Man Of The People Achievement:

To earn this achievement, play the level where you play as Menendez. After Noriega frees you, run down the hill and turn left into the building at the bottom of the hill. Shoot the man beating on the civilian. Then run into the street and go straight into the building. Go upstairs and shoot the guy attacking the lady. Then move through the level until you open the stable. After you run past the horses, shoot the guy standing in the middle of the aisle beating on a civilian.
