AKS-74U

AKS-74U, or Avtomat Kalashnikova 74 Ukorochennyj (romanized from АКС-74У and Автомат Калашникова Укороченный), Ukorochennyj meaning shortened, is a Russian assault rifle chambered in 5.45x39mm. It was developed to be used by personnel in confined spaces, such as vehicle crews and combat chefs, and SPECNAZ troops. The airborne and special forces troops quickly came to the conclusion that the short weapon performs poorly in combat, especially over longer ranges, and it was not picked up for use in those circles. Today it is mainly used by vehicle crews and police.
