 Additionally, as part of their plan to modernize the country, the Koreans had invited the Japanese military attaché Lieutenant Horimoto Reizō to serve as an adviser in creating a modern army.A new military formation called the "Pyŏlgigun" ("Special Skills Force") was established, in which eighty to one hundred young men of the aristocracy were to be given Japanese military training.The following year, in January 1882, the government also reorganized the existing five-army garrison structure into the "Muwiyŏng" ("Palace Guards Garrison") and the "Changŏyŏng" ("Capital Guards Garrison").
