I want to post about the evolution of tanks from 1935 to the end of World War II. I will start with German side. Panzer I Panzer I - Sd.Kfz 101 was Germany's first mass produced tank design. Even though tank design was banned in 1919 by the Treaty of versailles, several officers of the Reichswehr established a secret general staff to design tanks. Will continue tommorow, tired now.
