I don't buy it, judging by both the pictures and the video. This new ATGM is designed to be fired from a tripod (i.e: fixed position) which means that needs to be set up pre firing. Compare that to a Javelin or a HJ-12, which only needs the operator to attach the CLU to the missile tube and it ready to go. Weight wise it is likely going to be heavier than the Javelin.
There is a difference between a ATGM designed to be used by foot soldiers and ATGM that are designed to be man portable. The former is intended to be used by soldier on the ground in mobile squads where the option of "hiding behind a mountain" and shooting a ATGM is neither practical or optional all the time. In that scenario getting into line of sight with a tank is more or less acceptable because :
1) There is no way of ensuring soldiers have consistent access to the luxury of long range detection systems like drones
2) You are most likely to stumble upon enemy armor unexpected which means the other side won't be expecting you either so there is the exploitable element of surprise and terrain. It takes a well trained tank crew to detect and locate a ATGM firing and then decide whether they want to run, fire a smoke screen or fire back.
If line of sight is something that is so deadly then weapons like the PF-89 and it's successor units would have been discontinued long ago.
Missiles like MMP and Spike are also designed to be fired from a tripod, however they are still considered to be man-portable. There is a reason why the likes of MMP and Spike and Javelin often compete for the same ATGM competitions and tenders.
The combined weight of MMP is 15kg (missile in tube) and 11kg (tripod and launch unit) for 26 kg total.
The combined weight of the equivalent range Spike MR is 13kg (missile in tube) and 13kg (tripod and launch unit) for 26 kg total.
The combined weight of Javelin is 15.9kg (missile in tube) and 6.4kg (launch unit) for 22.3 kg total.
Javelin is slightly lighter than both of those systems yes, but you still ultimately need to set up all of these systems as well.
The extra step of having a tripod as part of the launch unit for MMP or Spike does not mean they aren't "man portable", and there are only a few types of terrain where a Javelin can be fired that MMP and Spike cannot.
In any case, this new PLA ATGM clearly isn't intended only for NLOS use -- if it functions anything similar to MMP, it will be capable of both NLOS and line of sight engagements.
Basically, I don't see anything that Insignius wrote which is incorrect -- this is essentially a slightly larger, longer ranged Javelin type ATGM with NLOS and offboard targeting capability added in addition to standard/traditional line of sight engagement capability.
