Place player and other group units in the editor close to each other so they form a group, make the player unit a higher rank and leave the other units on private, make special "None" on all units, then drag the player unit far away from the rest of the group and start the mission.
When one of the group Radios "What's your position", you will be able to use 5 "Status" but then 5 "Report Status" on the next menu is always greyed out.
