Rule question - sub damage

@chernobylime Good morning. Once the Sub has had its SUrprise Attack, all surviving enemy naval units can fire back. Air unite can only fire back, if a friendly DD is present.
I hope that clears it up for you. Enjoy your games.

Appreciate all the help. Lots of great explanations and clarifications of the rules.

@ColonelCarter:

(…)
Point (3) only says that the dice must be rolled simultaneously (i.e. before any casualties are chosen), it does not say that you don’t have to keep track of what unit rolled what. (…)

Thanks, Colonel, that cleared it to me. I can sleep well again, knowing I always played it right ;-).

Welcome, General A-Ron!

Wheatbeer is correct.  Since Kamikaze strikes occur at the beginning of the Conduct Combat phase, any attacking air units are already in the air.

On the subject of convoy disruption, here’s a quote from the 2nd edition Rulebook:

There are three conditions that must exist for this kind of attack to occur:
1. The sea zone must have a “Convoy” image,
2. The sea zone must be adjacent to one or more of your controlled territories, and
3. At least 1 warship belonging to a power with which you are at war must be in the sea zone. (Any ships in the sea zone that belong to you or a friendly power will have no effect on convoy disruption.)

Convoy attacks on “Convoy” sea zones are conducted in the following manner.

Each enemy warship (except for aircraft carriers) and carrier-based air unit in the sea zone might cause the loss of 1 or more IPCs from your income for the turn. The owners of enemy battleships, cruisers, and/or destroyers rolls one die for each such unit, and the owners of enemy submarines and/or air units roll two dice for each such unit. Any rolls of “4” or higher are ignored. The results of these rolls that are “3” or less are totaled, and the resulting number is the total convoy damage suffered in the disruption. However, this number might be limited. Each disrupted convoy can’t lose more IPCs than the total IPC value of your controlled territories adjacent to the sea zone. Also, no single territory can lose more IPCs than its own IPC value from multiple disrupted adjacent convoys (for example, Japan cannot lose more than 8 IPCs from disrupted convoys in sea zones 6 and 19). After these limits are applied, the final total is subtracted from your income for the turn.

@SunTzu7:

Just wanted to check a sub rule. If a sub goes up against other non transport, non destroyer type ships (in this instance a damaged carrier and cruiser), can the sub keep doing a surprise attack till the opposition are destroyed without them firing back? That’s how my friend read the rules.

Like Brado explained, yes the sub gets a “surprise strike” each round.  But the defending carrier and cruiser do fire back every round provided it was not sunk by the sub surprise strike.

So in your example, if the sub hit, the defender would choose a casualty.  Whatever he chooses will not roll (will not fire back) but the other unit will fire back.
Subs get surprise strikes at the beginning of every single round of combat (the first round AFTER the last enemy destroyer is sunk), even when they are on defense.

If you read through Step 2 under General combat (Submarine Surprise Strike or Submerge), the rule book tells exactly how to handle sub combat and makes it very clear that surprise strike happens every round, and also how to handle surprise strike casualties.
One such sentence:
“As long as there are attacking and/or defending submarines and no opposing destroyers, this step is repeated during each round of combat.”

Just as a side note Make_It_Round, in alpha if you had a Japanese sub in the sz he couldn’t do an amphib w/transports only. This would force him to bring in surface ship(s) to escort the transports. Then you could use your sub & kami’s to try and sink his surface ship(s) if he still does the amphib. You probably only have a destroyer as a target, but hey makes him think.

Yeah.  The fighters can scramble to defend, but without a destroyer present they can’t target the sub.

Lucky indeed….thats is why I have never had this question before…sub always dies…
