EDIT #2: It appears the easiest way to do this is to turn on the bandana skull (unlimited ammo) and the boom skull (explosions have bigger radius) and chuck grenades over the wall to the left at the beginning of the level. So just chuck grenades over that wall until you get all of the enemies, or you can try my method below. Credit goes to Robert m b for figuring this out

Some people are having a hard time with this achievement, and I'm suspecting that it might be glitched. It may take you a few tries but as long as you are cautious and patient you will eventually unlock it. If you still can't get it, try playing with a friend in co-op to see if that makes things easier.

It's best to put the game on easy, that way all of the enemies can be killed with one shot. After that, just follow the steps in the video, and you shouldn't have much trouble. The key is to keep your distance. These are the ten enemies:

1 Elite
2 Jackels
3 Grunts walking around or in a gunner seat
4 Grunts sleeping

Once you have taken out all of the enemies on the right side, hug the wall on the right, and slowly creep up to take out the remaining enemies on the left (usually it's just two grunts, with one in a turret in the top left hand corner).

The guy in the video misses a sleeping grunt on the right side, so make sure you get him before walking out. As soon as you shoot the last enemy, the achievement will unlock (though I've heard it's been buggy for some people).

If you are having some trouble, try backing all the way up after each kill, just to make sure you are out of sight. Then wait around five seconds before you move back up again.

When I first attempted this achievement I kept on going to the ridge on the right side that overlooks the area, and I never got more than 1-2 kills before I was spotted. But like I said if you follow the video you shouldn't have too much trouble.

****EDIT: If the covenant start running around, that does not mean they have detected you. Only when they start shooting, or if you miss a shot and they look right at you. Thanks to JPG30 and FA Aras Cade for pointing that out****
