'''Electromagnetic pulse''', or '''EMP''' is the electromagnetic radiation from an explosion (especially a nuclear explosion) or an intensely fluctuating magnetic field caused by Compton-recoil electrons and photoelectrons from photons scattered in the materials of the electronic or explosive device or in a surrounding medium. While organic tissue is unaffected, the resulting electric and magnetic fields may couple with electrical/electronic systems to produce damaging current and voltage surges. The effects are usually not noticeable beyond the blast radius unless the device is nuclear or specifically designed to produce an electromagnetic shockwave. An alternate definition is: a broadband, high-intensity, short-duration burst of electromagnetic energy. | '''Electromagnetic pulse''', or '''EMP''' is the electromagnetic radiation from an explosion (especially a nuclear explosion) or an intensely fluctuating magnetic field caused by Compton-recoil electrons and photoelectrons from photons scattered in the materials of the electronic or explosive device or in a surrounding medium.

*In ''Halo: Reach'' the [[M319 Individual Grenade Launcher]] has a secondary function that acts like an EMP. It awards a player an [[EMP Medal]] when it kills an enemy, being the only other weapon in the game that awards the medal. | *In ''Halo: Reach'' the [[M319 Individual Grenade Launcher]] has a secondary function that acts like an EMP.

*In ''Halo: Reach'', [[Armor lock|Armor Lock]] can trigger an EMP after use, which can take out a Spartan's shields. Combined with a quick and accurate melee, this can result in an almost instant kill. | *In ''Halo: Reach'', [[Armor lock|Armor Lock]] can trigger an EMP after use, which can take out a Spartan's shields.
