All of this data is collated and matched against client-employee information, GPS coordinates, detailed flight information for every aircraft that is part of an itinerary for each employee and a matrix of client operational rules and requirements.
The systems would allow a medic or corpsman treating a wounded warrior to record vital signs and other important information as well as request an emergency evacuation using precise GPS coordinates, starting with the first moments of life-saving care and making the information available using the existing tactical radio networks.
According to the patent, you could then be given directions based on GPS coordinates and the buildings "seen" by the watch, while a Goggles-like implementation would be able to identify smaller items in the display.
