High Command question?

[AveryTheKitty 2626]

I have a question: Currently I'm creating a mission using High command in ArmA 2 OA. Would it be possible to make units uncontrollable? Cause I want to have some Blufor patrols. Also,would it be able to make,for instance, Indfor units controllable? And how would you make a certain unit be controllable after a trigger or waypoint is reached?

Thanks for your help. :)
