Assembly is a traditional United States Army bugle call used to signal soldiers to gather at a designated place, part of the daily routine of calls that structured camp life long before radio. This recording circulated as a Hollywood Edge library fanfare and is associated with the Donald Duck wartime cartoon Fall Out Fall In, released April 23, 1943, where Donald experiences army routines. Online, the short call survived as a reusable cue for roll calls, reveille jokes, and any moment needing instant military order.
