Ask SUD or Bossk. They’re practically walking rulebooks.
Defending submarines against air attack
Suppose I have a have a force of 1BB, 1DD and 3 subs, being attacked by 3 fighters.
I think the subs can’t defend, but can you use them as losses?
The subs aren’t valid either way. Without a Destroyer in the seazone the FTRs cannot attack the sub so it is FTRs on the surfaces ships only. Subs can’t shoot aircraft.
