I’m really hoping for early war, especially France 1940 and the Balkans campaign up to the fall of Crete in ‘41. Various Cruiser marks and Matildas for the Brits; Char B’s, Somua’s, Renaults etc for the French; Pz Mk l, II, 35t’s for the Germans. No big HE chuckers, so that ATG’s have a fighting chance.
But if that’s too ambitious, I’d happily accept the Western Desert campaigns over the same period.
