+'''Automatic Cannon''' - Rapid-fire weapon of 20mm or larger caliber. Used in early-war light tanks to give them edge versus their (byy then) machinegun-armed opponents. However, quick shell-vs-armor race left automatic cannons rapidly behind and used only by few specialised German reconnaissance vehicles. However, automatic cannons vastly expanded in the region of anti-aircraft defense.
+Typical examples: 20mm KwK 38, 20mm TNSh
+'''Gun''' - Generally a shot or shell-firing weapon using lower register (below 45°) for direct fire, most often falls into following categories:
+'''Gun, Anti-Tank''' - Self-explanatory. Antitank guns are designed with one main purpose in mind, and that is to punch holes into armored targets. The main aim of such gun is to fire a high-velocity shell at very flat trajectory and, if possible, accurately. To achieve this, antitank guns have usually long barrel (50-70 calibers or more). This however means that even HE shells have to have thick walls and thus carry often less explosives.
+Many anti-tank guns started their career as something else, usually as field or anti-aircraft guns, ie applications which also needed high shell velocity and accuracy.
+Typical examples: 57mm ZiS-2, 75mm PaK 39, 88mm PaK 43
+'''Gun, Close Support''' - Based on the WWI experience, tanks were supposed to provide close support to attacking infantry. For that purpose, it was important to have a relatively large-caliber weapon (to get a good HE payload), but muzzle velocity was not as crucial. Thus, on the beginning of the war, most countries employed fire support tanks with a low-velocity gun or howitzer. French army even based the entire doctrine around this concept.
+Close support guns came usually in calibers from 37mm to 76mm, with rather short barrels (around 20 calibers or even less) and low muzzle velocity. Due to rapid advances in armor protection, they became obsolete very quickly and armies still using them had to deploy HEAT shells with them to keep them atleast marginally useful in combat against other armored targets.
+Typical examples: 75mm KwK 37
+'''Gun, Conical''' - Usually referred to as taper-bore or squeezebore gun, it was a special category of anti-tank guns designed to provide high penetration without the use of special (and expensive) materials such as tungsten carbide, as well as to remove range limitations of APCR projectiles. Taper-bore guns used barrel with changing diameter, from original caliber to significantly smaller one, thus reducing the cross-section and drag of the projectile to extend its effective range.
+'''Gun, Field''' - Artillery weapon, used for direct or indirect fire in lower register. Usually longer range than same caliber howitzers, in smaller calibers often firing fixed charge (fixed amount of propellant) to achieve high rates of fire, at the cost of larger dead zones. Light field guns were also often pushed to anti-tank duty, thanks to their high muzzle velocity resulting in good penetration. Conversely, obsolete antitank guns often wound up acting as field guns.
+Typical examples: 76mm ZIS-3, 76mm PaK 36(r), 155mm M1A1
+'''Gun-Howitzer''' - Artillery weapon, combining properties of field guns - long barrel, high muzzle velocity - with howitzers. Thanks to variable charge it is able to act as both, and since its advent it gradually proceeded to cancel both categories. Almost all weapons currently called "Howitzers" are, in fact, gun-howitzers.
+In-game, there is what is considered the first gun-howitzer of any significance. The 152mm ML-20 gun-howitzer served not only in artillery battalions, but also as a heavy direct-fire weapon in SU-152 and ISU-152 assault guns.
