Well, even the AFT-10 is significantly larger than normal ATGM. At 2500mm, it is larger than the Japanese Type 96 which is officially credited with +10km range and estimated to be capable of 25km.
This Jane's article says AFT-10 has a 43kg warhead. But since it is wrong on so many ways, AFT-10 definitely doesn't have a turbojet engine, I wouldn't put too much faith in about the warhead weight either. But a missile that size is likely to have a warhead far larger than is necessary to take out a tank, especially given it top attack profile. I think it is a good guess that AFT-10 is multipurpose missile rather than strictly ATGM.
The two longer ranged missiles are in the same class as Spike NLOS.
