War Horror

War horror recognizes what soldiers have always known: that combat is already horror, and that the addition of supernatural or monstrous elements to warfare merely makes visible what is already true — that war reduces human beings to meat, that battlefields are haunted, and that the things people do to each other in wartime are indistinguishable from the worst nightmares fiction can invent.

The subgenre encompasses both supernatural war horror and the horror of war itself rendered through genre conventions. Deathwatch (2002) trapped WWI soldiers in a German trench system that appeared to be alive and malevolent. Overlord (2018) combined D-Day action with Nazi medical experimentation and reanimated soldiers. The Bunker (2001) used claustrophobia and paranoia to make a WWII setting feel like a haunted house. Each of these films uses the war setting to amplify horror's standard elements — isolation, threat, and the breakdown of trust — by placing them in an environment where violence is already the norm.

Films like Come and See (1985) and Threads (1984) demonstrate that war itself, depicted with sufficient unflinching honesty, requires no supernatural element to qualify as horror. The subgenre's most powerful entries understand that the real horror of war is not the monster lurking in the trench but the fact that the trench exists at all.
