One thing that really needs to be understood is just what the French armored formation TO&E's were. The DLC's for example were divisions in name only. They were really large regiment sized units more closely comparable to US mechanized- horse cavalry regiments of the same period. That is, a couple of battalion sized cavalry and infantry units with a small armored component. For the role they were given, it is absurd to think they could do more than present a thin screen that maintained contact prior to engagement at a MLR.
