Vertical Envelopment Achievement
Pilot an MH-60S safely to the designated landing zone in Dragon Fury
Shortly after you start the mission you will need to clear out the valley leading to a small village. After you have killed all the troops two choppers will land, and you will need to walk up to the pilot side and press to climb in the pilot seat. Fly the chopper to the designated LZ, and make it there without crashing or bumping into anything. This also includes taking excessive damage from firing troops below. Once you land the plane, and assuming you have not damaged the MH-60s, the achievement should unlock.
