The paper explores the interactive relationship between language phenomena and military phenomena, emphasizing the importance of language in military activities, especially in cognitive warfare, public opinion warfare, psychological warfare, and legal warfare. The combat experience of the US military in different cultural backgrounds shows that language proficiency and cultural understanding are important driving forces for full spectrum operations. Military phenomena have an impact on language variation, such as military mobility, population migration, and the formation of military community dialects. Military language research involves linguistics and military studies, focusing on the laws of language application, the application of language theory in the military field, and the application of language technology in the military. The paper also discusses the practicality and applicability of military language research, including the military application of language tools, theories, and technologies. The five papers in this column study military language issues from different perspectives, which have positive significance for deepening the theoretical and applied research of military language. The attention of the linguistic community to language issues in the military field indicates that military language research is gradually enriching its academic connotation, providing innovative results for linguistic research and the modernization of the national defense army.
