Electromagnetic Pulse cannon

An EMP Cannon, or electromagnetic pulse device, was utilized by both GDI and Nod. It was capable of shutting down any vehicle or structure by disabling it's electronics. The EMP weapons were fairly widespread in the Second Tiberium War, as the technology was reliable and inexpensive. A mobile version, the Mobile EMP, was developed to provide close support for frontline units.

The cannon consisted of a large device mounted on a turret which concentrated and stored a significant amount of energy in a spherical shell, which it could launch at long distances. Once it detonated upon impact, a wave of energy spread out linearly from the impact site, creating a circle of moving charge that flooded the systems of a vehicle. Fortunately, most vehicles were reasonably shielded against such effects, and thus no permanent damage was normally done, but the charge still had to be cleared from the system - in the meantime nothing would work. The EMP device could disable all vehicles, structures, and cyborgs in its area of effect, including the cyborg commando.

The only documented case of EMP cannon usage was by Cabal. As part of his ferocious defense of his western flank, he used an EMP cannon, followed by an ambush of cyborgs. However, Nod forces were still able to move past Cabal's defenses, eventually capturing 3 of his codes and helping to bring down his Firestorm Defenses.

It should be noted that despite the vast amount of electrical systems present on board the Core Defender, Cabal managed to block the effects of EMP devices against his Core Defender.

After the firestorm Crisis, the reliability and effectiveness of the EMP have prompted GDI to estabilish EMP Control Centers in major Yellow zone cities to allow the dwellers to buy some time to evacuate.
