The President of the United States of America takes pleasure in presenting the Silver Star to Sergeant Edmund N. Marx, Jr. (MCSN: 1129212), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Tank Commander of Company C, First Tank Battalion, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea from 24 to 27 July 1953. With his vehicle surrounded and physically assaulted by hostile troops during a vicious enemy attack on a friendly outpost position, Sergeant Marx called down fire upon his own position in an attempt to halt the savage attack. On another occasion, when an enemy attack was impending, he volunteered to act as a gunner on another vehicle in an attempt to aid two disabled tanks located on the same strategic position. Upon arriving at the area, he unhesitatingly dismounted from his tank under a murderous hail of hostile mortar and artillery fire in order to attach towing cables to the disabled vehicles. After ground-guiding the tanks to a position of safety, he remounted his vehicle and proceeded to deliver devastating fire upon the attackers. When the assaulting enemy attempted to climb on his vehicle, he opened the hatch and fearlessly exposed himself to enemy fire to accurately hurl hand grenades and disperse the hostile troops. By his indomitable fighting spirit, courageous initiative and unyielding devotion to duty, Sergeant Marx served to inspire all who observed him and upheld the highest traditions of the United States Naval Service.
