It's said to be YJ-18
That's what I proposed over on CDF as well.
But do you have a source? I personally thiink it's YJ-18 because it definitely isn't CX-1 but it is also definitely an AShM, and it's not YJ-12 or YJ-62 either...
Nope
I have a video link here of the segment showing launch and supposed impact from 1:38 to 1:46
screen capture:
A model of trust mounted launch containers. If anyone knows the dimensions of the truck (especially the distance from just behind the front wheels to the last set of wheels), then we may arrive at a good estimate of the length of the missile.
Or you can use the rocket to estimate if you know what type they are, assume they are placed more or less parallel to the cx-1 model.
