A prime example is provided by French dragoons. They are marked as ‘heavy’ units in BGW and PtW – but the same dragoons are not marked with an “H” in NiR. See the attached image: a BGW dragoon is shown on the left whilst a NiR dragoon is on the right.
There are several other heavy cavalry units in the BG games that do not have a “H” icon.
P.S. I think the unit graphics in the BG games are great.
