A Chinese military contractor created a video showing off its terrifying new military technology, revealing a robot attack dog that can be dropped off by a drone.

The video that was initially released on the verified Weibo account of “Kestrel Defense Blood-Wing,” a page affiliated with a Chinese defense contractor, shows a drone hovering over a building and then dropping off a robot on the roof. After the drone flies away, the robot gets up on four legs and then begins to scan for targets around the building with what appears to be some sort of automatic weapons attached to its back.
