X23 Non-Nuclear Electromagnetic Pulse Cannon

The X23 Non-Nuclear Electromagnetic Pulse Cannon (NNEMP) is an electromagnetic pulse weapon employed by the United Nations Space Command.

Design details
The X23 NNEMP consists of a turreted mount on top of the Gremlin vehicle. When fired, it emits a large electromagnetic pulse capable of knocking out vehicles and other electrical equipment.

Development history
The X23 NNEMP was developed by the Materials Group in the early stages of the Insurrection in the 25th century, designed to detonate weapons of mass destruction prior to detonation. This marked the first truly precise application of EMP technology, despite it having existed in some form since the 21st century. Following the outbreak of the Human-Covenant War, the X23 was leveraged to counter Covenant power generators and other important relaying stations during protracted battles. After it was found vehicles were sensitive to this particular EMP, the XRP12 Gremlin was made to support this weapon. Its special EMP ability is entirely ineffective against infantry.
