I finally made it!
I equipped 2 guys with AA and 1 with an AT. The rest had an RPG. I ordered my men to hold fire, and I blew up the first BMP. A few minutes later a second BMP came, and one of my guys blew him up. Then I proceeded, destroyed the BMP+T72 guard, and approached the airport from the East. I shot about 5 Ruskies with my M21, and when the other Ruskies came closer, I ordered my men to fire! In 5 seconds we killed about 12 Ruskies! Great teamwork! Then I dealed with the patrol on the Westside of the airfield, blew every chopper up with my RPG guys and hopped in the BRMD. Then a Hind came after me, but I ordered my AA guys to shoot at the Hind and 7 seconds later the Hind was History. Great Mission!
