I asked it on the paradox forum, they send me directly here, so:
a few unit name changes.
There are:
Austrtian Uhlans, and Austrian Hussars, right?
Also Hungarian grenadiers, and Hungarian line infantry.
Fisrt of all:
Uhlans-> Polish people were so good lancers, Austrians recruited them as Uhlans
Hussars-> Austrian Hussars were the late Vitéz society (Hungarian calvary), it was very rare that non-Hungarians were accepted as a Hussar.
I suggest to change it:
Austrian Line infantry (Hungarian)
Austrian grenadiers
or:
Polish Uhlans
Hungarian Hussars.
Oh and the nationality of Austrian Cavlary: napoleonistyka.atspace.com/Austrian_cavalry.htm#
Just a suggestion.
