From the release:
Add mobile firepower to your German army with a 2cm flak gun mounted on a sturdy Horch heavy field car.
This re-working of our open-topped Horch model, by Darek Wyrozebski, adds the AA gun onto the back of the vehicle (taking up the passenger space). In your Bolt Action battles, it will allow you to quickly reposition the gun in the face of battlefield conditions, reacting to enemy threats as well as moving to the best vantage points. And remember, it will be highly effective against lightly armoured vehicles as well as aircraft!
