Re: Marketing rubbish
The fact that future soldier failed has NOTHING to do with the viability of a remote view gunsight - the goals for that were way higher.
This is not a hard problem to solve. All the tech needed has already been developed by to the extreme sports / home security camera industry.
We now have ruggedized, high framerate, high resolution cameras with IRNV capability readily available - surely all you need to do is place one of these behind a conventional sight and you have a remote sight?
If you used something like a reflex sight that was relatively unaffected by eye position, then you have a ton of tolerance, so could probably just attach a wireless barrel cam with pipe clips and it would be fine.
If you did it in this form-factor, it would be simple to retro-fit to existing weapons and also mean the camera would serve other uses apart from a remote sight:
General purpose periscope
Combine it with a collapsible pole (like a quickpod) to be able to easily look over walls, under cars etc.
Repurpose the "capture on motion" functionality of the action cam to also send an audio alert to the operator. Camera could be left watching the squads back, and they get an alert if anything moves and they can watch the recording of what moved.
If you could get a cam within earshot of enemy troops, you may be able to gather valuable intel.
A lot of security cams provide two-way audio, there would probably be many ways of re-purposing this. For example, you could trick the enemy into thinking you were one place by sending audio to a remote cam.
Yeah the military generally ruggedizes stuff more than commercial gear, but action cams are widely in use by troops already (as personal items) so they are clearly close enough - by the very nature of their use you would want them to be plentiful (Each soldier would probably want 2 or 3), so I fail to really see what the problem is. I guess it is more a case that the military would rather not have loads of cameras floating around on the battlefield, for PR / Security reasons.
