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)
Montgomery was a much better General than Rommel as evident by the fact that he defeated Rommel and ended his precious Afrika campaign.
Why add only the Afrika corps? Because the Italians are represented by the Ostruppen unit for the Wehrmacht, and it suits them finely along with the Romanians and etc. Italy, Romania, Slovakia and etc had the worst troops in WW2 so it wouldn't make sense to add any units from those countries since they're already in-game via the Ostruppen unit; they were used in WW2 to soak up damage and were practically cannon fodder; the same function the Ostruppen serves.
Honestly, if Relic does decide to add any Hungarian, Romanian, Slovenian unit, i'm going to protest them and write a petition. The only units that should be in CoH2 are units that actually fought hard in WW2.
