Mine-Resistant Ambush Protected (MRAP) is a term for United States military vehicles produced as part of the MRAP program that are designed specifically to withstand improvised explosive device (IED) attacks and ambushes.
This kind of vehicles have a modified chassis and a highly armored bodywork, to protect their crew from the explosions of mines and IEDs
The same features that make them immune to direct explosions (the tough chassis, reinforced windows and bodywork, etc.) make it the perfect transport during a zombie incident, because it have the resistance to cross hordes of zombies without major problems, but without Compromise the speed or maneuverability of the vehicle.
The MRAP combines the resistance of an APC with the speed and maneuverability of a Hummvee, as well as the simplicity to drive one of these, because it operates as a conventional vehicle and it is enough to have basic driving skils and time of practice to operate it efficiently.
