“MAARS” is basically a next-gen warbot that features a “M240B Medium Machine Gun…redesigned software… [and] mechanical range fan…to bolster safety by delineating live fire zones and keeping barrels pointed away from allied positions, respectively.”

A final precaution precludes the bots from firing directly at their control units — a feature that will provide little solace to the MAARS controller whose charge has just pulled a 180 after being hacked by enemy forces
