You've seen it in ever war movie ever: soldiers trying desperately to get in touch with command. Well soon they'll hardly have to phone home at all, at least if DARPA has any say in it. They'll get all their data the same way pirates do. Torrents, basically.
DARPA—makers of mind-controlled prosthetics and creepy robots—just completed a field test of technology called the Content-Based Mobile Edge Networking (CBMEM) that lets soldiers sync battlefield intel peer-to-peer, like seeders and leechers in a torrent network, or maybe even more accurately, like different computers using BitTorrent Sync. With the software loaded onto Android phones and other battlefield software, separate teams are able to get the same picture of the situation without having to phone home for an explainer.
