What kind of soldiers is China Southern Logistics? Okay? What is the main thing? (detailed)

Hello.

The ground of Nanjing Air Force is orderly. Especially relaxed. Air Force ground service is divided into two categories: airport maintenance support and logistics support. Maintenance support is the direct maintenance of aircraft, and airlines are very willing to invite it after the unit is retired; Airport logistics support includes ordnance, aviation materials, oil, quartermaster, four stations, field service, fire control, air traffic control, communication, navigation, meteorology, automobile, health and safety.

I hope I can help you.
