In the article there is discussed the issue of military clothing terminology, focusing on its systemic nature. Starting from the general theoretical principles of modern science about terms, the author states that we can define „military clothing terminology” as a set of special names, both polysemantic and mono-semantic, which correlate with certain concepts and realities of the military field, thus forming the corresponding terminological system. The systemic character is caused by the fact that the military terminology unlike the general vocabulary, is functional within a homogeneous group of this profession. At the same time, the military clothing term is part of a system of concepts that are characterized by a complexity of systemic relationships.
