Interim Fast Attack Vehicle

The Interim Fast Attack Vehicle (IFAV) is a reconnaissance vehicle deployed and used by the United States Marine Force Recon and Marine Expeditionary Units. Force Recon used to operate a fleet of Desert Patrol Vehicles (formerly known as Fast Attack Vehicles or FAVs for short), popularized by the Navy SEALs as the "black dune buggy." However, this vehicle lacked cargo capacity and firepower, so Force Recon moved to a militarized Mercedes-Benz G-Class, also known as a G-wagen, 290 GD Turbodiesel 4×4, a much more traditional "Jeep" type truck.
