This clip provided by the Ukrainian 1st Assault Battalion of the 92nd Brigade shows a Russian sniper being discovered by one of their drone operators. He is obviously unaware that he's been made, but finds out in short order as the drone drops munitions on him, destroying his legs. Viewer discretion is advised. There's a certain irony in a sniper being obliviously spotted and helplessly prosecuted from a distance at which he can't respond.
