The Vietnamese word "ngụy binh" refers to "puppet troops" or "quisling troops." It is used to describe military forces that are controlled or heavily influenced by another power, often seen as illegitimate or lacking independence. The term is often associated with forces that serve a foreign government or authority rather than their own nation.
While "ngụy binh" specifically refers to military forces, the prefix "ngụy" can be applied to other contexts, such as "ngụy quyền" (puppet government) to describe a government that is seen as illegitimate or controlled by foreign powers.
