OK so a lot of people are probably going to get mad at me for this because a lot of people use this. When ever you as a gunner get into a bomber gun you get full ammo , the pilot won't but the gunner will, so very time the hunter leaves the plane and comes back you get full ammo. So unlimited Ammo. I know it's great for defense but the attackers don't have that
.. just an interesting bug that has its good quality and bad ones
