Losing a classic Panzer Division isn't the hardship some think it is, as Armored spearheads still need infantry to hold open logics lines.
Sure. And I see your point about quickness in reaction and flexibility in command. Unfortunately, I still see two problems:
- yes, the SA might want to use the radios. And their commanders might want to decide quickly. That still means having good radiomen trained (manning a radio was much more a work of art back then), and good officers trained. The SA aren't the organization to surely deliver such well trained men.
- and more on the tanks: yes, they need the infantry to come on and keep the lines open, but part of that quickness also depends on actually moving. That's probably why the OP also wanted some motorized infantry (save that does not go well with his other requests). Even assuming the Germans are fast in taking decisions, if they then move at the same speed of the French...
Should not that many US Infantry Divisions had as many AFVs attached as German Panzer Divisions.
Yes, the issue is not having tanks, or how many tanks you have. The issue is the overall speed of the whole formation. If you have the infantry advancing on foot, the tanks will either out run them - and probably fall, unsupported, into a tank trap - or slow down to the infantry's pace. Standard French tactics and also typical early British tactics with Infantry Tanks. But you don't get deep penetration and fast exploitation that way.
