The ACU Trooper was a member of Jurassic World's Asset Containment Unit.
He is portrayed by Timothy Eulich.
Before coming to work in the ACU, he had served as a soldier in the US Army in Afghanistan.
He was with Simon Masrani in JW001 during Masrani's attempt to hunt and kill Indominus rex from the air. He sat up front with Masrani. Masrani asked him and the other trooper riding with them if they'd served in the military, and asked if their general ever flew with them.
When Indominus rex broke through into the aviary, it unleashed a horde of Pteranodons and Dimorphodons, which swarmed the helicopter. As Masrani struggled to control the craft, the gunner fell out and was carried away by a Pteranodon, while another Pteranodon thrust its beak through the helicopter's windshield, impaling the ACU trooper through the chest, killing him instantly. His body was still strapped into its seat as the copter crashed through the aviary dome, fell to the ground and exploded.
