I said “publicly shown” for a reason. As it stands, a better APS system has NOT been seen from China, nor has it been seen equipped online Chinese MBTs. The system on the ZTZ-99 isn’t even a proper hard kill APS. My point still stands. A proper, top-attack defending, hard kill APS is one of the hardest things to make, I wouldn’t be surprised if even China hasn’t successfully made one yet considering their lack of attention towards tank based doctrine. Speculation is not proof.
You can say China has a ton of hidden tech and maybe you’d be right, but that doesn’t count until it’s confirmed. By that metric I can say Pakistan has a dozen hidden technologies too, and nobody can prove me right or wrong.
