The Wirbelwind is essentially a Panzer IV chassis, fitted with a Flak 38 rapid-firing quad 20mm Anti-Aircraft cannon. You may select a destination for this ability, in which case the new Wirbelwind will automatically travel there after entering the battlefield. Each use of the ability costs 480 480, 8 8, and will field a single Wirbelwind. This ability becomes available once the Wirbelwind Flak Panzer Command Upgrade has been purchased from the Luftwaffe Tactics Command Tree. The Wirbelwind Flakpanzer is called in from the field using a Command Ability also called Wirbelwind Flak Panzer. To remedy this, the Panzer Elite can instead field a mobile version of this gun, having many advantages that can be put to good use. While the Luftwaffe Tactics doctrine allows the Panzer Elite to construct anti-infantry emplacements in the form of the Flakvierling 38 20mm AA gun (its only active anti-infantry defense, in fact), this stands in contrast with the mobile offensive nature of this faction.
