The ACU Gunner was a member of Jurassic World's Asset Containment Unit.
He is portrayed by Kevin Foster.
When Simon Masrani took it upon himself to kill Indominus rex after the ACU's initial failure and the death of Katashi Hamada, he attaches a GE M134 minigun to JW001, which is manned by the ACU gunner. Masrani flew the helicopter in pursuit of Indominus, but the gunner failed to hit her.
When Indominus broke through the aviary dome and freed several Pteranodons and Dimorphodons, these winged reptiles flew up towards JW001 and attacked the copter. As the helicopter was attacked by the Pteranodons, the gunner managed to shoot down 1 of the flying reptiles, but another slammed into the chopper, causing him to slip out. He manages to save himself by grabbing the M134, but a swooping Pteranodon snatched and presumably killed him.
