I read somewhere the claim there are more tubes (Artillery & Mortar) pointed at Seoul then in all of WWII. A factoid I find hard to believe, but I do believe an incredible number of rounds will fired toward Seoul before the tubes are silenced.
I have heard that statistic also.
it is true that incoming rounds can be electronically detected and tracked, that technology is very robust.
Using lasers to explode durable, rotating rounds mid-flight requires about four seconds for each round, it’s not just a single fempto-second laser pulse as some people are saying, here.
the Nork artillery barrage on Soeul would be like five clouds of locusts - total saturation. Using even our very best technology Seoul would be history.
we would prevail, sure, but Seoul would be history.
