NotesThe Wirbelwind (Whirlwind) was also built on the chassis of the Panzer Mk IV and these like the ones used to build the Möbelwagen, were initially sent back to be overhauled. It mounted a quad 20mm Flakvierling 38 which was housed in a nine sided turret which could fully revolve at 360°. The turret itself was open topped and thinly armored. It had a good rate of the fire and could also be used to engage ground targets. The Wirbelwind 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.
