Anti-Aircraft Guns - Weapons designed for anti-aircraft defense. It is a weapon with bore diameter of 20 mm or greater. For anti-aircraft weapons of lesser bore diameter, please see Category:Machine Gun. Examples of the classification is 8.8 cm Flak 18/36/37/41 and 85 mm Air Defense Gun M1939 (52-K), the weapons were designed for anti-aircraft defense (the names suggest so). Even though the weapons in these examples were used for anti-tank combat, they are still anti-aircraft weapons.
Anti-Tank Guns - Weapons designed to fight against armored vehicles. Anti-tank guns are effective at short to medium range, as they are typically fired with a flat or nearly flat trajectory. The bore diameter is 20mm or greater. For anti-tank guns, the term caliber refers to the ratio of the barrel length to bore diameter. An example of a classification is the 8.8 cm Pak 43 gun, which is designed for anti-tank combat. It is worth remembering that the anti-aircraft weapon 8.8 cm Flak 18/36/37/41 which is adapted to anti-tank combat, but it is not an anti-tank weapon by design.
Autocannons / Rotary Autocannons - Automatic weapons with a caliber of 20 mm or greater, designed to be mounted on various platforms. In most cases, these are planes, helicopters or armored vehicles. Sometimes weapons of this type can be used for anti-aircraft / anti-tank defense by using special platforms. A good example of such a weapon is the M242 Bushmaster chaingun which was mounted on the M2 Bradley and by using a special platform it served as an anti-aircraft weapon as the Mk 38 Mod 2. There are also autocannons that are designed for anti-aircraft defense. For example, Breda Modello 35 is an autocannon. But in its basic form, it plays the role of an anti-aircraft weapon.
Howitzers - Weapons capable of shooting at short distances along a flat flight trajectory, and longer distances when the barrel is elevated. Howitzer barrels can be elevated up to around 70 °, depending on the specific model of howitzer. For howitzers, the term caliber refers to the ratio of the barrel length to bore diameter. An example of a howitzer is 122 mm howitzer M1938 (M-30) where the name itself indicates the type of weapon. Sometimes howitzers are also mounted on special platforms. An example of such a weapon is M102 Howitzer, which in the basic version is a towed howitzer, and through modifications it was mounted in AC-130 gunship aircraft
Infantry Support Guns or Battalion Guns - Infantry support guns or battalion guns are artillery weapons designed and used to increase the firepower of the infantry units they are intrinsic to, offering immediate tactical response to the needs of the unit's commanding officer. They typically have short, low-velocity barrels, and light construction carriages, allowing them to be more easily manouvered on the battlefield. They are generally used for direct fire, rather than the indirect fire of other types of artillery. Their role has generally been replaced by tanks using tank guns, infantry fighting vehicles using autocannons, other combat vehicles, mortars, recoilless rifles, rocket-propelled grenades and shoulder-launched missiles.
Naval Guns - Cannons mounted on ships. Sometimes mounted on the ground, they served as coastal defense weapons. The uses of this weapon are diverse. They were used both against ships and aircraft. An example of a naval weapon is the 5-Inch/38 Caliber Naval Gun. For naval guns and coastal guns, the term caliber refers to the ratio of the barrel length to bore diameter. It is also worth remembering that many cannons / automatic cannons have been adapted to the needs of the Navy. An example of such a weapon is 37 mm M1939 (61-K), it is an anti-aircraft weapon which, thanks to the use of a special platform, served in the navy as 37 mm 70-K in a single version and 37mm V-11 double-coupled version.
Tank Cannons - Cannons mounted on tanks and armored vehicles. In some cases, they are stationary mounted on special platforms. An example is the tank gun 5 cm KwK 39 L/60 mounted primarily on PzKpfw III tanks and on the Sd.Kfz.234 armored car. For tank cannons, the term caliber refers to the ratio of the barrel length to bore diameter. There are also cannons that have been specially adapted for use in tanks. An example is the 2 cm FlaK 30 autocannon, which was designed as an anti-aircraft weapon and after modification was placed in armored vehicles as 2 cm KwK 30.
