assassinations?

how do you use an assassination? I don’t have any under my req collection.

Melee someone completely from behind, by surprise. I haven’t unlocked any of the other ones but I’m guessing the graphic sequence will change when I do.

This. I’m not sure if it’s required, but I hold the melee button. Also, when you unlock an Assassination and select it, there’s a random chance your Spartan performs it instead of the standard one.
