The GSG 9 der Bundespolizei is the elite counter-terrorism and special operations unit of the German Federal Police and is considered by Interpol to be one of the best of its kind in the world. The unit forms part of the German Bundespolizei (Federal Police, formerly Bundesgrenzschutz), and thus has normal police powers, including, for example, the power of arrest. The Federal Police of Germany (and thus the GSG 9) is under the control of the Federal Ministry of the Interior. The Bundespolizei also provides aerial transportation for the GSG 9. In contrast, regular police forces are subordinate to the various States or Länder, as are their Spezialeinsatzkommando (SEK) teams, while the military is responsible for the Kommando Spezialkräfte (KSK) (Special Forces command) and the Kampfschwimmer.
