Ostwind German Anti Air

The Flakpanzer IV "Ostwind" (East Wind in English) was a German self-propelled anti-aircraft gun based on the Panzer IV tank. It was developed in 1944 as a successor to the earlier Flakpanzer IV/2 cm Vierling Wirbelwind.The Panzer IV's turret was removed and replaced with an open-top, hexagonal turret that housed a 3.7 cm Flak 43. In addition to its intended role as an anti-aircraft weapon, the fast-firing gun was highly effective against light vehicles and minor fortifications. A closed-top design would have been preferable, but this was not possible due to the heavy smoke generated by the gun.
