Gunslinger-One is the callsign of a UH-60 Blackhawk in Call of Duty: Modern Warfare 2. It was only featured in the Special Ops mission, "Big Brother", where one of the players had to get to Nate's Restaurant whilst a secondary player placed supporting fire. It was equipped with an M61 Vulcan Cannon used to defend the ground soldier and extract said soldier at the end of the level.
