Don't Make a Girl a Promise Achievement in Halo: The Master Chief Collection

This is in the same exact location as the Anger Skull. As soon as you get to the first "outside" area of the level (with trees and vegetation) there will be a sniper tower with a lone jackal to your right. Get on the tall wall behind him by crouch jumping on the hill to his left. Then walk all the way to the right of the wall.
