The provided source material does not contain information regarding a city named Uzi in Tanzania. Instead, it describes the Uzi as a family of Israeli open-bolt, blowback-operated submachine guns and machine pistols. First designed by Major Uziel "Uzi" Gal in the late 1940s following the establishment of the State of Israel, these firearms were among the first to incorporate a telescoping bolt design. This specific engineering feature allows the magazine to be housed within the pistol grip, resulting in a shorter weapon profile.
