Err, you know that smoke grenades have been used in ops since ww1? And a smoke machine are often used on APC, there is even a M113 version that can produce enough of it to cover a armored bataillon. Smokes are a must in open ground situation. Well the disco ball thing might be a good idea tough since most pilots have their own mix. They like to play DG while they get to their drop point.
Still, smoke, it's not only a cigarette, it screen you from the ennemy.
