Not to hijack this away from field ack but have you guys manned the 5 inch guns yet since the patch? They are absolutely deadly. One ping under 2K is not a kill, but a vaporization.
37mm field guns are good... 5" naval guns are LEATHAL! It now takes a coordinated effort to sink a task group. I think it adds more realism to the game when the ack can actually kill you, unlike the psudo-ack in days past. The best way to stop a vulch (i.e. break up a CAP) is to man the soft guns, up as many osties and werblewinds as you have defenders... and alakazamm CAP lost! It is easy to kill soft guns... as long as they aren't manned! A word of caution... bring lost of cheeze for all the whines you'll get on 200 after the vulchers "fun" is over!
