I worked the command center communications bunker at Yong Son for a year.
Each time we had “war games”, within about a minute of the games official start we’d get a message to shut down operations as we’d just been hit with a (whatever) megaton nuclear weapon.
If war were to break out on the Korean peninsula it will not be pretty. Both sides are very very well trained.
I’ve read that NK has enough short range bio and chem missles to wipe out Seoul. Man I wouldn’t want to be anywheres near that place if **it hit the fan.
