, First Battalion, Seventh Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 8 March 1951. During the company’s attack against heavily fortified gun emplacements north of Hoengsong, Sergeant Flack repeatedly exposed himself to intense hostile fire to keep pace with the assaulting echelons and to set up his guns in positions calculated to give the assault forces maximum support. When the squad position became untenable after he was critically wounded by a burst of enemy automatic weapons fire, he coolly directed the displacement of the gun to a covered position where it could continue to support the attack before he submitted to treatment for his wounds which proved to be fatal. By his outstanding leadership, courageous fighting spirit and inspiring devotion to duty, Sergeant Flack upheld the highest traditions of the United States Naval Service. He gallantly gave his life for his country.
