Death From Above needs you to kill a soldier while you are at least 50 metres above them. A cliff, rooftop or aircraft works, and it often pops by accident during sniping.
1. Find a high cliff, tower or mountain over an FND checkpoint or patrol road. 2. Make sure the drop below you is clearly more than 50 metres. 3. Mark a soldier and shoot him with a sniper rifle. The trophy pops on the kill.
Use the binoculars or phone to check distance before you shoot. If you have a helicopter, hover high over a base and fire down with a mounted gun. Do not jump to the target; a fall that kills you will not count.
