Auto-Cannon (Fallout Tactics)

The auto-cannon is an autonomous defence turret equipped with twin minigun cannons and relatively heavily armoured. They are usually part of an automated defense system.

They can be found at such locations as Navarro, just like the gun turret and can also be found in such pre-War locations as the Sierra Army Depot.

Fallout Tactics
In Fallout Tactics there are a very similar turrets though they only have one barrel and some of them shoot rockets. They are met all around on the later missions.
