| Notes | The Ostwind (East Wind) was only produced in small numbers compared to the Möbelwagen and Wirbelwind. It too was built on the chassis of the Panzer Mk IV and many of these had been withdrawn for repair. It was armed with a single 37mm FlaK 43 mounted in a hexagon shaped turret that could traverse 360° and engage targets in the air and on the ground. It offered better armour protection for the crew then on previous models and the 37mm canon had a high ceiling then the 20mm. The Ostwind was used to provide anti-aircraft cover for armoured columns and located in anti-aircraft platoons issued tank regiments, it mainly saw service in Western Europe. |
