This particular robot from HDT Robotics (hence its name) is ready to open fire an M240 machine gun at a target 150 meters away at your beck and call, and there were also other robots from notable names such as Northrop Grumman, 5D Robotics, iRobot, QinetiQ and Lockheed Martin being paraded, although not all of them would be harbingers of death, but rather, to demonstrate how they are able to maneuver through rough or wooded terrain, carry heavy loads and move autonomously. Will a robot be able to replace a human soldier on the battlefield eventually one of these day? We shall see, as time is always the great teacher. After all, robots never fatigue, and the loss of them would be more or less strictly monetary with no compensation to be paid out.
