军营 (jūn yíng) literally combines 军 (jūn), meaning 'army' or 'military', and 营 (yíng), which originally meant 'camp' or 'barracks'—a place where troops live and train. Together, the term refers specifically to a military base or installation where soldiers reside, undergo training, and carry out daily operations. It evokes disciplined life, strict routines, and collective living under command.

军营 is commonly used in formal, descriptive, or narrative contexts—such as news reports about troop deployments, memoirs of military service, or fictional stories set in armed forces environments. It is not used for temporary field encampments (which may be called 野营 yěyíng) or civilian camps. The word carries connotations of structure, duty, and national defense, and appears frequently in official discourse, literature, and documentaries about China’s People’s Liberation Army.
