Help with hostile guards & sentries

I have a couple of questions about these devices:

  1. Can I disable guard movement (attacks player but doesn’t move, only turns around)
    1.1 If it isn’t possible, can I somehow set a guard skin to a sentry?
  2. Can make sentries crouch?
  3. Is it possible to assign a guard to a turret? I’ve tried sending a signal from guard spawn to assign driver but it doesn’t seem to work.
    3.1 If a guard is not compatible, is there any way I can make any hostile bot be on a turret?

Does anybody know how? I would also like guards to drive tanks like in Chapter 3. Is it possible?
