How do subs work?

I don’t think you can opt to ignore one unit and attack the other. It’s either attack all or none.

Attacking and defending subs can submerge before any dice are rolled, provided there are no destroyers present.

The UK sub has a chance of hitting provided he didn’t chose to submerge earlier plus the Japanese sub has to miss her first strike roll as well.

But seems you can ignore the subs if
you make a anphibious assault. I’m wondering if that also apply to this. Of course, it would be pretty strange but …

I liked more the old naval rules of Revised. This new are so confusing  :?

Sure you can ignore the sub that ain’t the issue, but ignoring the sub the AND attacking the transport is different.

Personally I think the new navy rules add a bit more flavour to the sea battles which were pretty much totally absent in AAR.  :wink:

Driel310 is correct.  Ignoring subs and/or transports is an all-or-nothing choice.  You can’t ignore one and attack the other.  In your example, as long as the UK sub survives and doesn’t submerge, the transport is safe.

OK. And the UK sub can submerge before anyone attacks, true? After all, it defends at 1s. Also, defending subs attack at the same time that attacking subs, true?

Yes, that’s true, but if the defending sub submerges the transport is toast.

Does that mean the attacking sub doesn’t have the first strike capability when attacking defending subs?

Attacking and defending subs may always submerge before any dice are rolled in a combat round, unless there is an opposing destroyer.

Yes, I understand that, but when the defending sub decides to stay and fight, the attacking sub rolls her dice. If it is a 1 or a 2, does the defending sub get a chance to fire back or is it destroyed because of the first strike?

Surprise Strikes are simultaneous.  If a defending sub is chosen as a casualty, it still gets to fire (assuming it’s eligible for a Surprise Strike).

Ok thx for that big K.

I recall this being different in AAR, it happened a lot with the UK sub attacking the Japanese one in the Pacific on UK1.

Why wouldn’t the other sub be eligibile for Surprise Attack too?

It would be ineligible only if there were an opposing destroyer.  There isn’t one in the example, but I was covering all the bases.

Krieghund you earlier said:

But the rules contradict that. It says specifically on p 30 that:
  “If both players have submarines, all the submarines get to fire a surprise strike before taking any casualties.”

I interpret that to mean that all the subs involved can not submerge but have to engage in the Surprise Strike.

Furthermore,  if Surprise Strike is defined as an attack, as it is on p30, then how can defending subs engage in a Surprise Strike?

If a cruiser moves into a seazone where there is a sub, how can the sub conduct a Surprise Strike, an attack, on the Cruiser when it is the defending sub?

Furthermore, if a legitimately attacking sub uses Surprise Strike against a cruiser it encounters, and chooses not to submerge, it can use it again against the cruiser?

Finally, if there is a DD in the sea zone, the Sub has to stay all combat rounds and can not submerge, and has no Surprise Strike ability; whether it is defending or attacking, that’s the bottom line?

Krieghund you earlier posted:

The sequence is:

1. Attacking subs submerge (or not)
2. Defending subs submerge (or not)
3. Unsubmerged attacking subs fire
4. Unsubmerged defending subs fire
5. Casualties are removed
6. Attacking non-sub units fire
7. Defending non-sub units fire
8. Casualties are removed.

Where is the Surprise Strike option?

The rules also say that “Anytime a sub would otherwise roll the die to attack or defend, it can submerge instead.”  The sentence you quote simply means that defending subs roll for Surprise Strike before casualties from the attacker’s Surprise Strike are removed, so they still fire even if they are casualties.

“Attack” was a poor choice of words.  “Fire” would have been better.  The rules clearly indicate that defending subs also get a Surprise Strike in that same paragraph.

@Constantinople:

Yes.  Surprise Strikes happen in every combat round.

Correct.  However, if the destroyer is sunk, the sub gains the ability to Surprise Strike or Submerge in the following combat round.

Steps 3 and 4.

I appreciate your responses and your patience.

I’ve got a 6 player game coming up on Black Friday and I want to be able to answer all the questions correctly and w/o frustration and w/o the flipping of pages.

So again my thanks for being “the answer guy.”

OK, I’ve re read all of the above and I hope I’ve got it:

all without a DD present:

If a UK sub enters a seazone containing a German sub, it can totally ignore the German sub, correct, regardless of the German sub being submerged or not submerged?  If UK ignores that German sub, then that turn is over and the German sub can not react, correct?  The UK sub can either submerge or non-submerge as it ignores the German sub?

If a UK sub enters a seazone containing a German sub, either submerged or non submerged, and it decides to Surprise Strike the German sub, then both subs get the Surprise Strike ability, correct? They execute it simultaneously?  Then if both survive, and if either one decides to continue with Surprise Strike it negates the ability of the other to submerge and save itself and they both continue simultaneously again?

@Constantinople:

dont think thats true because submerging happens before anyone can fire…

The sequence is:

1. Attacking subs submerge (or not)
2. Defending subs submerge (or not)
3. Unsubmerged attacking subs fire
4. Unsubmerged defending subs fire
5. Casualties are removed
6. Attacking non-sub units fire
7. Defending non-sub units fire
8. Casualties are removed.

i think the main thing that changed since revised (ok… lets say since LHTR), is that the attacker can chose to ignore subs, if they are alone in a seazone or only accompanied by transports.
apart from that, we have:
-) air units can only fire upon subs if they attack/defend together with a DD
-) subs can never hit air units.
-) also keep in mind that only DDs prevent subs from submerging and surprise striking. and also in combat rounds 2+, a DD needs to be present, if you want to cancel the enemy subs ability to submerge and surprise strike!
-) subs can move through hostile territories also during combat movement, if no enemy dd is in the zone that its moving through.
