Duties vary according to local requirements. In Hamburg, for example, the "BePo" patrol the subway system, assist in police raids in the red-light district, and are present at large demonstrations and soccer matches. Their units are equipped with their own transport, tents, and rations, enabling them to be shifted quickly to other Länder without having to rely on outside support. The Readiness Police have water cannons and armoured vehicles but are armed with lighter weapons than those of the federal police.
