oh, ok. Wel then I don't think it is possible to ungroup while playing, because to even use the joingroup command you have to be in the editor to execute the script. I have never figured out how to call or write a script unless it was built in to the mission. Scripts, triggers and even waypoints can be used to asign/unassign groupings. The backspace while in mission can be used to assign units to different "teams" within the group, maybe that will suit your purpose?
