in my fictional Call of Duty Game named "Raging War", this are used all over the world, we have Future Weapons, like this giant tank i call a M15 Nuclear Tank, it is 500 Feet long, we even have some weapons that are from Black Ops 2(Coming This November). The year is 2056, so it is 20 Years too early for this, lets hope the War Tank i designed makes it through testing.
