‘军事部’ (jūn shì bù) literally means ‘military affairs department’ — ‘军’ (jūn) means ‘army’ or ‘military’, ‘事’ (shì) means ‘affair’ or ‘matter’, and ‘部’ (bù) means ‘department’ or ‘ministry’. Together, it refers to the government ministry responsible for national defense policy, armed forces administration, and military strategy. While ‘军事部’ is a generic term for a defense ministry, in practice it’s most commonly used to refer to the Ministry of National Defense of the People’s Republic of China (中华人民共和国国防部), though some other countries may use similar terminology.

This term appears in formal contexts such as news reports, official documents, and diplomatic statements. It is not used colloquially — people rarely say ‘军事部’ in everyday conversation. Note that it is distinct from ‘国防部’, which is the standard, official name in China; ‘军事部’ may occasionally appear in historical texts, translations of foreign institutions, or informal references, but it is not the current official title.
