Don't want to see faust added to Volks, makes them too much like all the other infantry.
Remove schreck, add 2x Panzerbusche, buff raketen. Keep the faction unique.
They are durable as rifles(not when vetted though, unless we talk ooc heal vs rec acc as both affect staying power).
They are packed with utility like cons(flame nades, possible doctrinal cancer nades, hard at, build sanbags).
They punch like grens(actually, they surpass grens unless grens go LMG).
They only lack cover acc bonus, other then that, they already have something from every other infantry squad, so they are pretty much like all the other infantry in one unit already.
And they definitely won't get weapon that wasn't used for years already.
