One of my favourites. They dropped the ball in many areas with regards to ME3 though, apart from the Citadel DLC. ME2 is in my opinion the best mix of aspects in the series and I would definitely recommend it. Best to play the first game as well, though, since it opens up a lot more things in the sequel.
while this is one bad-a APC, the design of the weels would make ti excessively easy to render immobile, at which point it become a glorified 100mm cannon. painful to get rid of, yes, but stationary generally results in dead.
Well, in terms of survivability it operates similar to current MRAP vehicles, including the irl Mastiff, where the wheels would blow off.
However, since the wheels on this vehicle extend out a way from the body and a good amount of space is available, as opposed to the blast going straight into the suspension or being trapped by the arch, it should resist the blast more effectively as the energy is dispersed more. Couple that with some very strong structural materials and the wheels will be hard to lose. Of course, the IED or mine would have to pass detection by the rather larger sensor array or onboard AA first.
As for external attack they are again very resistant. Aside from the armour cladding the wheel assembly, we have the kinetic shielding and a DEW active protection system (the little box next to the main gun in the turret). A direct hit from a big or explosive enough round will do some serious damage, but with the full protective package, coupled with its speed and manoeuvrability, it shouldn't be anymore vulnerable than other vehicles of the class, less so maybe. If it hits a central wheel, all is not lost. They can either jettison or retract it. Or if you have a river or body of water handy, simply boat away.
I did consider giving it some retracted running wheels or treads, similar to those of a BRDM, in the event that it lost a wheel or wheels, but couldn't work them in properly.
It's designed for rapid assault more than anything, relying on its speed to keep out if trouble. The setup also helps it deploy from aircraft with only a drogue chute for stability. Plot calls for one of these, packed with the main cast, dropping from the back of a Slamfist as it flies 50ft off the deck.
