SMG

A submachine gun (SMG) is an automatic carbine, designed to fire pistol cartridges. It combines the automatic fire of a machine gun with the cartridge of a pistol. An assault rifle, in contrast, uses an intermediate-power cartridge with more power than a pistol but less than a standard rifle or battle rifle.

UZI


The Uzi (Hebrew: עוזי‎, officially cased as UZI) is a related family of open bolt, blowback-operated submachine guns. Smaller variants are considered to be machine pistols. The Uzi was one of the first weapons to use a telescoping bolt design which allows for 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 has found use as a personal defense weapon by rear-echelon troops, officers, artillery troops and tankers, as well as a frontline weapon by elite light infantry assault forces.
Over its service lifetime, the Uzi was manufactured by Israel Military Industries, FN Herstal, and other manufacturers. From the 1960s through the 1980s, Uzi submachineguns were sold to more military and police markets than any other submachinegun ever made.
