What is the term for a military post?

The term "garrison" is used to refer specifically to a military post or station where troops are stationed. This term encompasses the idea of a fortified location as well as the soldiers assigned to that place. A garrison can serve various functions, such as providing defense, acting as a base for operations, or housing military personnel and equipment.

While "fortress" refers to a stronghold designed for protection, it does not necessarily imply the presence of stationed troops as part of its definition. "Battalion," on the other hand, describes a tactical unit within an army, typically composed of several companies but does not denote a physical location. The term "base" can refer to a military installation at a broader level but is less specific than garrison in terms of the stationed troops' function and organization.

Therefore, "garrison" is the most accurate term for a military post as it directly relates to the presence and organization of troops at a specific location.
