In the 2008 movie "Iron Man," the main character becomes a superhero after building a suit of armor with an exoskeleton that gives him incredible strength.
Today, elite U.S. special operations forces may be a few short years away from donning a similar suit, one that can monitor the user's vital signs, give him real-time battlefield information and be bulletproof from head to toe, the Associated Press reports. The suit might eventually have other features unheard of only a few years ago, including an exoskeleton made of liquid armor, smart fabrics that could help stop hemorrhaging, enhanced sensory capabilities and Google Glass-like visuals.
