well mav, you can deack it on your own because it wont hit a 200mph turning plane unless that plane flies RIGHT over an ack gun.
The 37mm refire rate low.. there are QUAD 20mm's there as well.
IMO, there should just be a LOT of single 50 cal and quad 303's AI acks. More guns means more things a single fighter has to shoot out, means more guns shooting at different targets with a very increased rate of fire.
In short, it could be like fleet ack..only with a higher refire rate.
