Automated turret (Fallout: New Vegas)

Variants
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. For conversation and reference purposes, odd-numbered turrets (Mark I, Mark III, etc.) are ceiling-mounted, bullet firing turrets, while even numbered turrets (Mark II, etc.) are ground-mounted, laser turrets.
