EMP Medal

The EMP medal is medal awarded in the Halo 3 campaign and Halo 3 ODST's campaign and firefight modes. It is awarded for removing a Brute, Jackal or Engineer shield with a Plasma pistol or a Power Drain, then quickly killing the opponent. It is represented by a 16-sided gold star with a green orb in the middle.

If done in Halo 3 ODST ten times in a single session, the My Clothes! achievement will unlock.
