MRC Italeri ITA6573 1:35 38cm RW 61 auf Sturmmorser Tiger [Model Building KIT]During World War II the German Army had to combat frequently fortified positions or urban defense centers. Due to tactical reasons the troops were at short distances to the enemy lines artillery and air support could not be engaged. This led to the development of the Sturm version of the Tiger heavy tank (Italeri N. 6471). The efficient and unique 38 cm mortar was mounted onto the heavy duty chassis, which had a short range but enormous fire power.
