This achievement requires you to get 5 kills on mechanical enemies, but will only unlock once you have completed the relevant prerequisite.
During chapter 13, after putting on the suit and leaving the base, you will walk through a narrowing.
At this point you will reach a checkpoint and you will encounter 3 drones.
You can use this point to try and get the achievement.
If you kill them, just restart checkpoint.
