I think this is not really the tanks you see in Call of Duty and Leo did design a tank in real life, just as he had ideas for a flying machine, but like the tank it never sprung to life, unlike in the games. So what's the difference between the flying machine and the tank, cause both were designs that never were built, yet they are in AC. But I don't see anyone complaining about the flying machine, then why do they complain about the tank?
