My biggest hope for tanks is that is that they use a damage model similar to the old WWIIOL. As in as much realism as possible. It is possible shell goes right on through hitting nothing. Pens generate shrapnel and even bounces causes spall. The only way to destroy a tank is to kill everything inside or explode the thing. Realistic insides of the tank for damage model purposes such as locations of the engine, fuel tank, ammo rack, etc.
Also, I imagine there being historical and arcade, possibly full real like with planes. In arcade, I would guess there are smaller maps and a more WOT like gameplay with repairing tracks and other parts of the tank. In HB, you get larger, more realistic maps and the full damage model where if you get tracked you are either stuck there or possibly be able to send out the crew to repair it (unlikely). In FRB I would guess that you have the full sized maps, but you are stuck with the view from inside the tank and no markers, similar to the current plane FRB. Another thing I have hopes for is also the WWIIOL spotting system, which is to say no spotting system. It is your job to keep a look out for enemies, no magical flashing sign over their head if get near enough to them but instead they are always there and it is up to you to spot them.
Anyways, thoughts on that? How do you all think Army is going to work out?
