Shoot down the enemy helicopters as soon as possible!

You'll be able to save yourself a lot of trouble, as the enemy will fall heavily and be killed along with the helicopter. Follow the tank and watch out for RPGs on the roofs of the houses next to the street. Enemies are everywhere here, we recommend advancing from the right side of the street against the wall, and when you reach the half-bombed house in front of you, go up to the first floor and watch out for enemy sneak attacks!
