In Yu Jing society those of Japanese ethnic origin are considered second rate citizens. Apart from this, the Nipponese social subgroup is highly hierarchized so the members of their lower classes have a very poor standard of living. For these people the best way to move up the social scale is to serve in the State Empire Army.
The army has regiments (Butai) consisting exclusively of Nipponese, both from the Japanese islands on the Earth, and from Kuraimori, in Shentang. The troops than make up these regiments are called Keisotsu, which in Japanese is a title of the greatest honor meaning Excellent soldier. However, the State Empire Army uses the Keisotsu Butai in the front line, where the action is always dangerous and the mortality rate very high. Although it hasn’t been confirmed by the Party, the figures for the average life expectancy of the Keisotsu recruits sent to a “hot” area are chillingly low. The danger, however, has its reward: the honor to serve the State Empire and the social improvement for those who prove their courage and commitment.
