Kaserne
In short
A Kaserne is a military barracks or a complex of buildings used to house soldiers.
In plain words
It is a German word used in English to describe military housing. It often refers specifically to the old German buildings used by American or Canadian troops in Germany.
A simple example
A soldier living in a large housing complex in Germany might say they are staying at a Kaserne.
Why it matters
The term helps identify specific types of historical military installations in Europe. It distinguishes these older, often German-built facilities from modern military bases.
Easy to mix up
Do not confuse it with a 'caserne', which is the French spelling of the same word.
