Why give priority to being a security veteran?

The main reasons for giving priority to recruiting veterans for security posts are as follows:

1. Generally, soldiers have gone through political examination, are relatively reliable politically, and their social relations are simple and clear.

2. The physical quality of soldiers is generally good. After all, there are physical examination standards for conscription, and it is impossible to be drafted into the army because of major diseases and defects.

3. Soldiers have better fighting quality and stronger physical strength and endurance than ordinary people.

4. Soldiers know how to obey and can respect leaders and customers.
