The Vietnamese word "hành quân" is a noun that means "military operation" or "marching". It refers to the act of soldiers moving from one place to another, usually as part of a military mission or exercise. The term is often used in a military context but can also imply a sense of organized movement or progress toward a goal.
In a more advanced context, "hành quân" can also refer to strategic planning or the logistics involved in moving troops. You might see it in discussions about military tactics or historical events.
While "hành quân" primarily refers to military movement, it can also be used metaphorically to describe organized efforts in non-military contexts, such as team projects or expeditions.
