These are the guys who will be showing up on doorsteps, with a battering ram and flash-bang grenades.
Since MRAPs are design against bombs, and have a fire suppression system, the logical way to attack them is with a water filled tiger trap. Simple enough in concept, a deep pit with a waterproof cover that can handle up to about 10 tons of weight, but collapses with more than that. An MRAP weighs about 14+ tons. Plunk. The USMC reported that water accidents of this sort were very dangerous for MRAPs due to their high center of gravity.
