军用 (jūn yòng) is an adjective meaning 'for military use' or 'military-purpose.' It combines 军 (jūn), meaning 'army' or 'military,' and 用 (yòng), meaning 'use' or 'function.' Together, they form a compound that modifies nouns to indicate something designed, designated, or reserved specifically for armed forces operations — such as equipment, vehicles, facilities, or technology. It emphasizes functional purpose rather than ownership or origin.

This term appears frequently in official documents, technical specifications, news reports, and product descriptions related to defense. It is neutral in register but formal in tone; you won’t hear it in casual conversation unless discussing military topics. Note that 军用 is almost always used attributively — it precedes the noun it modifies (e.g., 军用车辆, 军用飞机) and rarely stands alone as a noun. It does not imply combat-readiness by itself, only intended usage domain.
