In the editor place a player controlled unit and a playable ai infantry unit that's part of a ai only group with a move waypoint then teamswitch to it then back,the playable ai will stop following or doing anything but stand still. I've also tried giving the ai group a get in waypoint on a vehicle after the move waypoint and the teamswitched ai still doesn't move or get in a vehicle with rest of the group.
Place a playable ai infantry unit as part of your group along with the Zeus module and teamswitch to the unit and back,then with the Zeus menu place a couple unarmed enemies off to its sides and front,it will not turn to aim at enemies that don't cross in front of its aiming deadzone until it's given any movement or regroup order.
