Notes: This cannon is found on a variety of vehicular and ground mounts, including the ZSU-23-4, BMP-23, and ZU-23-2 and ZU-23-4, as well as some Russian-invented aircraft. It was invented just after the Second World War, and very few changes have been made to the design or ammunition since then.

Notes: This is a towed mounting of two ZU-23 autocannons. It was designed initially to replace the ZPU-2 double KPV machinegun mounting, but ended up merely supplementing that weapon at best. In the Russian military and that of most former Warsaw Pact countries, the ZU-23-2 ended up being mostly replaced in turn by the SA-9 Gaskin surface to air missile. The ZU-23-2 is, however, very common in the world, particularly in former Russian and Chinese client states and in Israel and South Africa (where captured examples were put to use). In many of those countries, the towed systems have had their wheels removed and they are mounted on the backs of trucks or light armored vehicles.

Notes: This Russian autocannon is mounted on several Russian and former Warsaw Pact vehicles, including the BMP-2 and BMP-3. It is a long-barreled, gas operated, dual-feed weapon that may be fired at a ROF of 3 or 5.

Notes: This is a very old weapon developed before World War 2 and never upgraded in any significant manner over the years. Despite this fact, and that it is of very limited usefulness against modern aircraft, it is widely used throughout the world. The basic gun includes an AV2 gun shield, but it is removed by most countries since it severely limits the depression of the gun, and the M-1939’s best use today is as an antipersonnel and anti-light-vehicle weapon. (It also reduces the weight of the gun by about 100 kilograms.) There are one and two-gun mounts of this weapon. The M-1939 is known to be in service with at least 43 countries today, but Russia is not one of them.

Notes: A magazine fed autocannon, this is a towed version of the gun found on the ZSU-57-2. The weapon is fed from a 4-round magazine, and can be kept continually firing by a diligent crew feeding clips into it. The S-60 is designed to be hooked into fire control radars used by various SAM missile systems, to be used in conjunction with the missiles for an integrated air defense network.
