(Modernized S-125

Only a handful of battalions of pre-modernization S-125s, the modernized ones are mainly for export.

S-200,

S-200 is only good for hitting B-52s and shit and they only have two regiments

Their S-300 knockoff, the KN-06

not operationally deployed

NK air defense trained their ass off, it's one of those service branches (Along with KPA SF, Artillery troops and Missile force) the North Korean would put every penny they have in to make it work, unlike the rest of the KPA that's rusting away.

false on two accounts, they haven't invested that much into modernizing ADN because the cost isn't worth it compared to simply using NBC weaponry and SF on ROK/US airfields. and "artillery troops" is dubious--they are still 99% at a 70s level for artillery.

North Korean artillery were also hidden in extensive tunnel network dug underground or under the mountains, designed to mitigate the effect of US munitions dropping on them and even to defeat bunker buster

their artillery revetments cannot defeat bunker busters, have you even thought about this on an economic basis?

S-200 are mostly deployed in defense of the capital Pyongyang. And while most of North Korea's SAMs are stationary, North Korea had made significant effort in modernizing its air defense grid. With mobile variant of the S-75 and S-125 on the table.

false on S-200s, half of them are not around Pyongyang

false on "significant efforts". they have not operationally deployed any mobile S-75s or S-125s.
