The Raytheon second generation Exoskeleton (XOS 2) makes any wearer a real life 'Iron Man'.

Developed by Salt Lake City based Raytheon Sarcos, the suit was designed to be used by the US military to allow one soldier to do the work of two or three, lifting heavy munitions, with an eye one day on bringing a field version for infantry into action.
