|“||The Ion disruption field generators are preventing a potential strike from GDI's Ion cannon. Eliminate them!
- EVA, Siege of Temple Prime
The Ion disruption field generators were Nod defensive structures designed to prevent ion cannon strikes on a designated area. Three of these generators were deployed during the Third Tiberium War at Temple Prime. Together, they generate a force field that shields a large area around Temple Prime from ion cannon strikes. If a generator goes offline, the force field's effective area becomes smaller.
Data on the Temple Prime generators were leaked to GDI by Nod Abbess Alexa Kovacs and AI LEGION in an attempt to discredit General Kilian Qatar before Kane. The generators were subsequently targeted and destroyed by GDI during the siege. This allowed GDI Acting Director Redmond Boyle to order an ion cannon strike on the complex, detonating the Liquid Tiberium Bomb, and luring the Scrin to Earth.
