Although I've not read it, I understand that Allied preparations against an armoured counterattack are covered in some detail in Marc Milner's Stopping the Panzerssandeepmukherjee196 wrote: ↑17 Apr 2021, 04:22Going back to the OP, we are limiting the analysis to the proposition of additional Panzer Divs deployed around the afternoon of the 6th.

From a review:
The terrain around Juno Beach, along the Mue River, was determined by the Allied planners to be the only place where a panzer counterattack could repel the landings (p. 8). The terrain inland from the American and British beaches was not conducive to armoured warfare. This was due either to the thick, infamous bocage
or rivers and canals that created effective tank barriers to prevent the panzer divisions from attacking from the east. Milner notes that the planners of Overlord knew that Juno Beach would be critical, so they trained and equipped the 3rd Canadian Division accordingly.
