The Bulltrue medal is a Halo 3, Halo: Reach, Halo 4 and Halo 5: Guardians multiplayer medal that is awarded when a player kills another player who is in the act of an Energy Sword attack. The lunge does not have to be directed at the player who makes the kill. The medal is represented by a brown diamond with a silver outline and a bull's head with golden horns in the center. Upon execution, the medal is accompanied with the message, "Bulltrue!"
