Idk what game you are playing, but volks cost 250 mp and reinforce for 25 mp a soldier from what i know.
Meanwhile, Rifles cost 280 mp to buy and 28 to reinforce 1 man.
Penals are 300 mp and 25 mp or so to reinforce? idk the latter for sure.
If Penals and Riflemen are less expensive while being reasonably superior to volksgrenadiers in most aspects, OKW would be dead earlygame.
(Why do volk reinforce slower when they have vet? since when is this a thing?)
On a sidenote: you lost a panther to PTRS(or someone else)? That's impressive in a bad way. Not that i wish to imply that it is impossible, but oh well.
I am sure that volk reinforce slower once veted up,i can feel it but then again could be wrong.Hmm why did i think Allies infantry is cheaper(before checking the stats)?maybe had something to do with how often blobed up they are.
As for the PTRS killing Panther thing,i just saw it recently,quite shocking to be honest

So this is my conclusion with this thread
1)Give ober doubled shreck.Do it like US Captain?or panzergrenadier.Or they could create a commander that Specialize on countering enemy armor?
2)Early rakenwefer is enough i think,mid to late game you will had your panzer command set up so getting ober for those tank seem natural
3)If don't want to rely on infantry cause they could got wipe by blob then just use Jadtiger for the Heavys.
