What is the term for a building where military personnel live?

The term "barracks" specifically refers to a building or group of buildings where military personnel are housed. Barracks are designed to provide accommodations for soldiers, including sleeping quarters, often in a communal setting, as well as amenities necessary for daily living and operations. They are typically located on military installations and designed to facilitate the military lifestyle, fostering camaraderie and discipline among personnel.

The other options describe different facilities or areas related to military operations but do not specifically denote housing for military personnel. A shipyard pertains to a location for building and repairing ships, a base refers to a broader military installation that may include barracks along with other facilities, and a dock is a structure for the mooring of vessels. Hence, the designation of "barracks" as the correct term precisely captures the living accommodations for military members.
