Combat soldiers head for their aid station carrying a wounded buddy on a door covered with straw (Battle of the Bulge; December 1944).

Combat wounded

Army engineers carrying mine detectors cautiously probe a snowy road in the Ardennes (Battle of the Bulge). In a dense minefield, engineers often exploded "snakes" - tubes filled with TNT that set off mines for seven feet around.

Looking for mines

Mining a road, a combat engineer lowers a 10-pound antitank charge into a hole and prepares to scoop dirt over it. Sometimes two mines were buried together to increase chances of disabling a heavily armored Tiger tank (Battle of the Bulge, Dec. 1944).
