The new GT500 is revealed in another shade of green....
It can't have much more armor than it does and still retain mobility. There's always a trade off, seems like you may already know that. Back when this thing was designed, IEDs weren't a thing.

While it’s true the Stryker was designed before the proliferation of IED’s in Iraq circa 2004-2005, land mines have existed for decades before its design. A V shaped hull would increase survivability from a blast underneath. It sucks that we rolled out a new troop transport vehicle only for it to be a liability once it hit the battlefield just a couple years later. And yes it was intended to fight on a conventional battlefield and not in a COIN environment but they should have had a little foresight in the design process to include a V hull at least.
I think V hulls have dimension issues when trying to fit on aircraft transport.
