This is why I really wonder just how much ammunition the DPRK military even have. They may not have enough to last one day of combat! Much has been said about how the Norks have enough artillery aimed at Seoul to level it. This makes me wonder how many of those supposed artillery units actually still exist, how many of those which still exist can actually still fire, how much ammo they have, and what condition that ammo is actually in.
A few years ago during a period of elevated tension the Norks had a live fire artillery exercise on a border island intended to intimidate the South. Half the rounds were duds.
