Any ship may engage ANY ONE ship within range. After this is resolved, the defending side may elect to disengage or close the range. If the action continues until the action is at secondary range, torpedos MAY be used after the gunnery round. Torpedo attacks are resolved the same as sub attacks, but there is NO ASW effect. Instead each attack roles against a to hit atble based on the targets protection factor.
All damage is cumulative, and is simultaneuosly awarded at the end of each round of shooting.
Air units return to base. Hope this was interesting.
