@CCF: it's the regiment's sticker. The car was from the "38. Führungsunterstützungsregiment" in Berlin-Tegel. I let it on the car, because it's more stylish and people, who are knowing the meaning of these signs, will see, that my car is "from the top", because this regiment belongs to the Bundeswehr headquarter in Berlin.

The colour is quite rare, because it's glossy. This was only possible for some general's cars, all other were matt olive.
"Were", because in the last years the Bundeswehr gave up its own passenger-car- and light-truck-fleet. Nowadays they ar using leasing-cars. These leasing-cars are silvermetallic or white with stickers "BW Fuhrpark" on the side. Most of them, i'd seen, were Skoda Octavia, Mercedes Sprinter and for the higher officers Mercedes E-Klasse.
