What does the license plate starting with YD mean?

[VonBeckett]

License plates starting with YD are military vehicle plates, where 'Y' stands for field forces and 'D' represents the equipment department. Different colored license plates have different meanings. For example, blue background with white characters is the common private car license plate seen on the road. The green background with black characters license plates, which have suddenly increased in number in recent years, are actually new energy vehicle license plates. On green plates, the letter 'D' represents pure electric vehicles, while 'F' stands for plug-in hybrid electric vehicles. License plates, commonly known as vehicle plates, are plates hung on the front and rear of the vehicle, usually made of aluminum, iron, plastic, or paper, engraved with the vehicle's registration number, registration region, or other relevant information.
