“Yes. If need be, North Korean artillery near the DMZ could be accurately wiped out quickly enough to surprise the world.”
Do tell. How do you wipe out 20-30,000 targets that quickly?
Supposedly more tubes (artillery & heavy mortar) that can deliver more explosives that were delivered by artillery ordnance then WWII. All sighted in (or nearly so!), all that can fire pretty quickly some say within 20 minutes.
I have seen these factoids in several places and I do find them a bit hard to believe. However be sure a huge targeting problem if one wishes to save Seoul & minimize casualties.
