I just have a problem sinking a piece without even rolling a dice.
Same thing here.
You must rolling die to sink a warship escorted or not.
The only long range sortee by unescorted battleships that I have ever heard of are the German convoy raiders of WW II. I just feel that there should be some penalty for a player doing such a foolish thing in AA. Maybe a one shot attack and then submerge is enough.
Either subs attacking unescorted capitol warships get 1 roll, if a 1-2 ship sunk on 1st hit. if sub misses,sub is considered submerged,breaks off attack,but if it stays in sea zone to try again next turn or follows same shipsinto another sea zone to try again next turn, destroyer and cruisers detection roll is upped to 1-4 becouse sub is known to be activly prowling area.
Well if a player let his warship alone, it could be destroyed.
Sub must continue his attack after the first round of combat or warship alone can escape after the first round. - But I prefer the first option-.
