Question:
It seems to me that the intrinsic AA of ports cannot fire at air units bombing ships in the port (“all non naval unit AA in the hex”), but the port intrinsic AA may fire at air units bombing any airfields in the hex. Is this correct? Should there be any changes when dealing with Soviet River flotillas?
Answer:
Since the intrinsic AA is not generated by a naval unit, it may certainy fire against air units flying the naval units in port mission. The rules say that all non-naval unit AA may fire, as may the single naval unit with the greatest AA strength. Intrinsic AA is non-naval unit AA, as is the AA strength of any unit with AA or any static AA in the hex. River flotillas are “in general… treated as ground combat units”. So AA from river flotillas would also be considered as non-naval unit AA.
