The M1161 Growler is an Internally Transportable-Light Strike Vehicle (ITV-LSV) designed specifically for use with the V-22 Osprey tiltrotor aircraft. Fulfilling multiple roles of Light UtilityLight Strike and Fast Attack vehicle, it is smaller than most international vehicles in the same role. The Growler has taken over all duties of the M151 Jeep variants and completely replaced the Interim Fast Attack Vehicle(IFAV). The United States Special Operations Command (USSOCOM) has expressed interest in a modified version. A separate Marine variant, the M1163 Prime Mover is a combination 120mm mortar and integral ammunition trailer.
