Yes and no, OKW direly needs at least a one time AT weapon to fend of vehicles then.
As in the current state puppchen is not an alternative.
Please care. USF does get the AV grenade at Vet1. Yet OH and OKW get vehicles out much later than the SOV clownscar or the WC51. A Panzerfaust will not make them obsolete but make the opponent have to use that vehicle a lot more carefully as of current
What about Kubelwagen?
I agree with you only if:
- early USF "Panzerfaust" isn't be locked behind doctrine
- early soviet "Panzerfaust" won't require resource investment in teching
- USF/soviet AT guns isn't locked behind one of teching options (kinda hard to deal with Flak HT and fast Luchs without it)
