The Mine Resistant Ambush Protected (MRAP) vehicle is a light vehicle (not classified as an armored fighting vehicle) with added protection against improvised explosive devices, and the infantry ambushes that may follow. The hull of an MRAP is specifically designed to deflect explosions from buried munitions, riding higher above ground and featuring a sloped undercarriage rather than a traditional flat bottom.
Several vehicles used by the United States carry the MRAP designation. They're increasingly phasing out the HMMWVs in US-frontline-service. Among them is the Cougar, an American infantry mobility vehicle. The Cougar H Variant has four wheels.
