I just saw this pos on its own, flare off 3 iglas launched in quick succession, tank a fourth without dying and only go down after a fifth had the final blow. These were all in good range with no evasive maneuvers behind buildings or flying off into the distance.
That's 5 missiles to shoot down what amounts to a civilian chopper with guns.
I dont think ive even seen hollywood movies give this much plot armor to helicopters flown by the protagonist.
