AutoCannons

AutoCannons are a a type of direct-fire ballistic weapon, normally firing HEAP (High-Explosive Armor-Piercing) rounds at targets either singly or in bursts.

Some autocannons can use special munitions that modify the properties of the shot.

Autocannon ratings
Different manufacturers and models of autocannons have different calibers (25mm-203mm) and rates of fire. Due to this, autocannons are grouped into generic "classes" of autocannons with common damage ratings, with Autocannon/5s usually having a long range with a small to moderate damage level.

An example of the rating system: the Crusher Super Heavy Cannon is a 150mm weapon firing ten shells per "shot", while the Chemjet Gun is a 185mm weapon firing much slower, but causing higher damage. Despite their differences, both are classified as Autocannon/20s due to their damage output.
