- It's difficult to kill Infantry Section models; each one has a lot of hp, and models seem to survive until VERY low levels of squad health, so they can retreat with 3 or 4 man squads with very low health.
Each entity has 80 health like others in the game. It's mainly their target size of 0.8 (1 or close to it, is the norm for vet 0) and the cover bonus combined with volks accuracy that makes them durable. Forcing them to move out of cover for example with a sturmpio will help a lot because tommy's have really bad moving accuracy.
- There's no weapons upgrades for volks, so it never really gets easier to vet down the line, while brit lmgs wreck volks
Volks main source of vet in any other matchup is vehicle damage in most cases. As you identify correctly, there isn't much vehicle play to be expected from UKF until later.
ISGs work well against UKF
In cover about as strong as grenadiers, out of cover about as strong as osttruppen.(no exaggeration here).
According to Cruzzi, the cover bonus rate of fire is 20%. I'd expect them to still clearly outperform osttruppen out of cover. Moving accuracy is however amongst the worse for any unit at 0.25.
