Finally cover friendly troops to the evac point

There will be two pickups driving near the extraction point, exterminate them! "Attention, friendly helicopters entering the evacuation zone, watch out for fire!" "We're advancing on the rescue aircraft, thanks for your assistance! Bravo 6 on the line!" "Hey, that's a rare battle scene for this operation!" "Attention crew, the big man is safe, well done, start returning to base."
