How does a tank, in this universe, get immobilized? Since the entire point of immobilizing a tank is to pierce its armour and damage the crew or some module of the tank. But if you put impenetrable carbon waxing on it, doesn't that make a tank invincible? I mention this as part of a specific scene in Das Finale episode 2, where BC Academy is up against Ooarai, the Porsche Tiger knocks an ALR 44 out by hitting its turret. If you see the scene, the area of impact wouldn't cause the tank to stop functioning. Perhaps I think too much, but this is the type of anime that gets you thinking.
Please give me a reply about your thoughts on the matter.
