Please check attached screenshots (its in spanish but is easy to compare in english), one for Pz V/IV and the other for Pz III/IV, both use the same gun 7.5mm kwk 40 L/48 and for the premium tank Pz V/IV (I just bought it ) the penetration is only 20 ?! against 38 in the normal Pz II/IV?
is it a bug or its the real value for the premium tank?
