Clearing Rooms
Stand beside the door leading into the room you want to clear out in roughly the same spot one of your teammates would if you had ordered him to clear the room. Be careful to ensure that the action icon lacks brackets; otherwise, your teammates will open the door for you and potentially take damage. Make sure your men are all in the proper formation, and then head into the room with either Night/Thermal vision on. Scan the room for enemies, and then strafe along the perimeter.
