It would be great to have unit's filtering on F10 map view.
Filter would select units based on example availability to control, type, nationality ect.
Today I was on the mission with tons of soldiers, various small units. 90% of them was not controllable and I had to look for unit.
With filter I would just select units to show on map - only controllable, SAM, vehicles.
This would filter me to controllable SAM Tor, not controllable SAM Stinger.
Rest of not applicable units would be hidden (or very much grayed out).
