The sound comes from Tom Clancy's Rainbow Six Siege, the tactical shooter released by Ubisoft in 2015. Attacking operators throw small wheeled drones during the preparation phase to scout rooms, spot defenders, and mark objectives before entry. Clips of Siege gameplay spread widely on YouTube and Twitch, and players began isolating familiar in-game effects like this throw for edits and soundboards. It remains popular because drone work is such a defining part of every round, instantly understood by anyone who has watched or played R6.
