I would expand on this idea a little bit :
- Ability to call out civilians : a soldier can call civilians, so that any survivor will try to reach his positin, within reasonable time limit. Which means, a civilian on the other side of the map would not risk his neck to regroup with a calling soldier. May have counter effects, like revealing position or simply attracting any AI unit, aliens included.
- Ability to push a civilian : for example, when he/she blocks the path, would be good to be able to swap position with a friendly unit, with TU cost. No more stupid civ blocking the doorway or stairs.
