The Army replaced its slogan, "An Army of One" with "Army Strong," but it may someday need to go back to it with development continuing on the XOS Exoskeleton. The weapon system is being created at Sarcos-Raytheon, a U.S. military facility in Utah and could just change the face of warfare forever.
It can walk, climb stairs and run with hydraulic components duplicating and augmenting the soldier's movements. While the XOS has a long way to go, it is not hard to imagine where the Army would like to take this: the Mobile Infantry power suits of "Starship Trooper" fame. Perhaps in a decade or so these suits could be tank, gunship, cannon and infantry platoon all rolled into one. If this technology was made to work than the Army would theoretically only need about 1,200 grunts instead of the 49,000 it currently fields.
