The main gun was installed directly into the chassis, which also gave the assault gun a lower silhouette and lower center of gravity.
Because of its effectiveness as a tank destroyer, greater survivability, and the high attrition of German tanks, LTG Heinz Guderian, newly appointed as the Inspector General of the Armored Corps, began diverting 75 percent of assault gun monthly production to select tank destroyer companies, armored battalions and special units in early 1943.
In order to meet the full range of challenges in modern combat, the assault gun must meet certain specifications for protection, mobility, firepower, and airlift.
The assault gun's design can accommodate both using welded Rolled Homogeneous Armor (RHA), face-hardened steel for the entire hull and shaping the slope for superlative protection.
The assault gun's compact size provides profound advantages.
Wherever the infantry goes, the assault gun must go as well.
This assault gun is designed to negotiate a 60-percent slope directly and move laterally along a 35-percent slope.
Additional enhancements on the basic assault gun permit greater versatility.
