Knife to a Gun Fight is an achievement in Halo: Reach. It is unlocked when a player, playing as an Elite, kills five Spartan players in Invasion on the Elite side or in Firefight Matchmaking.[1]


  • The achievement's name refers to the phrase "Don't bring a knife to a gun fight," which means that you shouldn't enter a challenging situation without being properly prepared or equipped.
  • The name could also be a reference to the Energy Sword, which is the primary weapon of most Elites, while Spartans mostly use guns.
