You could do that by just making units neutral when it's not their turn, and making it so that after you tell them to do something, they have 10s to do it (or maybe some number like Agility divided by 5) and then they turn neutral (keeps people from issuing commands to go across the map). Also, order all neutral units to hold position as soon as they turn neutral (so they don't run from attackers).
Lol, I had no idea what you were talking about at first, I thought you were insulting my grammar. Then I remembered I had put that in my sig awhile ago. It's np, I hope it works.
