It is not Iron Man. It isn’t even Iron Fist. Lockheed Martin’s newest exoskeleton is more like Iron Leg. But for a soldier humping his weapons, ammo and body armor up a mountain in Afghanistan or a high-rise building in a future urban battle, a device to take the load off would be welcome. And, unlike science fiction supersuits, we can build it now.
Exoskeletons are part of the Pentagon’s Third Offset Strategy, which seeks to use robotics and artificial intelligence to enhance humans on the battlefield, rather than to replace them. There’s no area where the need is more acute than in the infantry, which takes the vast majority of casualties.
