The technology is not new (Score 1)

The military have used this technology for quite some time in vehicles, connecting a GPS to a military radio, which will transmit coordinates back to observers. Earlier this week my unit trained in a war-simulator, where the GPS-unit was sewn into the clothes, transmitting coordinates, ammunition-usage etc back to observers, who could then watch the operation in real-time in 2D-maps, aerial photos, or computer-generated 3D-landscapes.

They showed us the observers-room, and replayed the whole game we played later. It was incredible awsome :) I guess(/know) other countries military forces have the same kind of technology and simulators.
