From TechCrunch:
Why we picked Ravn: The AR battlefield is inevitable, but right now Microsoft’s HoloLens team is focused on providing mid-fight information, like how many bullets a soldier has in their clip and where their squad mates are. Ravn’s tech was built by a guy who watched the tragic consequences of getting into those shootouts. He wants to help soldiers avoid or win these battles before they get dangerous, and his team includes an expert in selling hardened tech to the U.S. government.
