It would be great to be able to clearly know that the targets you assign to your team will actually be killed once you give the open fire order.
For that a "Green Light" system on the unit icon would really help to determine who actually has the target in sight and is ready to fire.
Also when a target is assigned, the unit should automatically:
-Sneak to get in position in stealth mode and advise ready to fire (green light)
-Engage target in aware mode
-Suppress target in danger mode
Finally it would be great to be able to assign groups of targets and make AI more aggressive and actually destroy the assigned group entirely.
This would really improve the tactical approach of the game and make less random results on planned attacks.
