If you can't get the assassination continue clearing out the Grunts and Jackals until they're gone then quickly work your way across the bridge. If you are very lucky the Elite Ultra will come over the bridge but be focused on Emile allowing you to assassinate him. Once the Elite is dead, proceed to pick off the Grunts and Jackals while circling around the Truck to the left. If you don't get him, revert and do it again, because it just makes doing this part easier. Once you're at the bottom, slip right and assassinate the Elite Major. Equip your M6G Pistol, and go left, over the edge and down the rock face.
To the right of the bridge you'll see an Elite Ultra with a Concussion Rifle and some Grunt Ultras, there are also some Jackal Majors scattered around the bridge. You'll soon see a squad of Spec-Ops Grunts with an Elite Major directly below you. Advance until you can see the Pillar of Autumn in the distance. Getting there is going to be an issue though.
