Notes: This elderly antiaircraft gun is still in use by French Foreign Legion units, usually in a ground support role, and by the forces of Chad. It is preferred by the Legion due to its light weight and low recoil forces, which made it suitable for employment from relatively light vehicles. It uses the same M 693 autocannon used by the Cerbere 76T2, Tarasque 53T2, and the 53T4. Sighting equipment includes a reticule sight for antiaircraft use and a 5.2x telescopic sight for use against ground targets.

Notes: This is an older French antiaircraft gun, using the same autocannon (M 693(F2)) that the Cerbere 76T2 twin 20mm gun uses. It is a low-weight weapon that can be easily mounted on light trucks or towed behind smaller vehicles. The traverse and elevation mechanisms are driven by a hydraulic motor. As with the 53T1, the sights are a basic reticule sight for antiaircraft use and 5.2x telescopic sight for use against ground targets.

Notes: This is a double autocannon version of the Giat 53T2 antiaircraft gun above. It is otherwise the same as the 53T2, except for a more beefy, stable mounting and hydraulic recocking of the guns when loading them. In addition, the guns have automatic electric cutout to stop a gun from firing if it cooks off, and the gun can be set to not fired if pointed within certain arcs (to prevent firing at friendly targets or at useless fields of fire such as targets the ammunition cannot penetrate). As with most French antiaircraft autocannons, the gun includes a 1x reticule gunsight for antiaircraft use and a 5.2x telescopic sight for ground targets.

Notes: This is basically the German Rheinmetall Twin 20mm System with the Rh-202 autocannon replaced with M-693(F2) autocannons like those mounted on the 53T2 and 53T4. The 76T2 is designed to work in concert with the Crotale SAM missile system, and can use the same radar as the Crotale. It is also designed to be used with a helmet-pointing system (where the gunner directs the guns by looking at a target through a visor in a specially-equipped helmet). This helmet system, known as the DALDO, had not been bought by any country as of 2000, but is for sale.

Notes: The Giat Type 20 M621 is an electrically controlled 20mm autocannon designed for use on light vehicles and helicopters. It is capable of semiautomatic and automatic fire. An attached electrical box controls the selective fire aspects and burst length. It is mounted on light vehicles such as the Land Rover as well as helicopters such as the Puma, Gazelle, and boats. Turrets have also been devised with this gun. It can accept most sights and night vision equipment designed for use with automatic weapons.

Notes: This is a Giat 53T4 antiaircraft gun (detailed in the Heavy Weapons Handbook) with the twin 20mm autocannons replaced with a single 25mm Giat M811 autocannon. The mount is substantially the same with small changes to handle the new autocannon, and the ammunition box is somewhat larger, but also mostly the same.

Notes: This is an externally powered autocannon with a dual-feed mechanism. The feed direction is selected before firing a burst by flicking a switch. It can be placed on any mount that can normally accept a French 20mm autocannon, and turret mountings also exist.

Notes: This autocannon uses a mechanism similar to the 25mm Chaingun. The cannon comes with an electronic control and power unit, and has a rate of fire up to 1-750 rounds per minute. The Type 30 M 781 is a dual-feed weapon. It was designed principally as helicopter armament, but a ground/vehicle mount does exist. Weight given is with the mount.
