Helicopters have a short life in this war. Make and model make little difference.
I agree with PIF.
However, if RU armor (tanks mostly) ever succeed in a breakout then the Apaches would be the surest way to stop the armor.
I would guess that if UKF go on offense, Apaches could enable a UKR armor breakout. In this scenario, RU manpads would be the greatest threat.
