The march comes from Police Academy, the 1984 American comedy about a group of unlikely recruits admitted to a city police academy. Composer Robert Folk wrote the film's score, and its main march became the series' most recognisable musical cue across sequels and parodies. Online, the clip survives detached from the movie as shorthand for pompous, by-the-book authority, shared in edits where an entrance, inspection or group walk needs instant mock-official weight.
