The most common among the young soldiers was the Japanese army during World War II, that is, the young grass-roots officers corresponding to the senior Japanese officers at that time. At that time, there were many famous young soldiers who took military action privately to force their superiors to take military action. For example, at that time, the Japanese Kwantung Army invaded the whole Northeast, and the military action to avoid the Northeast Army was an action taken privately by the younger generation officer Ishihara Kwan-wan, who took risks when his superiors were drunk and succeeded by mistake.
