1)We may use in a mode "not show units".
2) Sure, you have created them yourself, so you know, where they are.
3) I read "Stalins papers". I see diplo here is quiet weird: Japan declare to Russia, Tula was captured -- that was not historically true.
Also, Russia at that time had good chances to return Kharkov (Karkov on map), again no chances for that with that troops position.
OK, we play game, not a "history", but can be diplo really screwed, like early peace of Russia - Germany?
Or we play "without e-mail diplo"?
What about battle log? (I hate it).
I definitely will have more questions, but in first approximation "it is".
