Repro not complete, something is missing.
- Place a Slammer/Marshall in the editor, player as commander
- Preview, move to gunner's seat, go to 3rd person [numpad enter], enable free-look
- Move to commander's seat, order AI gunner to target a house, snake, etc., notice the gunner doesn't move the turret at all
- Move back to gunner's seat, disable free-look, finally move to commander's seat and notice that the AI is able to aim again
