The theme comes from Call of Duty: Modern Warfare 3, the 2011 shooter in which multiplayer matches pitted factions against each other, with PMC as one side. A short victory sting played at the end of a winning match, giving that faction its own musical signature. Clips of the sting later circulated on soundboards and in gameplay edits, where editors reused it outside the game as a generic signal for winning. It endures because it is instantly recognisable to players and instantly readable to anyone else as a win.
