Usually this is achieved by mounting cameras on the vehicle with the images projected inside the tank, but with the HoloLens, it will make it easier. Created by Limpid Armor, the HoloLens-enabled helmet will be dubbed the Circular Review System. The video feeds that are gathered from the cameras outside of the tank will then be stitched together and sent to the headset, thus allowing the wearer to see around the vehicle.
Not only will this allow them to have a better view, but apparently the helmet will also let the wearer tag enemy and friendly soldiers, and also designate targets and send information back to the commander. The helmet has yet to be field tested and was recently shown off at the Arms and Security show in Kiev last month, but its potential has been noted by the Ukrainian military who might have plans to put them to use in real-life situations.
