The President of the United States of America takes pleasure in presenting the Navy Cross to Corporal Miguel A. Rivera-Sotomayor (MCSN: 2174861), United States Marine Corps, for extraordinary heroism while serving as a Grenadier with Company F, Second Battalion, Ninth Marines, THIRD Marine Division (Reinforced), Fleet Marine Force, in Quang Tri Province, Republic of Vietnam, on 29 July 1967. While moving in a battalion-sized operation in connection with Operation KINGFISHER, the entire battalion was attacked by a large element of the North Vietnamese army and began receiving a heavy barrage of mortar, rocket and automatic weapons fire. The Third Platoon of Company F, called to the front of the battle, was pinned down in a heavy cross fire from enemy machine guns. Receiving a call, for his support, Corporal Rivera-Sotomayor responded immediately, though he had been painfully wounded in the arm by shrapnel earlier in the battle. Rushing out into the direct line of enemy fire, with utter disregard for his own safety, he fired his complete supply of ammunition. His firing was so effective that it completely silenced the enemy machine guns and allowed his platoon to move from its pinned down position to establish an effective base of fire against the enemy. With his ammunition expended, Corporal Rivera-Sotomayor observed a machine-gun team whose members were too seriously wounded to fire their gun. Running across the opening in which he was standing, through intensifying enemy automatic rifle fire, he quickly loaded it and again, with no thought of his intense pain or severe wound, stood up with the gun and fired several rounds. Observing that the enemy was shifting positions, he grabbed a rifle and struggling into the open from his covered position, he fired a complete magazine of ammunition. Returning as quickly as possible for another magazine, he had to be restrained by a Corpsman from going out again. By his daring actions and loyal devotion to duty in the face of personal risk, Corporal Rivera-Sotomayor upheld the highest traditions of the Marine Corps and the United States Naval Service.
