PanzerJäger SK 120
Based on the Panzer SK VI Mammut chassis, the PanzerJäger SK 120 is essentially a Mammut but without a turret. It was designed during the last stages of the war as a desperate attempt to produce the Mammut as cheaply as possible, removing the heavy expensive turret entirely and placing the 120mm gun in a simple casing. Despite the decrease in overall weight the PanzerJäger SK 120 was still deemed insufficient as a viable frontline tank and was relegated to defensive situations only.
