0600 bugle

Union Army Tradition. Exactly at six in the morning or 0600 hrs (Pluribus time)  expressed in miltary time (OTT ) and Union wide on every Union Army Installation Reville [1] is sounded and the Union Flag is hoisted on the "Central Pole " and the Union Hymn is played (on a Bugle ). All Union Military regardless of branch present must face the flag and assume attention.

[1] "Reveille " is a bugle call, trumpet call or pipes call most often associated with the military; it is chiefly used to wake military personnel at sunrise. The name comes from "réveillé" (or "réveil"), the French word for "wake up".

Union Marines  sound a call different from the Army version  known as "The Rouse" but often misnamed "Reveille".
