Second Gunman medal

Assist Riot (unconfirmed name) is a new multiplayer medal in Halo: Reach, first seen on a screenshot of the new Bungie.net medals page. It is awarded when a player gets 15 assists without dying, it is represented as a Running Riot! medal combined with the Assist medal. The medal's official name remains unconfirmed, however if Bungie's naming convention continues as it has done with the new Be the Bullet medal, then the final name is likely to be team/assist related.
