Sharpshooter

Sharpshooter' is a spree medal awarded in Halo 3 Multiplayer for killing (without the necessity of consecutive headshots) 10 opponents in a row with the Sniper Rifle or Beam Rifle without dying. It is represented by a bronze five-pointed star with green crosshairs(much like the Battle Rifles crosshair when aimed at an enemies head). This is easier to get with the sniper rifle due to the more rapid rate of fire, more ammo capacity and more appearances throughout the many Halo maps.
