Just two main points, really:
- Change out the Karabiner 98 for a Pre-War Karabiner to match the scoped version or vice versa, as it doesn’t really make much sense to have one but not the other for scoped/unscoped - better if they’re both the same variant.
- Change out the German Axis infantry units to have proper desert-suitable cosmetics - minor change admittedly, but one that certainly helps with immersion and gives people more of a reason to pull up German squads.
That’s all I can think of to change for them - put your own down below if you have any ideas.
