I do not think there were any Italian colonial troops in Tunisia. All Lybian soldiers were discharged when the retreat arrived at the Lybia-Tunisia border.
I was referring mainly to the British colonial troops, such as the ANZAC and Indian forces that fought in the Desert campaign.
I agree with this post.
I will speak for the Italians as I don’t play allies in this campaign. Not a single german weapon doesn’t have an Italian equivalent. Not a one.
If they go to level 40 issues will be with MG Anti-tank units and tanks. So sure some high end German squads will be necessary. But they can definitely be all Italian now and for a while yet.
