This is a step up and
Seems like what they are doing here is to adopt a two system scheme. The helmet mounted system for navigation and tasks well the rifle is for fighting. It makes sense. But there is the trade off.
Well the helmet NGV is down over the eye the soldier can’t use the rifle Sight effectively. Now if you are laying an ambush this isn’t a problem you are probably prone and switching to the rifle sight. But in navigation you don’t know when you might encounter hostiles.
Infantry combat in the modern era happens when two infantry forces run into each other.
This is where a third piece of kit shown at the parade comes into play.
The vertical foregrip/Bipod/laser/Illuminator. These rifles are fitted on the 6 O’clock rail with a vertical grip that grip has 3 buttons, a bipod, and a laser warning decal.
the laser allows the shooter to have a general idea where the rifle is pointing and can be operated in IR mode. This would mean that only someone wearing NGV that see in the near IR spectrum can see the laser. Allowing the soldier to navigate however. There is the rub.
Against other modern infantry Wearing NGV the laser and it would point back to the soldier’s position.
As such against poorer countries it’s okay against more modern it’s a problem.
Now there are a couple possible work arounds.
The first is the simplest turn off the laser. Use the rifle scope if you are moving about. That’s fine for some movement. But some jobs that is going to be awkward. Fine for room clearing not so for driving a truck.
being blunt though having only a monocular means loss of depth perception anyway.
Second would be to try and stream the video from the rifle scope to the NGV. That’s complex and the closest that they seem to have come on that is the QST-11 which seems to be China’s land warrior gun. This would also in theory allow shooting around corners.
These systems seem to indicate that that is not a capability meant for general issue just yet.
