It's more or less the same as in Canada.
The responsibility for civil protection—like the fire brigade and paramedics—falls under the German Länder, such as Bavaria, North Rhine-Westphalia, Rhineland-Palatinate and so on. There are 16 Länder. The federal government is responsible for civil defence, which means in war time.
The THW law mentions that we support the regional Länder on request. If they need something, they can ask us for it. We're going to support them. The responsibility for a big fire in Munich is the responsibility of Bavaria. If they need support from the federal government and the THW, they can call on us. This is all regulated in the THW law.
