This line comes from Metal Gear Solid 2: Sons of Liberty, the 2001 stealth game from Konami starring Solid Snake. In the game, Snake's calm, understated delivery fits his experienced soldier character, and the short praise has since been lifted from gameplay into soundboards and editing libraries. As clips of precise shots and lucky hits spread on video platforms, creators began using it as a quick reaction to skillful play. Its brevity and recognisable voice keep it useful long after the game's release.
