Check out the documentary "The Conscientious Objector" 2004.
The Conscientious Objector is a documentary which tells the true story of Desmond T. Doss, a World War II hero who never once touched a firearm. Served on the front lines in Okinawa, never handled a weapon and still won a Congressional Medal of Honor. But he sure had a rough time of it up until then. Quite a story he has.
