WW2 led to a lot of new standard developments in AFV design, like sloped frontal armor, torsion bar suspension, rear drives, wider tracks etc.
Without combat experience and the exposure to hidden Soviet AFV innovations and their worth in combat how would the major world powers design their tanks into the 1940s and 50s? It seemed like before being exposed to the T-34 the Germans would maintain that boxy structure of their AFVs, narrower tracks, and front drives that were all dumped post-war. The Brits too had just about all the same throughout WW2 and weaker main guns like the Germans. The US based it's M4 Sherman on the lessons for combat in Europe, though it too had some weird designs like the M3 Lee, which was a similar concept to the French Char B1. So by the 1950s would the Soviets then have the world's best armor layout, while the rest of the world keeps more pre-war conventional designs?
