The sides have no active armor, but also, judging by the size of the mounting hardware they do not appear to be armored beyond rifle ammo. It appears this is light, cheap, fast and disposable.

With modern anti-tank weapons, if you are armored enough to resist them, then you are too heavy to move, to heavy to cross bridges, and too heavy to transport by air. So you might as well scale back the armor to what will stop .50 cal and shrapnel.

I'm thinking the next-gen tank will be unmanned (controlled by somebody well behind it) but capable of serious firepower.
