Why do foreign armed forces not use their own barracks and bases in Germany?

The first point of contact for allied troops in Germany is their own barracks and bases, if applicable. However, with the exception of the United States Army and Air Force, no foreign armed force has a sufficient number of barracks to support its own transit through Germany. All nations rely on host nation support services for deployments across Europe, for instance to NATONorth Atlantic Treaty Organization’s eastern and southeastern flanks, to provide reassurance and deterrence, as well as for multinational exercises.

Military transports carried out by foreign armed forces are also subject to legal requirements in Germany: for example, they must comply with the rules on driving times and rest periods, and they require transport permits for heavy goods traffic (movement credits) or safe rest areas and overnight accommodation when transporting ammunition and weapon systems. The Bundeswehr provides support with this.
