As a former squaddie who served in the 1970s, I wonder if you guys still get 'smoke breaks' these days? During my time practically everybody smoked cigarettes and smoke breaks were a recognised perk, especially during drill. I'm sure they still continue but what do politically correct drill pigs call them? These days smokers are a low percentage of the population so I assume that low figure translates into the present day army. (Mind you in my day we had hardy anybody booted out of the army for drug offences). And I bet there is an expression popular today as it was in my day when the NCOs want everybody to rush: "You're are only wasting your own time!"
