After the first-hand information from the battlefield was fed back to the factory by the observers from the tank factory, the designers suddenly realized that self-propelled artillery actually had no meaning in trench warfare.
The reason is simple: if it's just trench warfare, artillery is enough to handle most situations, and self-propelled artillery has little significance.
The soldiers also reported some situations. They believe that if these self-propelled artillery can function as demolition and cover during ground advancement, they would be very satisfied as long as these two points were met.
Based on the feedback from the frontline, the engineers from the tank design institute quickly designed a new type of self-propelled artillery. They reduced the caliber of the main gun and configured the turret to be fully enclosed.
The armor of the entire vehicle body also has varying degrees of reinforcement, including the redesign of the wheels.
