Hard to say. 2 junior but equal players might always end up with an allied victory. 2 medium but equal players might end up with an axis win most of the time. 2 experts and equal end up with allied victories.
3rd edition helps allies more then axis IMHO.
RR and German rockets alone might be enough, if not give germany jet power (ftrs defend on a 5). Somebody at our group coined the term piranha for a German jet fighter. Couple of those in a stack of infantry adds some back bone! No rolling 4 times each always missing, they always take a bite!
