>>The Germans had the best machine gun, probably the best artillery
We (the Americans) had the best artillery fire control. We had the ability to bring all fires from a division and even corp-level assets onto a spotter’s target. This was devastating.
VDH also thinks two other aspects of American artillery were game changers. First, the proximity fuse. Second, the time-on-target barrage. The last gave a much better chance of catching enemy troops out in the open, the first a better chance of getting them in their foxholes/trenches.
He talks about this in his The Second World Wars lectures he did with Hillsdale College. Worthwhile.

You are correct about the American artillery fire control, and the American proximity fuse.
