I would argue that the italians would just be ostruppen plus german equipment. I'm not arguing that the italians didn't contribute to the war, I'm saying they might be redundant.
nah on tank we had almost only light tank most of the medium and heavy where from german but we had varied elite inf and some nice light tank
the faction could work like panzer elite with panther call in 1 time and focus on light vehivcle put a command "carro armato" like the command p4but differnt buff and we have an unique early game faction
