A four-legged Chinese robot that looks like Boston Dynamics’ Spot has gone viral again on Twitter and Reddit, but this time a couple of new features appeared. According to a new video, the machine can be transported using a drone. And most importantly, the robot has a mount for weapons.

Before reaching social media, the video was uploaded to the Weibo page of China Kestrel Defense which contains the English words Blood-Wing in the upper right corner. As noted by The Drive, it is unclear what Blood-Wing means, but it’s certainly eye-catching.

The drone, which Kestrel calls Red Wing, can move behind enemy lines and launch a surprise attack by dropping the robot dog, the defense company said.

War dogs descending from the sky, air assault, Red Wing Forward heavy-duty drones deliver combat robot dogs, which can be directly inserted into the weak link behind the enemy to launch a surprise attack or can be placed on the roof of the enemy to occupy the commanding heights to suppress firepower,” says the caption of the video.And ground troops conduct a three-dimensional pincer attack on the enemy in the building“.

Chinese robots often go viral on social media, but if they used to wear silly little hats and dance in unison, today they took a darker path. And with new Cold War tensions rising — with the US and its allies on one side and Russia, China and Iran on the other, it’s easy to see why videos of deadly robots are getting attention.

Boston Dynamics, of course, is the name most closely associated with a potential robot uprising in America, given that Atlas can do backflips and is quite nimble. But Boston Dynamics is not the kind of company that creates tomorrow’s killer robots for American soldiers. Last week it promised not to make deadly robots.
