The choice to have your cannon offset is interesting, but I'd be concerned on the stress induced into the turret mechanism whenever you fire. The offset missile box could create a similar twisting effect on the turret. Came across your work while doing some research on APC design. Your 3D models are very clean and have the right kinds of angles to the armor plating for effective impact deflection. Could you tell me what program you've used to model your vehicles and mechs?
