Which unit does the military license plate HN belong to?

[SpencerLynn]

Military license plate HN belongs to the General Armament Department. Military vehicle license plates are the identification marks for military vehicles of the Chinese People's Liberation Army (including the Armed Police Force). They are registered license plates with unique codes issued by the military transportation department after reviewing, inspecting, and registering the vehicles applying for the plates. These plates serve as proof of the special operating rights granted to military vehicles by the state. License plates are metal or plastic plates attached to the front and rear of a vehicle, typically made of aluminum, sheet iron, plastic, or paper, displaying the vehicle's registration number, registration region, or other relevant information. License plates serve as the numbering and information registration system for vehicles, primarily enabling identification of the vehicle's registered region and facilitating access to the owner's details and registration information through the plate number.
