True.
But there isn't stuff there that I have not read before.
I remember reading about American advisers coming to Taiwan to evaluate the ROCAF modernization. Their comments were in effect, that despite all the new hardware coming in, their software has not come to match. On the other hand, on the other side of the straits, the PLAAF has been upgrading their software to match their hardware.
By "software" that means training, organization, doctrines, etc,.
That time, ROCAF had its problems. It has problems keeping pilots in the airforce, because the civil airliner business pays much better. (The JASDF had this problem too, so its not just a local phenomenon, and so I wonder to what extent S. Korea and even mainland China has this phenomenon. Quite likely too I would think, because the PLA as a whole has been complaining about their salaries.) At one point, the ROCAF had more modern fighters (IDF+F-16+M2000) combined than pilots to fly them.
That was years ago though. Hard to say if the situation still exists now.
I do think that in my opinion, the ROCAF "slept". They did not take the PLAAF modernization efforts seriously until it was too late. They had the attitude that the PLAAF was technologically inferior, that they could not even operate their Su-27s properly. I'm sure they love those stories about those Su-27s either falling out of the sky or not getting off the ground at all. Its not as if the PLAAF didn't have their modernization problems, they did, and there was plenty. But they also seemed very determined to get through that hump and had a lot of resources to match that determination.
For a long time, even with technical parity on the aircraft, and against superior numbers, the ROCAF pilots for a long time were better trained, an assumption which is not unjustified, considering the record and standings of ROCAF F-16 pilots in Luke AFB, which has competitions among different F-16 pilots around the world.
But arrogance leads to complecency until it is too late. The PLAAF, by keeping its modernization close to its chest, also helped kept those alarms from sounding off.
