On a related note: Why isn´t it possible for German infantry to fire from the 251 - like the Soviets can from their clown car? After all it was the Germans who invented and massively the concept of mechanized infantry firing from halftracks. Russians were more relying on tanks to move their mechanized infantry. Hell, for balance they could lock Schrecks from going into the 251. Is it possible for the Russians to fire from their halftrack?
Yes, Russians can shoot out of their M5.
