I don't get ticked - the Staff Sergeant voice comes on and very quietly says "Get up off your ass." Amazing how you can project that voice, and still be quiet.
TB,
I was at the Tomb of the Unknowns a coupla years ago and waited for the changing of the guard.
The Sergeant of the Guard, an E6 or E7, explained to the 50-odd people in the crowd what the ceremony was for, how it worked, etc, and that people were supposed to stand up for it.
When the moment came, and people were kind of moving slowly and half-assed if at all, he threw some command inflection into a bellowed, "on your feet!"
You never saw so many overfed, pasty tourists move that fast in your life!
