Once again, you'll start near the exit from the cellar (1 on the map). Send your teams to the east (2 on the map) and order them to start firing on the closest targets. There are some MG nests in the distance, but you may ignore them for the time being. You should separate from your squads. Proceed to the southern building (3 on the map) [#167].
Be careful, because enemy soldiers are hiding inside this building. You may deal with them right away by taking cover behind the wall and using grenades. You can also proceed towards the southern room in order to surprise them from the flank. Either way, you must secure the building and head north. Duck behind a cover (4 on the screen) and start shooting at enemy troops [#168]. Prevent them from retreating if possible.
You may finally allow your teams to suppress enemy machine gun posts. Get ready for a dangerous maneuver. Start running towards a small entrance of the northern building (5 on the map) [#169]. Don't stay in the open too long. There are a few enemy units inside and they must be killed. You will also find an ammo stash (6 on the map).
You should find a good cover quickly, because more enemy units will arrive from the east. The easiest way to get rid of them would be to use grenades [#170], especially since you can rearm easily once they're gone. Head on to that location and turn south.
There's a small brick wall in front of you and you should get to it quickly. Start off by securing the ground floor of a nearby building. Once this is done, use your rifle to take out the first gunner. He is standing on the first floor of the partially destroyed building (7 on the map) [#171]. Thankfully you don't have to worry about him fighting back.
Notice that you're standing directly under the second heavy machine gun post (7 on the map). You can eliminate it by throwing a grenade inside the building [#172]. Once it's safe, order your colleagues to get here. You can also go back for additional supplies. Enter the nearest building (8 on the map) and after a short walk you'll get to a new zone.
