this is the Panzer 38t 2cm
the wirbelwind
the Moebelwagen
the 2cm flack 30 Sd.Kfz.10/4
and the 3.7cm Flack 36 on a Sd.Kfz.7/2
these were also used with Quad 2cm guns and the 3.7cm gun as used in the ostwind and moebelwagen
no ones sure if the Ostwind was used in the Ardennes or not but there are so few photos of the Ostwind atal
the photos that are known are of the prototype Ostwind and the Turret was changed on the production turret
