# Shell

One round of ammunition, carrying its own damage, penetration, velocity and behaviour against armor.

Also known as round, ammo, ammunition.

A gun fires from a limited [ammunition rack](/glossary/ammo-rack.md), usually loaded with a mix of shell types. Which one is loaded changes almost everything about the shot: how much [armor](/glossary/armor-thickness.md) it defeats, how it behaves against angles, how fast it travels and what it costs.

Most vehicles carry a standard [armor-piercing](/glossary/armor-piercing.md) type as their working round, a premium round for targets they cannot otherwise hurt, and a few [high explosive](/glossary/high-explosive.md) for soft targets and base resets.
