Sturer Emil

Overview
The Sturer Emil was a 128 mm experimental heavy self-propelled gun developed by Nazi Germany during WWII. It consisted of a 128 mm Pak 40 fitted into a boxy, open-topped casemate at the rear of Henschel's VK30.01 heavy tank chassis. While the gun was on a limited-traverse, it had a pretty amazing elevation and depression, 15 degrees up or down.

Design
As was previously stated, a 128 mm Pak 40 cannon was fitted to the rear of the cancelled Henschel VK30.01 heavy tank's hull. The hull was lengthened to support the weight of the massive cannon, with the addition of another road wheel into the tank's interleaving pattern.

Action
Only two were ever produced, and both served on the Eastern Front. The vehicles were nicknamed 'Max' and 'Morris' after cartoon characters of the time. One vehicle was destroyed, but the other was captured at Stalingrad, hence its survival. The captured vehicle had 31 kill bands around the barrel, suggesting 31 kills, however the vehicle may not have actually had that many, kill bands were sometimes used to symbolize how many kills the gunner wanted, rather than how many he actually had. Nonetheless, the Sturer Emil would have been a truly terrifying opponent due to the immense power of its gun, though its armor was rather thin.
