Sonic emitter

The sonic emitter is a GDI weapon with unique defensive abilities, but consumes large amounts of power. It was developed basing on the harmonic resonance technology utilized in disruptors sometime between the end of the Firestorm Crisis and the beginning of the Third Tiberium War and originally used to dam the spread of and eventually dissolve Tiberium in Yellow Zones worldwide. Originally tools, they soon became one of the most important defense assets in GDI's arsenal.

The emitters are reasonably well armoured and consist of a massive support for a sonic emitter suspended on it. The emitter itself is shaped like a bulb. The turret unleashes a powerful sonic wave which rips through the battlefield and all units in its path, destroying or at least severely damaging them. It was brutally effective against the Scrin invaders during the defense of Stuttgart and the evacuation of GDI executives from Munich, carving a swath through their forces when engineers managed to reactivate the power grids. This was possibly due to the Scrin utilizing Tiberium on an unprecedented scale in their weaponry and technology.

The defence structure suffers from a low rate of fire (a requirement to keep it operational) and lack of precision when hitting mobile targets. As such, the Obelisk of Light, while less powerful, is much more precise and effective against moving targets.

Before 2047, GDI constructed mobile sonic emitters on hover platforms, codenamed Shatterers.
