A year agoc panzerfusiliers were changed allowing them to be an alternative Volks, but I find unit to be lackluster they are near useless without their expensive g43s upgrade, and by comparison Volks are more reliable and cost effective core infantry. Another problem with PFs is the Panzerschrecks upgrade it gives OKW access to a fairly cheap AT blobs that if used correctly can be a nightmare for Allied tanks.
here are my solutions to both problems.
