Taamvan,
No Russian player has ever asked me if his sub could exit the Baltic…but if asked, I probably would say no…I think I was just venting after the table top game where the guy rolled a 1 and killed my destroyer. Â The game where my fleet was outside the Baltic, I was going for a defensive fleet that had enough meat to project a threat. But that one Russian sub really snubbed the buildup of the fleet. I don’t want extra Russian subs out convoying Germany or going into the Med to convoy Italy.
But sometimes I play with just enough boats in the Baltic + a scramble to protect enough transports to kill a Norway invasion as all other IPCs are invested in ground for defense, mobile for the march into Russia, and air for whatever purpose. After that roll of a 1, I could see the Russian sub doing that to me followed by an Allied Strategic Bombing attack to finish off a small Baltic fleet which could overcome a German scramble.
I may have misunderstood another aspect of your message response, so please don’t take my response wrong.
Did you mean that the Russian Cruiser and sub could theoretically be in SZ113 while Germany and Russia were at peace to prevent Germany from loading transports in SZ113 when wanting to declare war on Russia? Or did you mean just the Russian sub in SZ113?
The Russian sub doesn’t prevent the loading of transports of course (page 13 of the Europe rule book).
