It's just too big and with way to low armor for any troop transport in a high-intensity combat area or tank-hunting role, meaning the turret will rarely be of any use. Anything that is worth shooting with that 120mm gun and that big turret will make a short work of your hull, not even taking into consideration the internal space used by the turret ring and mechanisms, and the massive weigh of that 1600mm frontal armor. It would be much more credible with a lower caliber unmanned teleoperated turret . The overall look is great and your modeling skill is flawless, and for the "rule of cool" look, i give you a 10/10, but considering how much effort you but in the technical data and overall plausibility of your wonderful vehicles, this one is not as likely as many of the others.
