Michael K. Clark, 24
Clark joined the Army after the birth of his son. Money was tight and he had struggled to find regular work. As a soldier, Clark proved fearless, honest, generous and unafraid to speak his mind. When he was killed, Clark's father, a pilot for a contractor that returns soldiers bodies for the military, was part of the crew that brought him home.
