Microsoft HoloLens finds second home in the military after failing battlefield tests Let’s hope air cargo checks don’t trigger the same headaches The US Army's attempt to turn Microsoft HoloLens headsets into battlefield kit may have failed, but the AR goggles aren't going into the garbage. Instead, they're being repurposed for remote cargo inspection support.…
