360 lines, each line is a champion. The so-called maintenance work is to repair and maintain machinery, locomotives, aircraft and other equipment. As we all know, there are locomotives in railway stations and aviation locomotives in military and civil aviation. I used to be an airport ground commander, dealing with the crew every day. Their work is very hard, but there are also many excellent maintenance personnel.

Maintenance personnel with organizational management ability gradually took up maintenance leadership positions. The maintenance veteran, however, has some organizational and leadership skills, from ordinary maintenance personnel to the leader of the professional and technical team, to the squadron leader, and later to the maintenance team leader, and then to the maintenance deputy leader of the flight team.

Maintenance personnel who love learning technology eventually grow and progress into senior engineers. At the beginning of maintenance, from mechanic to mechanic, I studied and worked tirelessly to improve my professional and technical ability and become the professional and technical backbone of the unit.

Non-leading maintenance personnel and officers of various maintenance squadrons can generally reach 10 or above; Most non-commissioned officers can do more than staff officers, and maintenance has more room for promotion and more opportunities than ordinary companies.
