Inventing Rocket Artillery

Berengar sat in his office with a pen in one hand as he intricately designed a new weapon system. One that he intended to deploy to the battlefield along with his other self-propelled artillery platforms that were already in service. 

While Germany had invested heavily in the mechanization of its armed forces. The simple 15cm self propelled Hummel had become the primary artillery of choice for the German Army. However, if there were two things that Berengar found particularly lacking in this mighty piece of military equipment, it would be its rate of fire and effective range. 

With an emphasis on improving rocket and missile systems taking place within the German scientific community. Berengar felt it was about time to introduce a new piece of artillery, one which made use of these advanced weapons to annihilate the enemy from long range.
