The sound comes from the announcer voice heard in Call of Duty: Black Ops II multiplayer, a game released in 2012. BO2 remained a fan favorite for its fast pacing and memorable online matches, and players began reusing announcer lines in montages, joke edits, and nostalgic posts. Over time, clips like this compilation spread through gaming communities as a shortcut for classic COD atmosphere. It is still used because the voice is immediately recognizable to many players and brings back the feel of competitive lobbies from that era.
