It's interesting how similar problems have similar solutions in the resemblance between MRAP and some of the vehicles developed by South Africa and Rhodesia in their counter-insurgencies in the 70s and 80s...

If current predictions run true and this form of warfare is going to be the new 'regular' warfare for the next 2-3 decades, then I think you are correct. The risk may lie in going too far down the COIN vehicle path at the expense of the those optimised for traditional force-on-force conflict - much we we did in the 80s and 90s across NATO and ABCA...

The other risk with vehicles such as MRAP is that they will continue to be perceived in some quarters and 'anti-IED' vehicles which they are not...any vehicle designed to be anti-IED is only a reaction and not the response that CIED really needs...
