At times, I think the military can't live without their much vaunted uparmored anything. If you carry moire armor, the bad guys simply build a bigger IED to knock it out.

That, or go with two vehicles: one that is used for areas/missions that do not require armour out the wazoo and another vehicle that is armoured.
