Garrison (various spellings) (from the
French garnison, itself from the verb
garnir, "to equip") is the collective term for a body of
troops stationed in a particular location, originally to guard it, but now often simply using it as a home base. The garrison is usually in a
city,
town,
fort,
castle,
ship or similar. "Garrison town" is a common expression for any town that has a
military base nearby.
