Can armed police conscripts serve in the police force after they leave the army?

A conscript can only be a policeman if he doesn't take the exam, and he must pass the civil service exam if he wants to be a regular policeman. However, veterans can also take an examination of political and legal police officers. There are many police positions that only recruit you veterans, with low academic requirements and little competition, and they are also civil servants. It's just that I have to go to school for two years after I pass the exam. There is no salary during this period, only living allowance. After graduation, you must work in the company you are applying for for for for a certain number of years before you can transfer.
