The President of the United States of America takes pleasure in presenting the Navy Cross to Sergeant Robert T. Roller (MCSN: 1998691), United States Marine Corps, for extraordinary heroism as a Squad Leader with Company F, Second Battalion, Fifth Marines, FIRST Marine Division (Reinforced), Fleet Marine Force, in the Republic of Vietnam on 13 October 1966. During a search and clear operation near the Demilitarized Zone in Quang Tri Province, the lead elements of the company were attacked by enemy sniper fire. Sergeant Roller’s platoon was deployed to pursue and eliminate the snipers. They were hit by extremely heavy automatic weapons fire and grenades from a large enemy force concealed in a well camouflaged trench line. Although painfully wounded in the hand and leg from the initial burst of fire, he quickly gave first aid to the other wounded Marines and organized the evacuation of his fallen comrades, at the same time directing a heavy volume of fire on the enemy position. He also assisted in bringing in medical evacuation helicopters for the more critically wounded. Disregarding his wounds, he refused evacuation and rejoined his platoon to rally the men and charge the heavily fortified enemy position. With only a pistol, Sergeant Roller led the assault, shouting encouragement to his men, and was wounded again. His aggressive and heroic actions in the face of grave personal danger inspired his men to overrun the enemy, routing them from their position and causing them to leave seven of their dead and numerous weapons behind. By his daring initiative, inspiring leadership and indomitable fighting spirit, Sergeant Roller upheld the highest traditions of the Marine Corps and the United States Naval Service.
