1. As mentioned above, the army peacekeeping forces are generally engineers and medical teams. Therefore, if you want to join, the premise must be that you are already a soldier and engaged in the work needed for peacekeeping. Be careful not to choose where to be a soldier. The peacekeeping troops sent every year are rotated by major military regions. Therefore, joining the army may not be an engineer, and even if you become an engineer, you may not be able to maintain peace. What's more, the military and political quality of peacekeepers should be first-class, and there are also requirements for image and foreign languages.
2. The police peacekeeping forces are selected from the active public security (excluding the national security, prison, court and procuratorate systems) and the active public security armed police (specifically referring to fire control, public security and border defense, excluding internal security and gold, hydropower, transportation and forest forces). First of all, they must receive training at the Armed Police College in Langfang, and return to their original units to "stand by" after graduation. In this case, the state will call for going abroad as appropriate, provided that the police must join.
The United Nations peacekeeping force is a special cross-border force established in accordance with relevant United Nations resolutions. It was established at the time of the Suez crisis in 1956. Entrusted by the United Nations General Assembly or the Security Council, it is active in areas with international conflicts. Soldiers of peacekeeping forces wear sky-blue helmets or blue berets with the abbreviation of "UN" on them, and the armbands are decorated with the pattern of "Earth and Olive Branch". Anyone who participates in the United Nations peacekeeping forces must be sent to the training centers of the four Nordic countries for special training, familiarizing himself with the functions, objectives and tasks of the peacekeeping forces and conducting special military training.
