The AH-64 Apache is a United States Army attack helicopter that entered service in the 1980s, armed with a single 30mm M230 chain gun under its chin turret. Clips of its distinctive firing burst have circulated for years through military footage, flight simulators and shooters like Arma and DCS World. Editors reuse the recording because few other helicopter weapons sound this heavy and rhythmic, so it has become a go-to shorthand for Apache attacks in documentaries, edits and meme videos.
