I post this, not because it is good but it is typical Indian perspective and it is typically bad. Over all it shows that how Indian said leak of knowledge of PLA but it is very representative . I can break down by points.
Outdated information. China has not deployed any J-7including JJ-7, which was designed for training new pilots, near India at least 10 years. I don't know why this guy and a lot Indian "experts" in media keeps mentioning them. The most deployed fighter jets along the LAC is J-16 and this guy seems know nothing about this. He didn't even mention J-16. But instead, he was talking about Su-27sk which is the retirement process.
No idea about the existence of specialist aircrafts, such as AEW&C, reconnaissance aircrafts, EW aircrafts. One thing I found Indians really like to ignore is the existence of specialist aircrafts when they talking about air power balance between China and India. Because there are basically no reconnaissance aircrafts, EW aircrafts on Indian side and IAF has very few AEW&C.
No idea about the air defence chain on the ground. Another thing they like to ignore is China even without Air Force, it still has very solid air defence and radar chain along the LAC. On theatre level, it has HQ-9 and HQ-9B range around 200 KM. On brigade level, it has HQ-16, shot over 70 km. For field air defense and air defense while traveling, it has HQ-17. Then there are Man-Portable Air-Defence System for drones and lower targets. These things Indians usually just straight-out ignore because again they don't deploy much on their side.
Also the Indian side seems knows a little about "highlandsation" of Chinese equipments. So for a lot Chinese equipments, they were designed to fit the environment of 4000M, for example Z-8G, Z-10 and Type 15 tanks. All Chinese jets and transport aircrafts will have to do their test flight of adaptability of high attitude warfare. J-20, J-10, J-16, Y-9, Y-20 and J-11B all did it just to make sure there is little performance lost on high attitude airport, if they were given enough infrastructure support. I don't think Indian side know about this at all because they are still thinking whatever happen J-8 age, that jets need to sacrifice a lot just to take off .
As many other Indian "experts", this guy also don't read any first hand Chinese information, if you look though his tweet, this guy's Chinese military related news source is SCMP, I don't need to say more.
