The story says the project intends to “increase lethality by enhancing the ability to detect, decide and engage before the enemy”
So I would guess feeding information from scout and observer drones and other types of sensors to the soldiers so they can more effectively see camouflaged or hidden enemy positions, be more quickly aware of enemy movements, etc.
I can't imagine fighters using the existing version for an extended period of time while engaged as some sort of AR tool (see around corners etc.). However, maybe they'll produce a "military spec" version that does just that. Maybe they will be able to toggle on/off like night vision to reduce fatigue.
