The 20mm caliber is a size of cannon ammunition, most of which are shells carrying some kind of payload and an explosive fuse. Being a military cartridge, it is typically only available from Old World military bases and cannot be crafted.

This is a custom ammunition type created especially for the NIF-Bashed Weapons Mega-Pack.

Types

There are four varieties of 20mm ammunition available:

• 20mm Target Practice – An inert projectile typically used for training purposes, but still deals considerable ballistic damage to targets.
• 20mm Armor-Piercing Incendiary (API) – A high-velocity projectile designed to punch through armored targets. (-15 DT, 0.95x Damage).
• 20mm High-Explosive Incendiary (HEI) – An explosive projectile that detonates on impact and sets the target on fire.
• 20mm Semi-Armor-Piercing High-Explosive Incendiary (SAPHEI) – A multi-purpose projectile that punches through armor (-15 DT, 0.95x damage) and also explodes on impact, setting the target on fire.

Usage

The following Mega-Pack weapons can fire this ammunition:

• 20mm AutoCannon
• Anti-Tank Cannon
