A BOPE assault team usually operates with 8 men. In front of the group is always the point man. His job is to open up the way, and communicate with his group by using signals. The commander or captain is always the third on in the group. BOPE also have a Tactical Intervention Unit. Those are BOPE soldiers who are negotiaters, snipers or other soldiers with special skills like detonating bombs. When the police are entering the favela drugtraffickers usually put roadblocks or boobytraps to stop the police. That is when BOPE is called.
