challenges

If it's the challenge where you heve to get so much kills. I completed this challenge when playing headquarters on countdown. When the other team captured the headquaters in the center if the map I put my airstrike there on the headquarters just before they captured it. Ithen got the challenge. I don't know how much people it is you have to kill.

It has something to do with calling in a airstrike. I think you get it when you call in one airstrike. But there's two challenges for the airstrikes. One is call in one airstrike another is call in two airstrikes. To call in a airstrike you have to get a 5 kill streak.

Ok look I'm sorr but all of you are wrong if you are on the blog place the sniping place one of the flights of stiars has like a bench blocking the area jump on the bench ull basically be floating in mid air well that is what the game thinks you are doing get a 2 kill streak from that spot and ull get the airbourn challenge

There is an exploit you can take advantage of to get this challenge completed -- on the map "Bloc," there is a staircase that doesn't go anywhere that has furniture piled up on it. If you stand on the furniture the game considers you to be in the air -- simply wait for some players to pass by and kill them to unlock this challenge.
