The UZI is an Israeli compact sub-machine gun that featured one of the first telescoping bolt designs. It fires the 9x19mm Parabellum or .45 ACP round, with a high rate of fire. The Uzi was one of the first weapons to use a telescoping bolt design which allows the magazine to be housed in the pistol grip for a shorter weapon. The first Uzi submachine gun was designed by Major Uziel Gal in the late 1940s. The prototype was finished in 1950. First introduced to IDF special forces in 1954, the weapon was placed into general issue two years later. The Uzi is a popular sub machine gun in the Multiverse, having used by both the Alliance of Nations, the Axis of Empires, and the Coalition of Independent States, along with independent factions such as the Kreisau Circle.
