Dogfighting: Gunner or Vehicle Skill?

[weby]

You fire with gunner skill.

In 4th edition there is no limit based on the vehicle skill. In Third edition the Gunner skill of weapons like on a WWII fighter plane were limited to a max of pilot -3 and it caused "interesting" effects where a single rear MG was way more powerful in effect than all the forward firing guns as the rear gunner had an effective +3 to hit.

That being said: I highly recommend using dog fight rules for combat where the weapons are like that, the requirement to win the quick contest of the chase to be able to fire then uses the vehicle skill for the "allow firing" part.
