For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as a rifleman with Company M in action against hostile forces. While returning from a reconnaissance-in-force mission in the vicinity of Fire Support Base Cunningham, the 1st Platoon of Company M came under intense automatic weapons fire and a grenade attack from a well concealed enemy force. As the center of the column was pinned down, the leading squad moved to outflank the enemy. Pfc. Wilson, acting as squad leader of the rear squad, skillfully maneuvered his men to form a base of fire and act as a blocking force. In the ensuing fire fight, both his machine gunner and assistant machine gunner were seriously wounded and unable to operate their weapons. Realizing the urgent need to bring the weapon into operation again, Pfc. Wilson, followed by another marine and with complete disregard for his safety, fearlessly dashed across the fire-swept terrain to recover the weapon. As they reached the machinegun, an enemy soldier stepped from behind a tree and threw a grenade toward the 2 marines. Observing the grenade fall between himself and the other marine, Pfc. Wilson, fully realizing the inevitable result of his actions, shouted to his companion and unhesitating threw himself on the grenade, absorbing the full force of the explosion with his own body. His heroic actions inspired his platoon members to maximum effort as they aggressively attacked and defeated the enemy. Pfc. Wilson's indomitable courage, inspiring valor and selfless devotion to duty upheld the highest traditions of the Marine Corps and the U.S. Naval Service. He gallantly gave his life for his country.
