@nishav Agreed. But what I find interesting, is that if the assault goes down, the ftrs can scramble, but can the attacker choose to ignore the subs? i.e., they will only have a naval battle against the ftrs, and assuming they win, then the assault occurs. All the while, the subs are impotent to stop anything.
Or because there is a naval battle, does the defender get the option for the subs get to engage, which might change the attackers strategy since there are a few extra hits to account for?
Obviously, if there is no DD in the attackers forces, the sub can just submerge, but I believe the important part of this question is to know if the subs get to fight.
