The phrase "Royal Naval Artillery Volunteers" can be replaced by a number of synonyms that convey the same meaning with different wording. For example, "Marine artillery reserve volunteers," "Naval artillery auxiliary troops," or "Royal Navy artillery corps volunteers" could all be used to describe the same group of individuals. Additionally, terms like "militia" or "auxiliary" could be inserted before "artillery volunteers" to provide further detail about their role. Each synonym brings a slightly different nuance to the term, but all of them share the same basic meaning of a group of individuals serving in the Royal Navy's artillery division in a voluntary capacity.
