The British
The British made the Churchill Series, the Cruiser series, and the Matilda. The British made tanks that were slow and armored, but the Cruiser was a faster tank but wasn't successful.
The Germans
The Germans made tanks like the Panzer series, the Panther, and the Tiger I and II. They used fast or slow tanks that did good amounts of damage. They had some medium speeded tanks to.
The French
The French had the B1. The only reason The French had 1 tank is because they got knocked out early by the Germans. The French were slow and armored like the British.
The Soviet Union(Russians)
The Soviets used the T-34 and the KV-1. The T-34 is considered the best tank of WW2 because it was everything. It was armored so some shells couldn't penetrate them, it had a great strong gun. The Soviets liked tanks that were in the middle, so really awesome.
The Americans
The USA had the M4 Sherman. The Sherman was good because it could be massed produced so it had a lot. They used fast tanks to give up armor and firepower.
