Sherman's merits are not to be highlighted in AH, such as reliability, flexibility, better track range, and not as loud (rubber belts)
....at least not soon.
The Sherman was OK vs the lighter Panzies in the desert, however dreadfully weak (Armour, profile &gun) in the beginning vs the Heavy German Tanks in Northern France.
I do recall some mods of the Sherman with a lengthened tower (I think) and a high velocity gun that equalled everything there was about in the armour piercing business. Maybe AH will feature an early and late Sherman?
Anyway, there were early and late T-34's as well, and some late ones also carried machine guns.
The Brits received some T34's from the Russians, and promptly declared that there was no finer tanks.
Bear in mind the Speed, 10 mph between aircraft already makes some difference, 10 mph between tanks makes a LOT.
