I think its pretty much a toss-up. If you attack Ukraine the drawback is that German forces there are slightly stronger (by 1 ARM), but you can put in more forces there, and when you win, its harder for Germany to counterattack next round–plus you take out an extra tank…
If you take Eastern Europe, you can’t put in as many forces, but the Germans there are slightly weaker. One bonus to this move is that you block the Germans from putting 4 ARM into Karelia next round (in Germany, Southern Europe and Eastern Europe)! However it leaves your ARM in a highly exposed position where the Germans will be HIGHLY motivated to take you out…
On second thought, maybe Ukraine IS the way to go after all…up to you…
Just my thoughts…
