According to what I have learned, the assessment of the merits of peacekeeping forces is based on the specific situation and there is no fixed grade. Generally speaking, the meritorious service of peacekeeping troops is divided into several levels, such as first-class merit, second-class merit, third-class merit and honorary title, and the specific evaluation criteria involve many aspects such as the completion of the mission, the courage and dedication shown. Therefore, it is not possible to simply answer the question of "how many merits is the return of peacekeeping troops", and it needs to be analyzed on a case-by-case basis.
The peacekeeping force is a cross-border armed force dispatched by various countries, whose mission is to assist in maintaining regional peace and stability and preventing and resolving regional conflicts and disputes. Due to the complexity and diversity of peacekeeping missions, peacekeeping forces need to face various difficulties and challenges in carrying out their tasks, such as a hostile environment, complex political situations and humanitarian crises. In such circumstances, peacekeeping forces need to demonstrate a high degree of professionalism, courage and dedication in order to be able to accomplish their tasks.
Therefore, for the evaluation of the merits of peacekeeping troops, a number of factors need to be taken into account. Peacekeepers are likely to receive a higher rank of merit if they perform well in their missions, successfully complete their tasks, and show extraordinary courage and dedication in the face of difficulties and challenges. Conversely, if the peacekeepers perform mediocre or make mistakes, they may receive a lower merit rating or no credit at all.
In short, the evaluation of the merits of peacekeeping troops needs to be determined on a case-by-case basis, and it is impossible to simply answer the question of "how much merit does a peacekeeping force have returned?" At the same time, we should respect and thank the peacekeeping troops sent by various countries, which have made great contributions to the maintenance of regional peace and stability.
