AKS-74u

The AKS-74U is a compact assault rifle, sometimes classified as a sub-machine gun with a folding stock and a shortened barrel that was produced in the Soviet Union from the 1980s to 1991. It was designed to be used by Pilots, Tank Crews and other echelons of the Soviet Army where a full-sized rifle was impractical for defense. In this regard, it is analogous to the German MP5. The AKS-74U fires a 5.45x39MM round, the same as the AK-74 from which it is derived. The AKS-74U is still a frontline weapon in Russia and it is still used by other former Eastern Bloc countries, as well as Soviet-Affiliated states. It is also used by Insurgent groups, although a rarity. The most infamous example of the later is Osama bin Laden, as one is frequently seen with or around the Al-Queda leader in his video addresses. Nicknames for the AKS-74U include Krinkov in English speaking countries and  Ksyusha in Russian-speaking countries.
