The Pummel medal (Bone Cracker in Halo 2, Beat Down in Halo 3 and Melee in Halo 4) is awarded for killing an opponent with a melee attack that does not assassinate him (a melee attack from behind). It is available in all Multiplayer gametypes and has a Bungie difficulty rating of 3 out of 10. 
It is represented by an inverted silver star with a dark green fist. After you kill an opponent with a melee attack, a message appears on your screen that says: "You beat down (player's name)". It is also awarded if a Covenant Energy Sword or Gravity Hammer is used to kill an opponent. In Halo: Reach, after killing an opponent with a melee attack, the message "You pummeled (player's name)" will appear.
- A common way for players to get the medal at the same time is to get a Double Beatdown.
- A simple method to earn this medal is to play Grifball.
