They had several stug batteries which instead of the normal SzuGIII - StuH42 mix had the Marder I (the kind we have on Goodwood), either with 7.5cm or 10.5cm guns. Instead of normal Sdkfz251 hanomags they had French models, some of them mounted with 3.7cm guns, or in the tank hunter units with 7.5cm Pak40s.
Besides the Vielfachwerfer already shown they also had a so called "Reihenwerfer", which basically consisted of several 8cm Mortars mounted on the same vehicle and synchronised.
