Super Intelligent Robots #2

When the team returned to Washington, the robot was evaluated by expert scientists and determined that it was, what the colonel suspected, a super intelligent robot. In order to fully understand the functions of this robot, experts propose turning on said robot. The decision was made by Washington to turn on the machine. In doing so the U.S. sealed its own faith. The super robot escapes the installation and started to kill humans left and right. Panicked, the government sends the entire military, all 4 branches, to respond to this crisis. One super intelligent robot vs. the entire United States military.... Despite the fire power and advance weaponry, the United States was unable to stop this creature and 90 percent of humans making up the military were killed or severely wounded. Only those soldiers that didn't engage the enemy survived. At the end, the robot stopped its bloodshed from a very unlikely source, a voice in its head. This voice instructed the robot to stop and return home.
