Or up in a GV, or hop in the field ack.
Personally, I prefer the M-16 as I find the quad .50s much easier to land hits with (then again, I'm more accustomed to the ballistics of the Brownings vs cannon) and they can be real messy. As long as you get guns on the target it's fairly easy to discourage someone from strafing you. Bombs and rockets you need to worry about, but so does an Ostwind.
I quite like the quad 40mm of the CVs, though.
