| Notes | The Grille sIG33 Ausf M was another conversion that mounted a 150mm sIG33 on a Czech tank. Like the sIG33 Ausf H (Grille) the chassis was used on late models of the Marder tank destroyer in which the engine was situated in the rear which meant that the fighting compartment was mounted further back than the previous model of Grille. The sIG33 Ausf M saw service in Italy, Russia and France. |
