Cartridge, Caliber 5.56 mm, Armor Piercing, M995 [Black tip]: 5.56×45mm 52-grain AP cartridge with a tungsten core. Cartridge, Caliber 5.56 mm, Tracer, XM996 [Crimson tip] : So-called "Dim Tracer" with reduced effect primarily for use with night vision devices.
The .30 caliber (7.62 mm) armor-piercing bullet on the right has a copper jacket enclosing a hardened penetrator, but externally resembles the other four lead-core bullets. Armor-piercing bullets for rifle and handgun cartridges are designed to penetrate ballistic armor and protective shields intended to stop or deflect conventional bullets.
Similarly to SLAP rounds (saboted light armor penetrator) which get their armor-piercing ability from the propulsion of a 7.62 mm tungsten heavy alloy bullet from a 12.7 mm barrel (.50 caliber) using a sabot with much more energy than is usually possible from a 7.62 mm round, HEIAP munitions utilize a similar theory with an added explosive ...
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. [1]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.
Note every fifth round is a red-and-silver-tipped armor-piercing incendiary tracer round (M20). 7.62×51mm NATO Orange-tipped FMJ tracer ammunition in a five-round stripper clip A tracer projectile is constructed with a hollow base filled with a pyrotechnic flare material, made of a mixture of a very finely ground metallic fuel, oxidizer , and ...
The 7N22 armour-piercing bullet, introduced in 1998, has a 1.75 g (27.0 gr) sharp-pointed steel penetrator made of steel U12A and retains the soft lead plug in the nose for jacket discarding. 7N22 boat-tail bullets weigh 3.69 g (56.9 gr) and can be identified by their red identification ring above the cartridge neck and a black tip.

The current NATO 5.56mm SS109 (M855) bullet uses a steel-tipped lead core to improve penetration, the steel tip providing resistance to deformation for armor piercing, and the heavier lead core (25% heavier than the previous bullet, the M193) providing increased sectional density for better penetration in soft targets.
The saboted light armor penetrator (SLAP) family of firearm ammunition is designed to penetrate armor more efficiently than standard armor-piercing ammunition. In the US it was developed by the Marine Corps during the mid/late 1980s and was approved for service use in 1990 during Operation Desert Storm .
