Nope, I waa saying that the code for multicrew exist. There's already 2 3rd parties doing it, it's enough.
But conserning the door gunner, I wonder how hard it'll be to it infantry. I mean, with the A-10 you're coming straight at them and if the bullet is 2' off you won't hit.... Now imagine doing the same thing but with a smaller calliber AND going sideways...
