A soldier's natural home is on the battlefield. So what happens when to infantry when conflicts move online? It turns out that DARPA, America's mad science division, has a solution called "Plan X." The project is designed to make cyber-weapons as easy to use as a pistol, but also to use technology to turn soldiers into digital warriors. One of the more realistic aspects of the project is to equip marines with hardware that'll sniff out wireless networks that could be hosting booby traps.
