The line comes from Dawn of War, the Warhammer 40,000 real-time strategy game where Imperial Guard units call out battlefield threats as they fight. Like other enemy spotted warnings in the series, it was clipped by players and shared on soundboards for use in gameplay videos, streams and memes. Its appeal has lasted because the delivery is instantly recognisable to Warhammer fans yet clear enough for anyone to understand, turning a routine in-game alert into a ready-made warning for any sudden danger on screen.
