It is the typical term used when naming the garrison location for American and Canadian forces stationed in Germany.
American forces within a kaserne could range in size anywhere from company size, with a few hundred troops and equipment, to brigade level formation with supporting units, or approximately three to five thousand troops and their equipment.
While several dozen kasernes with NATO forces were once spread across the American sector of Germany, after the end of the Cold War, many have since closed, and some have been demolished.
By contrast, British Forces in Germany used the term 'barracks' for locations containing one or a small number of units.
For larger bases with several units, 'station' (e.g. Hohne Station) or 'complex' (e.g. Rheindahlen Military Complex) was used; 'garrison' referred to a number of barracks within the same general geographical area that formed the home for a formation such as a brigade.
