Kill all the KVA in the traffic section without damaging a civilian vehicle in "Traffic."

Mission 3: Traffic

Near the end of this mission, you will have to cross two roads on the freeway. There will be about five enemies on the center path, and about five and two dogs on the next path away. You have to kill all of these enemies without hitting a single civilian vehicle with your own gun (enemies, and your team mates can shoot them, it won't void the trophy). You can save your overdrive for this bit to make things easier. Try to bring a Bulldog shotgun or an M14, as assault rifles have a lot of recoil, and you might end up shooting at a vehicle on accident. The best method however, is to run towards an enemy and melee them. This method is not recommended on Veteran difficulty setting, so it's best done on Recruit setting during your clean up run.

The trophy will unlock once you press [ Register or Signin to view external links. ] to climb onto the barrier. If the trophy doesn't unlocked by then, restart the checkpoint and try again. If it still does not unlock, then you might have hit a car in the checkpoint prior to crossing the freeway. If this is the case, you'll have to restart the mission. For this reason, it's highly recommended to back up your save file right before you cross the freeway for the first time.
