The Carl Gustaf M4 has previously been shown, and is now fielded by the US, with the Aimpoint Fire Control Unit:

Now Senop has come out with a similar 'smart scope' but that adds thermal imaging capability, all while weighing 1.5kg.

Being able to use the CG at night with a FCU seems a worthy upgrade.

Ideally the next iteration will be a FCU with electronic trigger linkage ala Tracking Point / SMASH 2000. This would allow the CG to 'lock on' to a moving target, then automatically fire when the sight determines that the round would be able to hit the moving target. 

Such a sight would allow near guided projectile level of hit probability at a fraction of the munition cost - I'm surprised it dosnt exist already. 

Maybe they're working on the tracking system even as we post?

Using the Carl Gustaf at night seems a bit like putting up a big neon sign at the gunner's position that says... 

HEY, ENEMY GUYS.  HERE I AM.  PLEASE SHOOT ME.

Confined spaces munitions would have a smaller visual report?

Against a modern force with night vision and especially thermal equipment, I'm curious how much traditional things like muzzle flash will matter? 

Under thermal, even a basic rifle firing with a suppressor that eliminates visible muzzle flash will begin to glow like a beacon:

Hopefully, it seems like the most useful application for such a system (far more useful then a smart scope for a rifle).

I may be wrong, but it seems to me that one of these might be a bit more noticeable than the other.

The 84mm is not really that noticeable at night. Sure, there is a little flash, but not as extreme as in the photos, as the camera use high ISO, long shutter-time, wide "light opening" or a combination of those, to be able to take such a picture at all.

The 84mm is actually more noticeable in the day, as it creates a noticeable cloud of dust when firing.

Still, it is not a good idea to shoot it standing up or kneeling, when you should be prone.

No, it is not very pleasant to fire it, but really not that bad either, and you get a nice, warm, fuzzy feeling inside of you. And even more so for the loader, being much closer to the nozzle and the back-blast.

Thanks for the correction.  https://youtu.be/C8eySsr9wo4?t=30
