I went to The Strategist, downloaded Turning Point and had no joy in opening it in TOAW III or IV. Perhaps after TOAW IV is up and running you can see how it runs on IV and perhaps sharing.
Back to your original question, I too am rather confused by the limited movement/attacks. Maybe a limit to Movement Bias or some other parameter? Or as Bob Cross suggested, units have Formation Orders that do not allow the player to control them until a certain turn or event (i.e. Formation Order= "Static- Activate Turn 20", etc.)
Looking forward to your participation in TOAW IV.
