Real life M47 is not Big Boss's M47. It's an entirely different weapon (for one, Big Boss's requires no manual guiding. For a second, it's way the hell stronger. You are conveniently ignoring the fact that the M47 in Peace Walker easily smashes up *every other* part of the mechs, too, not just the AI pods. Shoot it at the treads, mech will lose its treads. Shoot it at the body, including stuff that is literally built to be heavily armored, like Cocoon. Body will go boom. The M47 is just overpowered as hell. Period. Full stop)
And as for Paul, he punches Bryan around during the Tekken 6 intro. Helicopter thing is during Bryan's ending, and Tekken endings are always of dubious canon. The intro holds more water than Bryan's ending
