Except that to obtain a NLOS capability for the Spike, the weight was bumped up to 75kg. Which is almost impossible for it to be fired in the same manner like a Javelin (prone, sitting or from the shoulder).
And in the case of MMP, it wasn't that heavy, despite also having an NLOS capability as well as being launched from a tripod.
What I am stating here is that the new ATGM design suggest that designed to be fire almost exclusively from a tripod mode, the aiming system depicted does not allow for hand held operation like the Javelin does, it is more like the Kornet ATGM in that regard.
It might be that the PLA intended for the missile itself to be available in both conditions but requires the swapping out of the aiming systems to achieve that just like the Spike.
I do not see how the firing of a tripod precludes this system from being a man portable system.
If Spike variants like MR, or missiles like MMP which are both tripod launched, yet be considered man portable and compete with Javelin in the same competitions for man portable ATGMs, I'm not sure what the issue is.
If you are assuming that just because this system has a tripod it must be a certain weight, that is obviously not true because other systems like MMP exist with a weight that is only a few kg heavier than Javelin and is also man portable. And in the case of MMP, it also has a NLOS capability.
So let me summarize -- having a NLOS capability, and firing from a tripod, both tells us nothing about the weight of this missile, if you are concerned about weight and portability.
Once we have some specifications about the missile (one day, perhaps), then we will be able to make that judgement. But right now you're overreaching a bit.
