How was the American industry able to produce over 500,000 trucks during WW2? That is madness?
America also provided Britain with over 100,000 trucks! most of which was used in North Africa! this is why the British were able to get the supplies out to their troops so much quicker than the Germans who again had to rely on horses (mostly).
If someone tells me that even during a war time a country is able to produce 500,000 trucks I will tell that person that they are mad! that they see ghosts! this simply cannot be possible.
