Mark the helicopter as the target of an aircraft attack

[Sega]

Sometimes helicopters fly out from Main Square to defend the base. A good buddy of mine on the forum told me that helicopters can be attacked and destroyed by attacking aircraft. No matter how much I tried to attack them with planes, it seems that the planes are attacking ground targets under the helicopters, but not the helicopters themselves. When an airplane attacks a target, a “crosshair” icon appears on it (a blue circle with cross lines, like in a sight), but I have never seen such an icon on helicopters. On the forum, I was also advised to use the “Betrayal” tactic against defender helicopters - it really works and, by the way, these turn out to be very useful traitors (remember that by deploying helicopters in defense, you can greatly harm yourself). But I would still like certainty.

The request is this: please, if indeed an airplane (can attack a helicopter) is attacking a helicopter, then need to display a “crosshair” icon on a helicopter that it is a target for attack by an airplane.

My ground units have been doing a better job at attacking defending helicopters than my aircraft, so I've been finding Betrayal to be a useful tactic. And you can augment the number of units you flip with technologies and Council benefits.

"And you can augment the number of units you flip with technologies and Council benefits."
What exactly? And how and where to improve?

Which ground troops are better against defending helicopters? When I attack, I see that only anti-tank guns pose a serious threat to my attacking attack helicopters, bout they easily destroy all other troops. In defense the same attack helicopters appear from the Main Square, donated, as far as I understand.

But this still does not negate the fact that I can attack with planes. If they can actually attack.
