David Herbert McNerney (June 2, 1931 – October 10, 2010) was a United States Army soldier and a recipient of the United States military's highest decoration—the Medal of Honor—for his actions in the Vietnam War. He earned the Medal of Honor as a first sergeant on March 22, 1967, for taking command of his company during an attack by a numerically superior North Vietnamese force. Although wounded, he organized the unit's defense, exposed himself to hostile fire in order to mark and clear a helicopter landing site, and refused to be evacuated until a new commander arrived the next day. McNerney retired from the military in 1969, after serving four tours of duty in Vietnam.
