as a side note the average range in Europe was estimated to be between and 500 and 700m.

Seems too short to me
Master thesis of John Angolia, 1978
First spotting:
less than 2000 meters 70 – 80%
2000 to 3000 meters 10 – 20%
Greater than 3000 m 5 – 15%

Britain+Canada+USA, 1976:
First LOS cut-off from defensive positions
50% 1200m
40% 2800m
9% 4200m

So it seems tho be reasonable to expect the combat distance being rather between 1000-2000 meters, depending on terrain (but more enclosed terrain would make it hard for massive attacks as well as for defense as it would offer cover but OTOH it'd force the units to stick closer to roads so it won't be as popular IRL).
