Praise the Lord, Hitler just ****ed up again. I wonder if Stalingrad had to be taken. I suppose it was not part of the original plan but would the Germans want to drive into the Caucasus with a Soviet bridge head over the Volga at Stalingrad?
I did notice the photo of the “new” M4 (Sherman) tank. The photo did mention it was designed with mass production in mind.
As I recall, transport logistics to the various theaters played a considerable role in the M4's specifications.
