Protector medal

Protector is a Halo: Reach multiplayer medal. Appearing as a life ring with a yin-yang symbol in the center, the medal is awarded to a player who saves a teammate from death by killing the teammate's antagonist.

The Bungie weekly update in which it was revealed has a piece of text accompanying the medal, delving into detail on the mechanics:


 * " In Protector’s case, after a certain amount of damage has been done to a Player A by Player B, if Player C kills player B, he earns the Protector Medal. Player A receives a message (in the same place as messages like You sniped JimmyAwful) that says PlayerC saved your life. "
