Operational use

The Uzi gun was designed by Major (Captain at the time) Uziel Gal of the Israel Defense Forces (IDF) following the 1948 Arab-Israeli War. The weapon was submitted to the Israeli army for evaluation and won out over more conventional designs due to its simplicity and economy of manufacture. Gal did not want the weapon to be named after him, but his request was ignored. The Uzi was officially adopted in 1951. First introduced to IDF special forces in 1954, the weapon was placed into general issue two years later. The first Uzis were equipped with a short, fixed wooden buttstock, and this is the version that initially saw combat during the 1956 Suez campaign.[2] Later models would be equipped with a folding metal stock.

The Uzi was used 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. The Uzi's compact size and firepower proved instrumental in clearing Syrian bunkers and Jordanian defensive positions during the 1967 Six-Day War. Though the weapon was phased out of frontline IDF service in the 1980s, some Uzis and Uzi variants were still used by a few IDF units until December 2003, when the IDF announced that it was retiring the Uzi from all IDF forces.[3]

In general, the Uzi was a reliable weapon in military service. However, even the Uzi fell victim to extreme conditions of sand and dust. During the Sinai campaign of the Yom Kippur War, IDF army units reaching the Suez reported that of all their small arms, only the 7.62 mm FN MAG machine gun was still in operation.

The Uzi proved especially useful for Mechanized infantry needing a compact weapon, and for infantry units clearing bunkers and other confined spaces. However, its limited range and accuracy in automatic fire (approximately 50 m) could be disconcerting when encountering enemy forces armed with longer-range small arms, and heavier support weapons could not always substitute for a longer-ranged individual weapon. These failings eventually caused the phaseout of the Uzi from IDF forces.[3]

The Uzi was also used in various conflicts outside Israel and the Middle East during the 1960s and 1970s. Quantities of 9 mm Uzi submachine guns were used by Portuguese cavalry, police, and security forces during the Portuguese Colonial Wars in Africa.

Design

The Uzi uses an open bolt, blowback-operated design. The open bolt design exposes the breech end of the barrel, and improves cooling during periods of continuous fire; however, it means that since the bolt is held to the rear when cocked, the receiver is more susceptible to contamination from sand and dirt ingress. It and the Czechoslovakian series 23 to 26 were the first weapons to use a telescoping bolt design, in which the bolt wraps around the breech end of the barrel.[1] This allows the barrel to be moved far back into the receiver and the magazine to be housed in the pistol grip, allowing for a heavier, slower-firing bolt in a shorter, better-balanced weapon.


The weapon is constructed primarily from stamped sheet metal, making it less expensive per unit to manufacture than an equivalent design machined from forgings. With relatively few moving parts, the Uzi is easy to strip for maintenance or repair. The magazine is housed within the pistol grip, allowing for intuitive and easy reloading in dark or difficult conditions, under the principle of 'hand finds hand'. The pistol grip is fitted with a grip safety, making it difficult to fire accidentally. However, the protruding vertical magazine also makes the gun awkward to fire when prone.

When the gun is de-cocked, the ejector port closes, preventing entry of dust and dirt. Though the Uzi's stamped-metal receiver is equipped with pressed reinforcement slots to accept accumulated dirt and sand, the weapon can still jam with heavy accumulations of sand in desert combat conditions when not cleaned regularly.

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.
