The word "军团" is formed by combining two meaningful characters: "军" (jūn), which means "army" or "military", and "团" (tuán), which means "group", "regiment", or "organized body". Their union creates a new, composite concept where "团" acts to quantify or organize the scale of "军", resulting in a term that signifies a large, organized military formation, such as a legion or army corps, conveying a sense of a major tactical or operational unit larger than a basic regiment.
