So far, North Korean soldiers stationed near the border are reportedly selected from families known to be most loyal to the communist regime to try to prevent military defections that may embarrass North Korea. Moreover, in order to look stronger, soldiers who are at least 170cm tall are stationed. However, nowadays, soldiers who are tall enough and from a loyal family are very difficult to find. Due to the chronic food shortages, many soldiers are malnourished and very short. They now place just tall soldiers even if they are not from a loyal family. From this we can infer the gravity of the food shortage in North Korea.
