I apologise if it's already been mentioned, but model names are a bit screwy. In particular, aircraft model names are non-existent, but land brigades are messed up in some quite exciting ways too. For instance:
Tanks are currently only upgrading one model name every full tech level upgrade, instead of progressive design, where you'd expect to see a prototype Panzer III (Ausf. A-D) upgrade to a Panzer IIIF with improved reliability, and the onto IIIG with a gun upgrade, and the Ausf J with an armour boost. Using indicative scores for Gun/Armour/Engine/Reliability, what you'd expect to see is e.g.
2/2/2/2 - some manner of prototype, e.g. Bataillonfuhrerwagen
2/2/3/2 - Panzer III Ausf A
2/2/3/3 - Panzer III Ausf F
3/2/3/3 - Panzer III Ausf G
3/3/3/3 - Panzer III Ausf J
Instead you get:
2/2/2/2 - Bataillionfuhrerwagen
3/3/3/3 - Panzer III Ausf A
4/4/4/4 - Panzer III Ausf F
Etc.
There's also the issue with Artillery and AT brigades having specific names, e.g. 3.7cm PaK 36, yet having a 5cm PaK 38 as one of its technology components. Would it be possible to conduct a scrub of the brigade names and tech names to ensure these are aligned?
Edit: actually, it looks like that might already be in the patch change notes. If so, sorry.
