@Gargantua:
Can you scramble to defend a transport even if it’s JUST attacked by a sub?
YES I am aware you cannot hit the sub.  But what if you scramble anyways, so that you move from the territory you are in, to a sea zone?
There is a reason for this.  Say for example a german sub attacks a Russian transport in Sz115.  1 fighter is in Leningrad, about to be blitzed by 8 tanks.   Can I scramble?  And then after said territory is lost?  Land in Vyborg or some other place?
Per the letter of the rules, yes.  Despite the fact that you couldn’t hit a sub in that instance, you can scramble against any battle (or possibility for a battle).
Obviously, regarding landing, your planes only have one move, so it’s either SZ114, vyborg, baltic states, finland, or a captured sweden.
