I'm going to just reply to this so the context is kept rather than explain it all in a ticket.
The Tank Battles Austria scenarios were already using the substitute counters in the library (displaying Shutzbund and Heimwehr in their own colors as were finally printed in Hopeless but Not Serious, so there isnt really any updates needed for that specifically.
I would suggest adding to the notes for Scenarios 7 & 8 (Austria Scenarios 1 & 2) that the Heimwehr were originally using the Luftwaffe units from HoSU/RW. We already have a note reflecting the use of RKKA units for the Shutzbund in Scenario 7 (Austria 1). The RKKA note does say EFD, whereas it really should be the East Front (the original), but thats beside the point.
There is one orphan leader situation though, where the Shutzbund calls for 1 x KOM (Sc 7, A.S.1). There were no Kommissars in the Shutzbund colors for HBNS, and currently this KOM is not in the scenario entry in the library. I'll leave this one up to the sensibilities of the Librarians, but it seems we can either:
1) Add 1x RKKA KOM to the OOB in the scenario library entry
2) Create a dummy KOM unit in the Shutzbund colors to add to the scenario library entry
3) Add (another) note to the scenario adding the KOM there
4) Do nothing and say close enough
