The President of the United States of America takes pride in presenting the Silver Star (Posthumously) to Private First Class Thomas Robert Segar (MCSN: 1158773), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Machine Gun Ammunition Carrier in Company I, Third Battalion, Seventh Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 1 and 2 September 1951. When the enemy launched a vicious counterattack on the company and withering hostile fire from high ground inflicted heavy casualties among his section, Private First Class Segar coolly persisted with his duties as ammunition carrier as the attackers advanced to within forty yards of the machine guns. Seizing an automatic rifle from a fallen comrade, he boldly raised himself to an exposed position to obtain a more effective firing position, personally killed four of the enemy and skillfully directed the machine gun crews in inflicting heavy losses on the hostile force. Despite successive enemy attacks, he bravely maintained his position for over twenty-four hours until he was mortally wounded by hostile fire. By his marked courage, daring initiative and aggressive fighting spirit, Private First Class Segar was greatly instrumental in preventing the enemy from overrunning the position and upheld the highest traditions of the United States Naval Service. He gallantly gave his life for his country.
