Well with Russia unrestricted, I can definitely expect Ukraine to be taken. Of course even with Russia restricted, I can still expect a strong presence on part of the Russians in the Caucasus. And as a rule I will generally not invade the Caucasus on part of the German Army due to the fact that the Russian counterattack can wipe whatever fighting force remains (and usually a good deal of ARM unless my Luftwaffe is free).
As for Africa, it is crucial to the success of Germany and the Axis to take it. 2 infantry per turn does seem like a lot, but the 8 IPC return investment is just too great. And with USA due to arrive in Africa very soon, I need whatever I can to slow down their reconquest. Victory for Germany is based on these priorities:
Protecting Eastern Europe at all cost The continued occupation of Africa The protection of Western Europe at all cost The protection of the Luftwaffe and the Panzers5. The protection of the Mediterranean fleet
