?'''Bow Machinegun''' - Forward-firing axillary weapon intended to protect the tank from infantry at short ranges. Usually mounted in a flexible ball mount to provide at least some field of fire, however since it was generally used for suppression fire, some tanks mounted bow machinegun in a fixed mount, fired by driver and set to hit the ground 200-300 meters in front of the vehicle.+

 '''Fuel Tank''' - Storage of the fuel for the '''engine'''. Always source of trouble, as it is storage of highly flammable material - usually found wherever there is enough free space and still not enough, some tanks mounted also external fuel tanks. Diesel fuel is somewhat harder to catch fire than petrol, but in turn, such fire is also harder to put. Damaged fuel tank increases the risk of fire on subsequent hits. '''Fuel Tank''' - Storage of the fuel for the '''engine'''.

 '''Muzzle Brake''' - Device redirecting part of propellant gases at the muzzle of the gun to reduce recoil. While muzzle brake can take away as much as 70% of gun recoil, thus enabling for faster target acquisition after shooting and reducing stress on vehicle, it causes other problems connected with the sound volume and muzzle blast magnitude. '''Muzzle Brake''' - Device redirecting part of propellant gases at the muzzle of the gun to reduce recoil.

?'''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.+'''Gun, Close Support''' - Based on the WWI experience, tanks were supposed to provide close support to attacking infantry.

Thus, at 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.+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.

?'''Gun, Tank''' - Any gun specifically modified to be mounted in a tank. Due to different priorities, even exactly same guns may often vary sigbnificantly, both in the construction of their breech and in the recoil mechanism - this is because the artillery usually has little space constraints, whereas tank turret internal volume is a very definite one. +'''Gun, Tank''' - Any gun specifically modified to be mounted in a tank. Due to different priorities, even exactly same guns may often vary significantly, both in the construction of their breech and in the recoil mechanism - this is because the artillery usually has little space constraints, whereas tank turret internal volume is a very definite one.
?As an example of "tank-specific" changes, an evolution of US 76mm M1A1C gun can be taken. The original intent was to fit a 3-inch 76mm gun M7, used in Tank Destroyers and Heavy Tank M6, into a Sherman turret, but it was soon found that neither the recoil mechanism, breech or ammunition allow easy operations int he strict confines of tank turret. A new gun was thus designed, using a new ammunition - while projectiles were the same, cartridges were shorter and fatter, to give the same volume of propellant and thus the same muzzle velocity. Thus 76mm Gun M1 was created, and after shortening the barrel it became the ubiquitous M1A1/M1A1C, capable of being mounted in tanks.+As an example of "tank-specific" changes, an evolution of US 76mm M1A1C gun can be taken.

 '''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. '''Gun-Howitzer''' - Artillery weapon, combining properties of field guns - long barrel, high muzzle velocity - with howitzers.

 '''AP''' - ''Armor Piercing'', ammunition type dedicated to penetrating enemy armor and thus disabling a tank. Often used as blanket term covering all various kinetic energy full-bore projectiles, "classic" AP shot was made of solid metal with no filler nor composite structure, relying only on its mass to penetrate and do sufficient damage to the enemy tank. While most WWII countries used ''APHE'', the United Kingdom preferred to use solid shot and while theoretically tests showed some difference in the internal damage of target tank, in real condition it usually did not matter. '''AP''' - ''Armor Piercing'', ammunition type dedicated to penetrating enemy armor and thus disabling a tank.

? 
?'''APBC''' - ''Armor Piercing, Ballistic Cap'', variant of ''AP''/''APHE''. Penetratiojn-optimised shape of AP projectile was not the most aerodynamic, especially with blunt-nosed projectiles (such as 122mm BR-471B). To improve aerodynamics and thus long-range stability, ballistic cap from a light metal was added to the projectile. 
? 
?'''APC''' - ''Armor Piercing, Capped'', ammunition type designed for better penetration of face-hardened armor. Shell nose was covered with a soft cap that deformed upon impact, distributing energy to larder part of the shell so the nose did not shatter. APC shells often showed less penetration against homogenous armor, but performed better against hardened one. Cap also, in some cases, eased penetration of sloped armor. 
? 
?'''APCBC''' - ''Armor Piercing, Capped, Ballistic Cap'' - combining ''APC'' and ''APBC'' advantages, APCBC provided both long-range stability of APBC and good perdormance vs. hard armor of APC. Used by most armies of WWII except for the USSR, where APBC with blunt-nosed penetrator was preferred. 
  
 '''APCR''' - ''Armor Piercing, Composite, Rigid'', basic ''subcaliber'' armor-piercing ammunition. APCR body consisted of a penetrator, with significantly smaller diameter than the bore, and of light metal casing around it, to fill up the bore. The light metal part was non-detacheable. Lighter mass gave the projectile higher muzzle velocity and higher penetration, however small sectional density gave by light weight, but full bore diameter, caused high drag and APCR lost velocity rapidly. APCR was used by all major players in WWII. '''APCR''' - ''Armor Piercing, Composite, Rigid'', basic ''subcaliber'' armor-piercing ammunition.
