This sound comes from Call of Duty: World at War, the 2008 WWII entry in the Call of Duty series. Online, players often label it as the Wehrmacht or German victory music, and it spread through uploads, montages and game meme compilations. It remains popular because World at War has a strong nostalgic following, and its faction-specific victory audio is instantly recognizable to longtime players. Creators still use it to give modern clips a classic Call of Duty tone and a clear sense of triumph.
