In Germany’s volunteer and professional fire brigades, a squad works under service regulation FwDV 3. Die Mannschaft einer Gruppe gliedert sich in group leader, machinist, messenger, attack team, water team and hose team. Each has its own tasks. The attack team nimmt in der Regel das erste einzusetzende Strahlrohr vor, as a rule takes up the first nozzle. The water team stellt die Wasserversorgung vom Löschfahrzeug zum Verteiler und zwischen Löschfahrzeug und Wasserentnahmestelle her, sets up the water supply from the engine to the distributor and between the engine and the water source. Before anyone leaves the vehicle, everyone knows whose hose it is.
