Oh, OK, my mistake about the sea zone number – but if you’re going inside the Mediterranean, then how does the British navy prevent a German Sea Lion attack? Seems like there’s all kinds of possibilities for Italy to attack it (even if Italy doesn’t win, the British navy might be crippled), or for Germany to seal it in with a non-combat move into SZ 93…I’d be really nervous to build only 1 inf, 1 ftr in London, fly fighters to Gibraltar, and then sail the navy south. What’s left protecting London, exactly? I’m not 100% sure how I would stop the British Med navy from returning to defend London, but there’s got to be some way to do that.
I’m also really skeptical about this claim that you’re trading the British Med navy for “the rest of” the German air force. If you’re not scrambling, German air casualties should be very light – 1 or 2 planes even on a bad day.
