DX Korea 2018 South Korean army ROK air defense and light tactical armored vehicles 

May I ask what part was breaking down all the time?

Maybe classified..

@@Choieunsok Yes , could be , This system is selected by the Indian army and is found much superior to the Russian Pantsir System . Maybe that's why it could be classified .

That's the whole point of SHORAD. Anything further is covered by Medium-range SAMs or Air Force jets.

@@kkachi95 wrong my friend i think Medium-range SAMs not very suitable for engaging low / slow flying objects I do not say that it is not able to shoot down low/ slow flying objects but i think it is not suitable for conducting such combat role , even if you review the kill probability for a Medium-range SAMs you can see the see the kill percentage of helicopters is lower than a faster highly maneuverable jet fighters with some noticeable difference .. at least they will waste the system payload of Medium-range guided ammo on secondary targets .. Medium-range SAMs intended to deal with jet combat aircrafts mostly low flying most deployments happen in the operational level , at the best behind the front lines , but not in the front lines or very close from it .. this ABC of the art of planning wars i.e included but not limited to dividing the combat zone , thedistribution and deployment of various forces and diversified weapon systems in the battlefield or theater of operations.. maybe i am wrong but this how i see the tactical and operational deployment and the combat employment of the Medium-range air defence systems ..

I'm not going to even try to make sense of your jumble of words, but data-link between low-altitude radars and medium-range SAMs are a thing these days and it's been integrated into South Korean air-defense network for years. Cheongung KM-SAM is designed exactly to do that. Welcome to the 21st century.

@@kkachi95 i know but you didnt understand what i meant , the integrated air defence network is more than 60 years old and not a 21 century discovering ,only the means and platforms or the elements of detection , searching , scanning had been expanding, diversifying, strengthening, along with reducing their sizes and increasing their operational efficiency. In parallel with the development and diversity of the communication means , the data links exchangers between these various elements has been developed and provided with faster and more efficient processors and the . so all wired, wireless, space-based communication modes linking and connecting , the diverse elements of the integrated air defence network have been developed ,evolved and improved with time ,anyway bare in mind the natures of the topography of S.Korea where your understanding or interpretation of the integrated air defence concept will be Collide with the nature of lands or the surrounding mountainous terrain and the limits enforced by the mountains barriers ..
