Hitler survived the war as a combat soldier—a rifle carrier—in a frontline infantry regiment. The achievement was an extraordinary one based on some combination of near-miraculous luck and combat skill. The interpretive fussing over whether or not Hitler was a combat soldier because he spent most of the war in the part of the regiment described as regimental headquarters can be laid to rest as follows: Any soldier in an infantry regiment on an active front in the west in World War I must be considered to have been a combat soldier.
