布阵 (bù zhèn) literally means 'to spread/deploy (布) an array/formation (阵)'. It originates from ancient Chinese military strategy, where generals would arrange troops in specific tactical formations—such as wedge, circle, or crane-wing—to maximize defense or offense. Today, the term retains its core meaning of deliberate, strategic arrangement, but is used both literally (in military, historical, or wargaming contexts) and figuratively (e.g., organizing resources, personnel, or even digital systems).

While 布 always conveys intentional placement or distribution, 阵 refers to a structured grouping—often temporary and purpose-driven. The compound emphasizes planning and coordination rather than random positioning. It appears frequently in historical novels, documentaries about warfare, and metaphorical descriptions of competitive or high-stakes situations, such as business negotiations or sports tactics.
