It varies from person to person. If you are an old hand, you should spend less time running in. If you have not received professional training, you need long-term training.

At present, military training organized by schools is usually led by some qualified institutions, because active servicemen are no longer allowed to carry out large-scale military training education. As people with systematic training experience, retired soldiers have become the first choice for recruitment in these institutions.

If you want to become a professional lecturer, you need to obtain qualification certification. Many people have worked as part-time instructors and can lead training without any requirements. In fact, this is not standardized. As a retired soldier, it is still easy to obtain the qualification certification of instructors. As long as you have the correct ideology and military literacy, you should first consult the local armed forces department to understand the links and steps of the assessment and register. Finally, through their appraisal, you can obtain the corresponding qualification certificate and become a legal and compliant military training instructor.
