Buglers start the beginning of the day for the military with the Assembly of Trumpeters, which is similar to "La Garde a Vous." This is followed by Reveille, Assembly, Mess Call, Sick Call, Drill Call, Assembly, First Sergeant's Call, Officer's Call, Recall, Mail Call, Mess Call (noon), Drill Call, Assembly, Recall, First Call, Assembly, Retreat, To the Color, Mess Call (evening), Tattoo, Call to Quarters and Taps (optional). Guard Mounting is called only when scheduled and Adjutant's Call is called only for parades, according to the U.S. Army Bands website.
Soldiers appointed to work party respond to the Fatigue Call. First Call and Drill Call are for soldiers assigned to morning drill and for those practicing the Manual of Arms, bayonet drills and marching. Recall from Drill and Recall from Fatigue signaled soldiers to stop drill and work. First Sergeant's Call signal company first sergeants to report to post headquarters with morning reports. Assembly Call marks the time for the garrison to turn out for the Retreat Ceremony.
Retreat Call is played for the flag-lowering ceremony at the end of the day. Tattoo tells the soldiers to prepare for bed; the post is also secured at this time. The Assembly Call signals bed check (last roll call of the day). Taps tells the soldiers to turn out all lights, get in bed and cease all talking.
