They get slightly different veterancy bonuses, when compared with normal Ostheer infantry:
- at vet2 they get x2 bonus armour (vs x2.25 for most of German infantry)
- at vet3 they get x2 bonus damage (vs x1.78 bonus accuracy for most of German infantry)
Those changes make them somewhat more offensive oriented, which I guess, fits their theme.
But I wonder - why was it done like that, especially when all the other veterancy bonuses are basically the same for all the units of the same type/side?
