No more Eastern Front thank you very much. It's too boring and isn't nearly as exciting compared to other theatres of war where the British Army despite being outnumbered, defeated heavily armoured and experienced German divisions in Africa, Europe and Asia. Also, the Romanians, Slovenians, Italians and etc are finely represented by the Ostruppen unit, so there's no need to introduce Romanian commanders and etc.
My answer is the British Army(Which includes Canadian infantry as a stock unit or as a commander) and the German Afrika corps.
But what you're saying, it took three years to oust the axis army from Africa ( and the Americans have helped a lotif not, it took months before others to drive them from the mountains of Tunisia) ,
also having more men,supplies and means , and the commander montgomery was overvalued lot.
why add only the Afrika korps? the Afrika Korps is only German troops and you can not have three factions German, if you meant Italian and German units with the right name is Panzerarmee Afrika (end campaign africa)
