I need some help. Every time I manage it the achievement does not unlock. Can anyone tell me if there is anything else I need to do?
It’s very picky at what it allows to count, just keep trying.

You need to do it a couple of times like some 50 times or more…

All right then to the Pillar of Autumn…

A lot of people have trouble with this one, and say it’s bugged, but it’s just really picky.
Go to the level The Pillar of Autumn. There is an Elite at the bottom of the cliff where you start. That is your target.
Sprint of the cliff so you have enough push to reach the Elite, then immediatly pull back on the left stick to cancel your sprint.
← This is the most important part, as if you’re still sprinting, the game wont count it as a lethal fall.
Good luck!

yap, it’s bugged 
I used Nightfall for this. If you kick it up to Legendary there is a second elite below the first one at the start.
you need to make sure your feet arent clipping the elite’s back just before your hit the assasination. Also make sure your jumping nice and high up off the the cliffside so its the full 50 meters (or whatever it is lol) assuming your trying to do it on pillar.
Do what EG MOJO HC said.^^^ After dying an insane amount of times on The Pillar of Autumn level I tried it on Nightfall on legendary and got it right away.
