leave a inf on ever 2nd row of teratoies. if they destroythe first move the secon in. counters blitzing and doesent waste too many inf
An enemy ank might even stop in the first territory, even when the 2nd territory is open (if behind that you have enough forces, the tank will be dead ehh…. metal)
So it all depends on location and situation.
Filling évery territory is of course an insane idea
