A robot, equipped with an M240 machine gun, moves through the darkness until it stops under a stand of trees 100 yards from its squad of U.S. troops. The robot uses thermal imaging to detect enemy combatants hiding up ahead and aims its gun at them.
In a base perimeter mode these make a lot of sense. Reminds me of the autoguns from Aliens, but now with tracks. I figure we are just a few decades away now from seeing full robot on robot conflict as our troops move to a coordination role rather than taking the front line positions.
