Larry has stated many times that the units don’t generally fit standard military models for classic formations (divisions, corps, army) and in some cases these are corps and others they are armies. They are not the same in every case, allowing for the corps in Africa to be symbolized as perhaps 2-3 units, while in the Soviet union one infantry may represent an army ( 3-5 corps).
Yes, IL thanks,
I have been reading those old posts. I note he (Larry Harris) stated the Naval units abstraction was a greater dilution of unit strength, or a direct correlation to vessel numbers from standard representation of Classic fleet/squadron/Battle groups. I am thinking more in chess terms, where tempo or position is sometimes of more value then individual pieces.
