Once the old jokes went...
"Dushman and the Praporcher"
There is an Afghan sniper in the barracks. He looks - the military appears, and in the pursuit of the strip. Looking at the reference book: "Efraytor, the 5 Afghan Prize". Just going to shoot, as he sees, another military, with two strips. Looking at the reference book: "Younger Sergeant, Prize of 10 Afghans". He picked up the rifle and the officer disappeared. He looks - another military appears, with a star on the pursuit. Not long thinking, shoots, looks into the reference book: "Flagger, a fine of 50 Afghans".
