Ion cannon uplink upgrade

The plug in module used by GDI commanders and forward bases to gain command and control of the Orbital Ion cannon, though it should be noted this is contradicted in the first Single player mission of the FPS CnC Renegade, where the Ion cannon independantly charged and fired on a Nod installation, that would have no doubt possesed a comms centre further confusing many, as usually the Ion cannon required a beacon to fire in Renegade. But this has been justified as a balance issue, and also, in the new Tiberium Wars, the Ion cannon was actually seen in one cut scene Targetting and destroying inbound Scrin ships,and WITHOUT the Philadelphia assisting its own targeting procedures. but it could be explained as purely conditional, as well as certain conditions can allow for such Ion cannon engagments
