ok how about Vehicle/boat rank only.
A good gunner is what is needed to save a ship or carry out the necessary shelling.
The rank boot option is already in place for overall command why not for a lowly gun position?
If you can see who is in the gun I would only use it to kick "newer" players out only and even then when it matters.
Of course even experienced players may not be that good when it comes to naval warfare but it would provide an incentive to stay alive and improve score.
