North Korea’s Tunnel Network Is Impressive (But Not Invulnerable)

A recent article [3] described a newly noted but apparently abandoned railroad tunnel in North Korea, located near Dancheon on the east coast roughly midway between Hamhung and Chongjin. It could be used for raising mushrooms (yes, seriously), document storage or military use – nobody really knows.
The lack of information regarding military usage cries out for discussion, for North Korea has used tunnels and other underground structures for a multitude of military and civil-defense purposes for decades.
