Wirbel Dirbel Flakpanzer IV Wirbelwind: The Wirbelwind was a SPAA (Self Propelled Anti Aircraft) that was given the hull of the Panzer IV. It had quad 20mm cannons stuffed into a misshapen "decagon" turret. Only a few other vehicles gained this type of turret, those being the Ostwind and Ostwind II (the electric boogaloo). The Wirbelwind wasn't a very common to see. Only 87-105 were ever built
