This sound is associated with Age of Empires II, the classic real-time strategy game released in 1999. Short voice clips and unit noises from AoE2 have stayed memorable because of the game's huge long-term player base and years of online matches, streams, and memes. Sounds like this one spread through gaming communities as quick reaction audio, especially in retro PC edits and strategy jokes. It still gets reused because even a tiny clip can instantly signal nostalgic RTS energy to viewers who recognize the game.
