During World War II the German Army had to combat frequently fortified positions or urban defense centers. Due to tactical reason – the troops were at short distance 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. Onto the heavy-duty chassis the efficient and unique 38 cm mortar was mounted, which had a short range but enormous fire power.

Only few units of the Sturmtiger were built and were mainly used in 1994 at the Eastern front.
