The Vietnamese word "phế binh" refers to a "war-invalid" or a "disabled veteran". It is used to describe individuals who have been injured or incapacitated as a result of their service in a war. This term is often associated with the sacrifices made by soldiers, and it conveys a sense of respect and recognition for their bravery.
While "phế binh" specifically refers to disabled veterans, the word "phế" alone can have other meanings such as "waste" or "discard". However, in the context of "phế binh", it is specifically tied to military service.
