Rangers were seen patrolling outside of Paddock 11 when Claire Dearing brought Simon Masrani to view the Indominus rex. Two were present at the Raptor Research Arena when Leon fell in. Although they prepared to fire their non-lethal taser rifles at the Velociraptors, Owen Grady stopped them, telling them that if they shot at the animals they'd never trust humans ever again. The rangers relented, and Owen rescued Leon by himself. Rangers later assisted in the mass evacuation of the surviving visitors and personnel from Isla Nublar.
