Again the same for 现代级 and 现代级II. You also don't know what kind of upgrades that PRC did to 现代级 after Russia sent them there.
数字化部队 also is the most popular topic for PRC military. One of the prime reasons for cutting people from military and increasing GDP spending on military.
You think the first wave of missles would fly along? By the time first wave of missles hit ROC, there will be accompanied by first wave of jet fighters specifically targeting landing strips and other important air force structures and would come as a surprise attack. So it is not that simple like you said to wait out after 6 waves of missles hit. ROC radar experts said the radar response time from any sudden PRC missle and air attacks is only a few minutes so not enough time to prepare any defense. Plus, in 4 hours of missle strikes on air strips any people would dare to go out on the air strips to repair them? 机动的地空导弹、雷达都不会跑吗? how powerful are those mobile radars? Definitely not as powerful as those building size radars right? What do you think anti-radiation missles are for? 战机不会转场到东部机场躲入山中坑道中吗? Of course you can and of course PRC has very good spy satellites that knows where you underground bases are. Collaspe the entrances then all your 战机 would be buried inside mountains. What do you think high accuracy cruise missles are for?
Also you should know, by the time PRC army lands on ROC, they would sure to have both air and sea superiority. Any 雷霆两千 would come under air and sea attacks as PRC would carpet bomb all the landing points and make sure any nearby structures that were pointed upwards become flat before landing its army. That doesn't count any air landings or any special forces.
One last thing, don't underestimate the chance that PRC use small and clean nuclear arsenals against tough spots such as the small neutron bomb.
There are just too many tactics that PRC can use on ROC. Even your government listed 7 ways that PRC can attack ROC. Nothing is preventing the PRC use 2 or 3 ways together or all 7 at the same time.
Also, please stop thinking superior weapons will win and inferior weapons will lose.
As I said in the past and I say again, in the end, the side that suffers and loses the most in this war is not the PRC or Japan or US, but the people of ROC.
