What Russia has Done
It is claimed that Russia has introduced a new Advanced Iranian Military Drone to the Ukrainian Battlefield, According to the Iranians, the Shahed-136 is extremely accurate; their videos show it hitting multiple targets with high precision. Such videos are easily faked, but the strikes at Abqaiq were notable for their consistent accuracy. The terminal guidance system is unknown, but may include some form of optical or infra-red imager able to recognize and lock on to targets rather than simple GPS guidance.
