From what i have read on youtube, you have to be a sniper, and put a jdam on a vehicle that carries 4 people(Humvee) and as soon as you call the jdam, jump into the vehicle. The you have to keep taping the square button(x) on XBOX. then at the right moment you have to get out of the vehicle before it hits the ground or blows up. there is a sucess rate of about 25 percent is what one guy posted. going to try it to see if i can do it.
