I've never smoked; nasty habit.
But I remember the drill:
All together:
"SIR, The smoking formation for platoon wun thousand and five is lit, for one cigarette, and one cigarette only SIR!"
Then the formation leader would say: "Light 'em up, privates!"
The group: "Aye, aye, private!"
After a few minutes the formation leader would bellow: "Take your last drag, privates!"
"Aye, aye, private!"
And they'd police up the butts and come back inside.
