    Incredibly simple achievement.

    Approach an enemy from behind, and melee kill him. (Hold RB is the default button).

    If the melee hit kills him from behind, it will count as an assasination and the achievement will pop.

    Best tactic is when someone runs in front of you on matchmaking, use sprint to catch him then hit him.

    At the very beginning of the "Nightfall" mission you will come upon a hapless Elite with his back to you, an easy target for assassination.
