Wired.com said:The XOS 2 is an upgrade to the original XOS built for military use by contractor Raytheon. It is lighter, faster and uses half the power of the XOS, and – according to one of the uninjured test-soldiers – lets you press 200-pounds or do pushups with 150-pounds on your back without even feeling it.
While the suit is clearly perfect for fighting, when it makes it into service in five years it will be used just like Ripley’s power-loader in the movie Aliens. A tethered, full-body XOS would be used for loading weapons and supplies (and, of course, fighting Alien queens in airlocks). A pants- only version, encircling legs and waist, could be used in the field to help troops carry heavy loads.
The Raytheon XOS 2 was named one of TIME magazine's 50 Best Inventions of the Year, apparently allowing "even its least muscular wearer to lift 90kg (198 pound) loads."
