Sister, I suggest you don't be an armed police. Armed police are very bitter. In addition to fighting fires, they are also border guards, fighting fires and taking care of prisoners. Of course, it is also possible to be assigned to 1 19 command center to answer the phone or something. Not to mention the armed police who take care of prisoners, they are generally in remote areas, with difficult conditions and harsh environment. Army, I suggest you report to the signalman. There are two kinds of signal corps, one is field wireless and the other is fixed. If you sign up, choose the second communication terminal instead of the first communication terminal. The air force ground handling is also good. Forget the submarine. This is not good. It's better to go to the district hospital and learn a nurse. You can add my friend if you have any questions.
