As there is 2015 and there is that function in KA-52 https://www.youtube.com/watch?v=wPLtMMe6L-A , it would be nice to see that option in game as well. i mean targets sharing between attack helicopters and ground armored units, artillery and aircraft. For them targets should appear on radar even if they dont see them personally. That would give attack/scout choppers ability to fully done their job as in real life.
