I know what u are all going 2 say " the acks fine how it is" "its not to accurate, thats how accurate it was in WWII."
well, the ack in WWII was hand cranked and could not keep up will a plane flying at 400 mph through it, it was physically imposable for a hand cranked ack to turn at 400 mph, ack was only good at high alt and head on attacks.
