Behind the killer robots of Ukraine's new warfare 'revolution'

A military mechanic with the call sign Chimera watches his fellow soldiers prepare new vehicles for field use in a workshop in the Kharkiv region, Ukraine. KHARKIV REGION, Ukraine - In a cramped workshop near the front line in northeastern Ukraine, military mechanic "Chimera" is helping prepare his unit's robot forces for battle. Lined up in a row, the four-wheeled unmanned vehicles known as "Hyenas" will crawl toward Russian lines with their payload of explosives and attack an enemy dugout or halt an advance. Similar models have captured Russian prisoners, said Chimera, 44, who asked to be identified by his call sign. In a time of both misinformation and too much information, quality journalism is more crucial than ever.
