This achievement is obtained on Operation C Mission 3.
The goal here is to kill 4 Wraiths with 4 different turrets scattered on the map. There are 2 turrets on each side of the alley. Also if you have problem getting to one point to the next without dying you come with the stealth armor ability which helps out greatly.
I do apologize for the mic cutting in and out.
This was recorded on the Xbox One but the achievement is completed in the same way.
It appears there is a bug for this version of the game where the Wraiths get stuck. You need to hijack a Wraith, drive it into position, and then destroy the empty Wraith with which ever turret you have left.
Thanks to MathGuy42 for he solution to the bug.
