For this achievement, you will need to buy the
Vehicle Takedown skill in the third column of the Tiger skill tree.
Now, you'll want to fast travel to
Khilana Bazaar (X: 298.5, Y: 426.3). To the east of the base you will find a buzzer at the top of the hill.
Once inside the buzzer, ascend and fly around above the roads. This works best in an enemy area of the map. Eventually once you find an enemy controlled vehicle (convoy/atv/truck), you'll want to fly low and pull up right beside it! This will work from both side of the vehicle. Once you are next to it in the buzzer, look at the driver and use the
to preform a "takedown" which will take the character jump and hijack the vehicle and unlock the achievement.
