Automated turret (Fallout: New Vegas)

Automated turrets are automated, unmanned machine guns which are capable of sensing, and attacking targets that are hostile to the faction, or organization to which they belong.

Specifications
Automated turrets can rest on the floor or be mounted onto the ceiling. The ceiling turrets use bullet-based weaponry whereas the ground turrets are equipped with lasers, although some ground mounted bullet-based turrets were built. Both variants have unlimited ammunition.
