I can understand the BP in close quarters maps but why the Sherman? wouldnt P26,Pz3/4, stugs, Semovetos and AT guns be able to deal with them?
P26 wasn't a thing in Africa. Most other "powerfull" Italian Self Propelled guns also weren't around in Africa and were pretty much only used by Germans. The Semovente 75/18 which was around in Africa only has 50mm of armor while it apparently only could penetrate 80mm of armor. No match for a Sherman. The Italians apparently also had Semovente da 90/53s in Africa though. Those could penetrate more armor but they only had 30mm of armor themselfs.
Panzer 3/4 were German tanks but idk maybe Italians used some of them.
Afaik their only reliable AT guns were AA guns that were used against Tanks too. Those things would be easy targets for mortars or rocket arty in game
So pretty much Italians would have to get a slow, turretless TD to even be able to deal with non-doc Mediums. As soon as something like the BP enters the scene they would have a hard time
