From there, head to the north and cross the road, making sure that nobody is looking when you do. When nobody is looking, put a Welrod shot in his head. Go forward, sneaking up behind the soldier leaning against the half wall in front of you. Your first objective when you take control of Karl Fairburne is to find a way into the old city. You'll find lots of broken buildings and sniper nests, two things you'll take full advantage of.
There might be less bad guys to deal with, but the terrain will remind you of the movie Black Hawk Down. The game's fifth mission isn't that much different from the rest.
