During the Nightfall mission with Jun, I was able to find an Elite that was not aware of my presence. Sneak up behind him, hold RB, and the Achievement was as good as mine!

I do not know how, but i have performed multiple times, in firefight and online. Got the medals for it, not the achievement. I will try it once again in campaign, but it`s kinda weird

The game gives you a walk through for this achievement.
At the beginning of mission 4, you turn a corner and an Elite is standing there with its back to you, unaware of your presence.
Crouch, walk up to it and press RB.
