Yes you are correct, NOs and standard dice Subotai but I will disagree with 41 needing a bid. So far stats have shown it to be balanced. As far as 42 I have not formed an opinion yet but I am leaning towards it needing a bid or Dardanelles closed perhaps.
As far as the lifespan of the German Navy that depends. If the Allies go all out perhaps as early as turn 5, but I feel this will leave the Allies in horrible shape globally. Africa will be Italian or Japanese, Japan will be either coming hard after Russia or attacking the US. Keep in mind that this fleet is allowing Germany to put some heavy ground pressure on Russia in the form of troops being landed from Germany to Karelia every turn, in addition to what is built there. While the southern Eastern Front may get thin, Russia can not take advantage of this as it is having to defend against Germany in the north. Also even if the Allies eliminate this fleet in say turn 5, Japan has had the time it needs to start pressuring Russia and Germany can switch from offense to defense.
Keep in mind as well that Germany is adding to this fleet every turn until it is obviously out gunned by the Allies. At 50 IPCs Germany can dump 30 or so IPCs a turn if they feel like it and still out produce Russia in land units. Naturally when it appears the fleet will no longer be able to be maintained it is time to retreat all aircraft from it so they are not sacrificed.
The German fleet does many things that need to be considered.
1. Allows immediate movement of infantry from Germany to Karelia for trading or capture and hold.
2. Keeps Norway and Finland secure.
3. Threatens England and forces them to defend England instead of contesting Africa.
4. Forces the Allies (US and UK) to respond to its presence.
5. By quickly placing troops on Moscow’s doorstep it allows Japan time to get mobilized at which time Germany can go defensive if need be.
6. Protects the Italian fleet.
I am not saying that this is the ultimate sure to win every game in 42 strategy. It is however a strategy that can put the Allies in what so far looks to me to be a very bad situation.
