This strategy will only work when on the team without control of Command Post 5, preferably clones. DO NOT CLIMB UP THE ROOTS STICKING OUT OF THE CP! Instead, there is a small spiral path leading up it, easily found from CP6. Follow the path to the top, but stop before reaching it. As the enemy troops come down the trail towards you, eliminate them and remain there for MAJOR killstreak. You can easily get Frenzy, Gunslinger, and/or Regulator awards by doing this.
