The Vulture has what appears to be a chaingun mounted on the underside of the craft as its only weapon. You first come across Vultures in Act 1, Chapter 2. You will find a warehouse/hangar full of them and are tasked with destroying them by shooting their fuel tanks. Vultures are involved with Skillshots such as Flak and Skyjack. The player can also leash the pilot out of the copter to kill him for the Parashoot skillshot.
