Cutting Crew

Cutting Crew 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 kills with a Energy Sword without dying, it is represented as a Running Riot! medal with an Energy Sword in the middle.

Trivia

 * Since you need 15 kills with the Sword, it is likely this medal can only be unlocked in a Swords version of a gametype.
