Description: Kill enemy spartans with the Assault Rifle. This can only be obtained in War Games.
Tips: If your magazine runs out when firing on an enemy, switch to your secondary to finish them off. You won't get credit for the AR kill, but you won't have to wait through the long reload animation.
Level Kills XP Bonus
A total of 20,000 XP is awarded for completing the Assault Rifle Commendation.
