The M181 Cougar Armoured Security Vehicle (ASV) is an internal security vehicle produced for the UNSC Defence Force by AMG Transport Dynamics, based roughly upon the M12 "Warthog" Force Application Vehicle. Its armament primarily consists of two M460LB grenade launchers and an M247 machine gun mounted coaxially within the gunner's turret. A second M247 machine gun is pintle-mounted on the gunner's hatch. In this role the Cougar met significant successes, and, coupled with armour-kitted M12 Warthog vehicles, formed the basis for UNSC light transportation for the remainder of the Insurrection.
