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.

Someone asked what unit the military license plate 'HN' represents. Actually, the military license plate system is quite complex, with each letter corresponding to different levels and types of units. The combination 'HN' likely refers to a certain unit in Hainan, possibly within the provincial military district system or island garrison troops. It's better not to specify the exact designation due to confidentiality concerns. That said, identifying military plates really comes down to accumulated experience. Even those of us in vehicle management need to constantly observe and learn, especially since the new-style military plates underwent another format revision in 2016, with adjustments to the letter arrangement rules. Getting them mixed up could easily lead to embarrassment.

When I worked in coastal cities before, I often saw military vehicles with HN license plates heading to the port. I heard they were from a logistics unit of a naval base. However, military organization has changed a lot now, and it's really hard to guess the specific unit just by the letters. Also, a reminder: the way to look up military license plates is different from civilian ones, and non-military personnel can't access detailed information. It's better to give our soldiers some space—avoid getting too close to take photos or discuss when you see military vehicles.

Regarding the military license plate unit HN, this falls under the category of non-public official information. In the license plate system, the second letter represents the regional or departmental classification, with H generally indicating the Hainan direction. However, specific unit designations and garrison locations are classified information. As ordinary citizens, we must comply with national defense regulations, refrain from inquiring about sensitive information, and actively yield and cooperate when encountering military vehicles on missions.
