The Autocannon is a direct-fire ballistic weapon, firing HEAP (High-Explosive Armor-Piercing) rounds at targets either singly or in bursts.

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/10s causing more damage than lower-caliber autocannons while retaining a moderate range.

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.

The Terran Hegemony introduced a prototype AC/10 in 2445. It cost five times as much as a standard Autocannon/10, would jam like an Ultra Autocannon, and only carry 8 reloads per ton of ammunition.[2]

An Autocannon/10 can use special munitions to increase its effectiveness.
