Hacksaw Ridge [2016 film]

During the bloodiest battle of WWII, in Okinawa, Desmond Doss saved 75 men without firing or carrying a gun. He was the only American soldier in WWII to fight on the front lines without a weapon, as he believed that while the war was justified, killing was nevertheless wrong. As an army medic, he singlehandedly evacuated the wounded from behind enemy lines, braved fire while tending to soldiers and was wounded by a grenade and hit by snipers. Doss was the first conscientious objector to ever earn the Congressional Medal of Honor.
