Notes: This is the 20mm autocannon most commonly found on South African vehicles, boats, and aircraft, such as the Casspir, RG-32 Scout/Weapons Carrier, and Rooivalk helicopter. It may be mechanically or electrically fired, and ground and pintle mounted versions include the Armson Occluded Eye Gunsight, a 3.5x sight designed for the extreme vibration of heavy weapons such as heavy machineguns, grenade launchers, and autocannons. The GA1 may be mounted on an NHT for ground use, or in equivalent mounts for pintle use.

Notes: The GAMA (Gun Automatic Multiple Ammunition) is a variant of the GA1 that employs a series of interchangeable barrels and feed mechanisms to fire a large amount of ammunition types. The weapon is issued as a kit containing the barrels and receiver groups. It was first developed to allow the user to train with cheaper smaller caliber ammunition, but was then further developed to give the user greater utility with the weapon.

Notes: This South African autocannon is based on the French M-693. It is a smaller autocannon, useable on NHT or pintle mounts as well as being the main armament on the Ratel 20 APC. It is electrically fired by a battery, generator, or vehicle power. It can be installed upright, upside down, or on its side without affecting its performance. It is a dual feed weapon, in which two belts of ammunition may be loaded into the weapon, and the belt fired being selected by a flip of a switch.

Notes: This is towed antiaircraft gun system based around the GA-35 autocannon. It is a surprisingly lightweight system for its size, and computer studies suggest that three of these guns are more effective than two double-barreled 35mm Oerlikon GDF systems (now standard in South Africa). The fire control system includes a periscopic sight with a magnification of 5.2x, a laser rangefinder with a ballistic computer, and a Doppler muzzle-velocity measuring system. The gun is fed by two 55-round belts contained in magazines on either side of the receiver. Unfortunately, with the end of arms sanctions to South Africa, the South Africans were able to obtain cheaper antiaircraft weapons from foreign sources and development of the eGLaS 35 stopped; the system is for sale, however.

Twilight 2000 Notes: About 50 of these weapons were deployed during the Twilight War.

Merc 2000 Notes: This weapon is a pretty good seller.
