Shouldn’t “fighter” be replaced with “cruiser” in the first line of the answer. The defender has a sub and cruiser, the attacker has the fighter.
Q. Assume there’s a sea zone that contains an enemy sub and cruiser, and that I attack it with a destroyer and a fighter. If the defender scores two hits in the first combat round, can I take the hit from the cruiser on my destroyer, saving my fighter, since the sub can’t hit it?
A. No. Because you have a destroyer, the defender’s sub rolls in Step 4 along with his or herfightercruiser. Since both defending units roll in the same combat step and all dice are rolled in a step before applying casualties, the two hits are applied together. Therefore, you must apply both hits if possible. The only way to apply both hits is to take the cruiser hit on the fighter and the sub hit on the destroyer.
