'''Armor Piercing Rounds'''<ref>''[[Halo: Ghosts of Onyx]]'', Prologue</ref>, alternately spelled as '''Armour Piercing Rounds (UK Spelling)''' and colloquially known as '''AP rounds''', are the type of ammo used in most small arms [[weapons]] like [[Assault Rifles]] used by the [[United Nations Space Command]]. When all the AP rounds in a weapon are used up, some personnel switch to [[Shredder Rounds]], as the [[SPARTAN]]s of [[Blue Team]] did on a mission in the [[Lambda Serpentis System]]<ref>[[Halo: The Fall of Reach]], page 3</ref>.

'''Armor-piercing rounds''', colloquially known as '''AP rounds''', are a type of ammunition designed to penetrate armor.


AP rounds are tipped with a hard metallic cap. The cap can be made from tungsten, steel, a carbide of some sort, or even depleted uranium. This allows the bullet to pierce through [[armor]], as the projectile stays intact because the tip of the round does not deform enough to slow it down dramatically. Armor Piercing ammunition is designed to dump almost all of it's energy directly into the target, causing massive trauma and kinetic energy damage. The downside of AP rounds is that they perform poorly against [[energy shielding]].
==Overview==
Armor piercing rounds are used to penetrate hardened, armored targets, such as ballistic vests, vehicle armor, concrete, tanks, and other defenses, depending on the caliber, sectional energy, and length of the round. Armor piercing ammunition can use a cap of a dense, tough metal, or a core of it, or a mix of both. Modern AP ammunition consists of tungsten alloys, usually then surrounded in a lead or copper jacket, which allow it high potential against protected targets. The hard, dense construction prevents expansion, shattering, and deformation, granting much increased effect against armored opponents. The problem is that they 1, don't cause great injury, since the lack of yaw and deformation even after piercing an armor panel means little terminal effect, and 2, armor may still defeat the AP round.

In Halo, the disadvantage of AP rounds is that they perform poorly against [[energy shielding|energy shields]], as the shielding defeats the piercing qualities of the bullet. An AP round must thus rely simply upon its kinetic energy to deplete the shields before it can damage the shielded enemy. Large rounds, such as the [[12.7×99mm Armor-Piercing]] and the [[14.5×114 mm]], perform well under these conditions.

Armor-piercing rounds, colloquially known as AP rounds, are a type of ammunition designed to penetrate armor.

Overview[edit]

Armor piercing rounds are used to penetrate hardened, armored targets, such as ballistic vests, vehicle armor, concrete, tanks, and other defenses, depending on the caliber, sectional energy, and length of the round. Armor piercing ammunition can use a cap of a dense, tough metal, or a core of it, or a mix of both. Modern AP ammunition consists of tungsten alloys, usually then surrounded in a lead or copper jacket, which allow it high potential against protected targets. The hard, dense construction prevents expansion, shattering, and deformation, granting much increased effect against armored opponents. The problem is that they 1, don't cause great injury, since the lack of yaw and deformation even after piercing an armor panel means little terminal effect, and 2, armor may still defeat the AP round.

In Halo, the disadvantage of AP rounds is that they perform poorly against energy shields, as the shielding defeats the piercing qualities of the bullet. An AP round must thus rely simply upon its kinetic energy to deplete the shields before it can damage the shielded enemy. Large rounds, such as the 12.7×99mm Armor-Piercing and the 14.5×114 mm, perform well under these conditions. However, smaller AP rounds, such as the M118 7.62×51 mm and the M634 9.5×40 mm, are ineffective unless used in large quantities.
