M1939 & SGM

The 37 mm automatic air defense gun M1939 was a Soviet 37 mm caliber anti-aircraft gun developed during the late 1930s and used during World War II and the cold war. Guns of this type were successfully used throughout the Eastern Front.

Total Soviet production was around 20,000 units, ending in 1945. The gun and its ammunition also continued to be produced in Poland, China, North Korea and Egypt. The projectiles themselves are identical to those fired by the NS-37 aircraft cannon. Although never as effective as the bofor gun, especially against fast jets, the m1939 was used in many of the conflicts of the cold war, including the Arab-Israeli wars.

The SG-43 Goryunov was a Soviet medium machine gun that was introduced during the Second World War as a replacement for the older M1910 Maxim machine guns. It was mounted on wheeled mounts, tripods and armored vehicles.

After the end of World War II, the SG-43 was improved and renamed SGM; dust covers and a new barrel lock were fitted, and a splined barrel was fitted to improve cooling. The SGM was widely exported and also licensed for construction in several countries, including Egypt. Egypt and Syria have used the SGM until its replacement by the PK machine gun.

The FN MAG is a Belgian 7.62 mm general-purpose machine gun, designed in the early 1950s at Fabrique Nationale (FN) by Ernest Vervier. It has been used by more than 80 countries, and it has been made under licence in several countries. The MAG is available in three primary versions: the standard, infantry Model, the coaxial machine gun for armoured fighting vehicles and the mounted version for vehicles and static positions.

The IDF used the infantry model as thier standard machine gun for many years. It gradually began to replace the M1919 Browning Machine gun as a static and mounted machine gun on vehicles such as APCs, jeeps and helicopters.
