The Energy Dissipator special weapon of the game Star Trek: Armada dies exactly what the name suggests, draining the targeted ships of their special weapon energy. It is researched at the Gre'thor Armory. When used, it automatically picks four targets of the surrounding opposing ships. Their special energy is being drained steadily (not all at once). It looks like this:

The Energy Dissipator also targets cloaked ships, decloaking them on impact.

An active Corbomite Reflector has no effect on this special weapon. Neither does the Shield Remodulation. The Phase Cloak will protect against it.
