Ralph H. Johnson

Ralph Henry Johnson (January 11, 1949 – March 5, 1968) was a United States Marine who posthumously received the Medal of Honor for heroism in March 1968 during the Vietnam War. When a hand grenade was thrown into his fighting hole, he immediately covered it with his body—absorbing the full impact of the blast—sacrificing his life to save a fellow Marine and preventing the enemy from penetrating his patrol perimeter.
