So far as I know, armour thickness and armour sloping were optimized against enemies on the ground (enemy tanks and artillery), and tanks were quite vulnerable to aerial attacks. That is, a 3.7 hit from above could do as much damage as a 7.5 hit from the ground. Dunno what consequencies it had, but SOME consequencies it must have had.
