Ukrainian troops use a modified DJI Mavic 3 quadcopter drone to drop a mortar round into a group of Russian troops which results in multiple casualties.

It's impressive that the small drone has enough lift to carry such a hefty munition. While the blast may not look impressive, the kill radiuses significantly greater than what is seen in the video as deadly shrapnel is ejected in all directions. There appears to be at least two soldiers wounded, one seriously.
