I'll have to read the rules again when I get home. I don't think the panzerfaust stays on the board - it's just a random event thing that either does something to your tank or doesn't. Basically in game terms, any of the German infantry units could be carrying panzerfausts but they are only in use during the random event at the end of the turn sequence.
Note these are single use weapons, not reloadable like a Bazooka or P.I.A.T. !
[ Panzershrecks are reloadable , but the game does not have any of these !! ]
