The term SUBMARINE GUN can be summarized as an UZI, which is a three-letter acronym for a type of submachine gun. The Uzi was designed by Major Uziel Gal in the late 1940s and was first used by the Israeli military in the 1950s. It has since become one of the most popular submachine guns in the world, with variants being used by militaries, law enforcement, and civilians. The Uzi is known for its compact size, high rate of fire, and low recoil.
