Vet 0 obers were always trash until they fought team weapons.
Obers start to shine from vet 2 where they get insane +40% accuracy bonus.
Wait...this is simply not true. At release vet 0 Obers were insane, they even had bonuses against retreating units.

Just based on this, volks, which we said had the worst vet 5 in OKW compared to their mainline allied infantry (for instance Sturmpios have so much deeper vet that they obviously beat all other engineer units), volks are still in line with all other Allied infantry at vet 2, do not get the received accuracy bonuses other units do ever, but to compensate get free healing whenever out of combat, and get far more bonuses related to their shooting of guns than other infantry. Ultimately, they get better at shooting, remain ok at avoiding incoming fire, and get no better with grenades (which as OKW has meant little since they have often avoided using munitions expenses, especially in the late game where tanks matter). On top of that they require 0 upgrades in fuel (unlike every other mainline infantry, arguably even Grens), they have the cheapest reinforce, lowest initial cost, and they vet quickest. I understand vet is being adjusted slightly, but seriously where is the vet 3 in 5 levels of vet, because here it looks like vet 3 in 3 levels, plus 2 more for extra fun, and this in the unit with some of the weaker vet in the OKW.
