X23 Non-Nuclear Electromagnetic Pulse Cannon

The X23 NNEMP Cannon is a weapon in service with the UNSC Marine Corps. It was designed by the Materials Group of the Office of Naval Intelligence to knock down Covenant power generators and other important relaying stations during protracted battles. After it was found vehicles were sensitive to this particular EMP, the Gremlin was made to support this weapon. Its special EMP ability is entirely ineffective against infantry.
