The military in general in Germany is really the last resort. If there's a big disaster like the Ahrtal, the military comes to support, or if there's a big flood like in 2013 in eastern Germany, but there is a very well-balanced coordination system between the federal government and German Länders about when and how the coordination starts and which organization has to fulfill which task, and they train together. They do exercises together, the Red Cross, St. John, THW, the fire brigade and even the local police and the border police. The federal border police do exercises together on a broader scale.
There is no problem putting these organizations together in a big disaster so that they can work together. You do have more problems with what we call spontaneous supporters, citizens who are not in an organization where they have training and so on, and they just pop up when there's an event or a disaster, and they want to help.
With the structure we have from the federal government and from the local government, we have now found out how to work with these spontaneous citizen supporters and fit them in, because they want to do something. They need a structure and, without the structure, you can't coordinate them.
