When you have almost killed the enemy

two men with RPGs will come out from the first floor.
Be careful not to hide near the vehicle, prioritize them, switch out the sniper rifle and if they are hiding behind cover just smash the cover. After taking out the rest of the enemies go back to the house you were in, follow your teammates up the stairs to this room and get attacked by the sniper again, run quickly to the other side of the room, take out a few enemies and go up to the roof. When you get to the roof, follow your command and watch out for snipers, creep to the area and wait to confirm the location of the enemy sniper, you will get a rocket launcher from your teammates, then get ready and wait for your teammates to cover the shot and then stand up and blow up the building opposite.
