I aways Make sure that i have a qualified officer in the watch tower that helps, plus make sure you have atleast one guy qualified to man the AA...make sure they are on fire at will, and check the settings of the AA ( engage all targets/ maximum range )last but not least always make sure the AA is in the starting position Eg facing the aft of the boat, I have noticed if the guns are facing anywere other than aft they WILL NOT engage.
