If we presume that the Germans were more successful in the Caucasus in WW2 how would the British 10th Army fare against them? Would logistics cripple them or would they be a serious threat to British dominance of the Middle East.
Not so much direct damage, but causing the Brits to commit resources to building 10th Army from a occupation force to a field army. The 10th Army was more of a skeleton without much muscle.
