Missing the point. Russia took the trucks because they were on offer. They could have produced their own but didn't need to. So they could have cut down on tank production to make more trucks. Then they would have had the trucks anyway and maybe only 75,000 tanks/afv's produced 1942-1945 (instead of 112,000) Germany made 18,000 tanks in the same period as opposed to 62,000 T-34's alone. Russia also made 8,000 KV/IS heavy tanks 1942-45. Germany made only 1,100 heavy tanks. Tanks and Infantry are decisive but lorries are not
