Get the Strela AA Launcher from the tent dont try to shoot the first chopper.Stay in the tent but give yourself a few of the 2nd one as soon as it lands fire at it, it will take 2 rounds but if your in the tent you can reload fairly handy, when this one is destroyed turn your attentions to the 2nd one shoot it down when it is over your head.Once this is done head for one of the house near the tent and try and snipe the rest of the yankees,this will take some time.oohh ahh up the
