Future Soldiers May Be Wearing 'Iron Man' Suits

Salt Lake City, Utah (CNN) -- A lunchtime crowd is gathering beside the parking lot at Raytheon Sarcos, the defense contractor, on a recent day in Salt Lake City. White-collar workers from nearby office parks stand with their yogurt cups and sandwiches, watching with quiet awe as a man in a metal suit -- sort of half-man, half-robot -- performs superhuman feats of strength.
This may be the closest these people will get to a real-life "Iron Man," the character from the comic books and hit movies.
Inside a prosthetic shell of metal and hydraulics, Raytheon test engineer Rex Jameson is putting an XOS-2 exoskeleton through its paces.
As the crowd watches, Jameson uses his robot hydraulic arm to shadowbox, break three inches of pine boards and toss around 72-pound ammunition cases like a bored contestant on the "World's Strongest Man."
