The Army runs, you don't see many smokers run. If they do it's not a pretty sight with that green and yellow crap that comes out of there noses and mouths. The smoking fools will drop out before the 5th mile in just a PT uniform, imagine what they will do with 85lbs of equipment on them and running through the Iraqi desert.
Luckily the Army has drill sergeants that will slap a new attitude on smokers and make them men.
