Well, this is certainly a unique tank design, and definitely one f the most heavily armed, although it is nearly impossibly to tell exactly how large this thing really is. Maybe it's the camera angle, but it looks small to me. Like, probably 5 to 6 meters in length. Although, I think that feels also comes from the tread design. If I were designing this, I would've left the treads as single-tracked, as opposed to double-wide. Mainly because, while the segmented, hinged drive-train is unique and would certainly improve on mobility issues present in traditional tanks, the extra width means extra friction that whatever system is used to turn must overcome to do the actual turning. Also, you might consider lengthening the tracks so that they lead the vehicle, and making them deeper to give the vehicle greater clearance for potential hazards and obstacles. Also, the leading edges of of tank treads are usually fairly large, so that the engine doesn't have to strain with using a smaller surface to begin an angled ascent (steep hill)... Unless this is intended as an urban vehicle, which I kinda get the feeling that it is, given the lack of a large main gun, and several smaller batteries that have the appearance of energy-weapon apertures. What with the hexagonal and square barrels. Also, am I seeing a pair of radioisotope thermoelectric generator (RTG's) near the rear (self-contained nuclear generators)?
