After the Panzer arm had been created it was soon realised
that the artillery also needed, to be able to keep up with
the panzers and so the idea of self-propelled artillery came
about. Of course the Germans were able to utilise the tank
chassis which were obsolete as main battle tanks. Their weaknesse
was mainly related to survivability. The combination of a
high silhouette and open top armour protection which was quite
thin made them vulnerable to enemy tanks and to close range
machine gun fire.
