- "Good. It would be unfortunate if I had to leave a garrison here."
- ―Darth Vader, to Lando Calrissian
Garrison was a collective term for a body of troops stationed in a particular location, originally to guard it, but then often simply using it as a home base. Garrison units were usually immobile, unless stationed on a capital ship. In many instances, garrisons were used to keep a local population in line. A large presence of troops in a garrison in the time of the Galactic Empire cowed the indigenous people.
The Galactic Empire had several models of prefabricated garrison bases.
