Technology needs support the small unit leadership, not overwhelm it, nor displace it.
You are also correct that leadership is over and above mere management. It's amazing how few recognize that fact.
We need technologists within our defense acquisition and R&D establishments who have infantry and armor and air support combat experience who are groomed for higher education and then lead development/acquisition efforts.
Need a strong dose of reality - and manual backups - to everything.
There is a similar system used in AH-64 aircraft with a monocle CRT attached to the helmet. There is a whole process to get it optimized prior to flight and requires alot of head movement to use while flying and maintaining SA since it only has a 40 degree FOV.
