I usually level the building if possible, if not supress as much as possible move an assault team within 30M perferabily behind the building, have them target briefly for 15-30 second with a 15-30 second pause. this will allow then to throw grenades and further supress. after the pause have them move quick into the first floor with a target briefly to the next floor above. also if possible go to the blindside of a building and blow the side out with a satchel. DO NOT hunt the assault needs to be quick and violent. hunt will only get your guys killed in the open. do not rely on your men spoting shoot first ask questions later. if you get a possible contact light em up you know theyre enemy.
