Assembly of the Buglers

Damn them stink-ing rot-ten li-ttle BUUU GLEEERS

(soldiers should start throwing shoes, tin cups, and loud epithets towards the bugler)

This is the Wake up Call and is the 'first call' of the day.

Later in the day, If you have a number of buglers in your battalion, it also could be a 'heads up' warning to you that further orders are coming. They don't just "assemble the buglers" for no good reason!
