Boxer is one crazy monster. With protection "ueber alles".

Your 1000 men force: If you can speed across country like that, you seem to be unopposed. Guess then you could as well hire a local bus company.
Coffee on Red Square in the morning anyone?

Another thought: How many bombs can the bad guys plant along a hard to predict route (different from the easy to predict patrol routines in Iraqi towns)? Seems like there'd be more danger from RPGs. And these neither the MRAP nor the APC can withstand without reactive armor.

The running costs: Guess if you use an APC like a road-bound MRAP, your running costs - which are dominantly automotive then - shouldn't be too different.

Of course, if you have a vehicle designed for a narrow usage profile (road-use only), then it will be overall cheaper and better suited for that single task than a vehicle with a wider usage profile. But ok, let's not turn this into MRAP vs APC.

As a vehicle to move troops from one square to another, I think trucks (with aramid mats) are equally suited; plus they provide more cargo space, and better rough-terrain capability.
You could put a mortar into an MRAP, and NETFIRES, and ATGM and MANPADS launcher, and cut down the rear cabin and put an autocannon instead. But you will still remain road/piste-bound, which limits your mobility.
And: All these above jobs a truck can also do. Which is basically what Caesar, Bereg, Pantsir, &c do.

I just don't see much space for the MRAP between trucks and APCs.

Btw, the Wildcat was designed for the MPC competition. One of the more interesting MRAPs is the Rafael Golan. But it's still a riot-control vehicle.


PS: NOTHING is more screwed than V-22 and EFV!
