'Obersoldaten' is kind of made up term to me. I noticed that they are SS, and SS ranks have a lot of 'Ober', 'Sturm' and 'unter' prefixes. The 'Sturm officer' appears to be SS as well (if my pictures are correct).
The 'Panzerfusilier' is very niche- There was a regiment of the GD division called this but it was just a name designed to ease identification. 'Fusilier' battalions were late war German light infantry battalions that replaced the traditional recon battalions int the infantry divisions. It's kind of a meaningless name as well.
What does have meaning, however, is Jaeger from Ostheer. 'Jaeger light infantry' is used, but in a weird way.
Historically, Jaeger divisions in 41-42 were elite light infantry divisions with different equipment than a line infantry division. They were usually in reserve for offensive action.

It's not manpower starved, too? I did, in a very rough manner, observe the fuel progression. It looks to me that they get maybe 75% of the fuel that the other factions do.
So there's the Jagdpanzer IV left, and it's probably in one of the buildings that we didn't see.
It's funny because normally a Super Panther call in would be great for Ostheer but for this faction..heavy duty AFV is the norm.
The 3rd commander ability appears also on top of the profile for the 'Obersoldaten'. It is a muni purchase that gives the units STG44s with infrared scopes. Does it shoot through cover? Range bonus? It's not nighttime..
The 5th commander ability is command panther. He explained what it does in the video but I didn't catch the details.
