APCBC
Armour-piercing, capped, ballistic capped (APCBC) is a type of configuration for armour-piercing ammunition introduced in the 1930s to improve the armour-piercing capabilities of both naval and anti-tank guns. The configuration consists of an armour-piercing shell fitted with a stubby ''armour-piercing cap'' (AP cap) for improved penetration properties against surface hardened armour, especially at high impact angles, and an aerodynamic ''ballistic cap'' on top of the AP cap to correct for the poorer aerodynamics, especially higher drag, otherwise created by the stubby AP cap. These features allow APCBC shells to retain higher velocities and to deliver more energy to the target on impact, especially at long range when compared to uncapped shells. The configuration is used on both inert and explosive armour-piercing shell types: *Armour-piercing (AP), capped, ballistic capped (APCBC) * Semi-armour-piercing (SAP), capped, ballistic capped (SAPCBC) * Armour-piercing, high-explos ...

Ordnance QF 17 Pounder
The Ordnance Quick-Firing 17-pounder (or just 17-pdr)Under the British standard ordnance weights and measurements the gun's approximate projectile weight is used to denote different guns of the same calibre. Hence this was a 3-inch gun, of which there were several types in British service, which fired a projectile weighing approximately was a 76.2 mm (3 inch) gun developed by the United Kingdom during World War II. It was used as an anti-tank gun on its own carriage, as well as equipping a number of British tanks. Used with the Armour-piercing discarding sabot, APDS shot, it was capable of defeating all but the thickest vehicle armour, armour on German tanks. It was used to "up-gun" some foreign-built vehicles in British service, notably to produce the Sherman Firefly variant of the US M4 Sherman tank, giving British tank units the ability to hold their own against their German counterparts. In the anti-tank role, it was replaced after the war by the 120 mm BAT recoille ...

Armor-piercing Capped Ballistic-capped High-explosive Tracer Example
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors. From the 1920s onwards, armour-piercing weapons were required for anti-tank warfare. AP rounds smaller than 20 mm are intended for lightly armoured targets such as body armour, bulletproof glass, and lightly armoured vehicles. As tank armour improved during World War II, anti-vehicle rounds began to use a smaller but dense penetrating body within a larger shell, firing at a very-high muzzle velocity. Modern penetrators are long rods of dense material like tungsten or depleted uranium (DU) that further improve the terminal ballistics. Penetration In the context of weaponry, ''penetration'' is the ability of a weapon or projectile to pierce into ...
