People have just got it in their heads that armoured formations are over from the Ukraine experience without really critically drilling down to the root cause of why to see if that is a truly universal paradigm shift in armoured warfare, or just a Russian case special issue.
Yes it is the thinking that the small UAS(sUAS) [whether FPV or fiber optic] is the paradigm shift akin to the entry of the machinegun is not fully thinking this through. Just like the Machinegun in WW1 and trench warfare, the sUAS is the weapon that allows sides to remain statis. The sUAS (and a a well entrenched combined arms team) has allowed the smaller force (Ukraine) to prevent the larger force (RUS) from mounting any break throughs attacks. Russia it appears does not have the Operational capability or capacity to mount a break through of the Ukrainian defensive lines. sUAS work very well in the defense, but currently the sUAS is just a long range form if guided weapon.
Plawolf is correct in that the counter-UAS is not a mounted Platform (tank or IFV) requirement (meaning a requirement for a tank to engage and destroy the sUAS) but this is a formation requirement, so the formation moves under a protected posture.
Think about all of these uncoordinated counter-UAS defensive engagements trying to protect the individual platforms, that would lead to confusion.
The Tank requirement is for layering forms of defense (that others have talked about) that includes sUAS attacks from above. The PLA have APS for ATGMs. I don't want to advocate for the PLA, it is up to them to figure this out.
Bottom line is Plawolf is correct in IMHO.
Another point, the fallacy of inexpensive FPV sUAS is just false. They do not cost a couple hundred dollars. That is just hype, even with 3D printing and Chinese sources motors and controls. They are more in line to $1000 and when you add the cost of the attack payload the cost is much higher. I agree it is still cheaper that an ATGM, but they are not a couple of hundred dollars. Another factoid is optics, adding , outside of using Chinese parts of course.
Don't get me wrong in the current conflict there that provide constant surveillance and attack.
