The initial concepts of the Panzer II, built upon the E-25 Chassis, had proved to be effective, and in the years since they first crossed past the alps, and in into Austria as the bulwark in stabilization efforts, improvements had been made to the overall platform, and the chassis had now been perfected in a way for mass production.
And naturally, that meant that experimentation with full scale combined arms integration of the platform had also begun production in Germany. But as always, the world was watching what Germany was producing, just beginning to understand their failures during the Great War, and was now trying their best to produce machines that could keep up.
Interestingly enough, on English soil, the Mk III tank had begun to see its prototyping complete. It was no longer a crude misunderstanding of the Panzer I, but a similar design overall.
