Brigadier coordinates UNIT counterattack

The IE Factory Transmitter Controls emerge as the strategic prize in this exchange, with the Doctor pinpointing them as the 'key vulnerability' in the Cybermen's plan. The Brigadier's acceptance of this target—'Right'—marks the shift from debate to action. The transmitter controls are not just a physical location but a narrative fulcrum: their destruction could halt the Cybermen's doomsday bomb, making them the focus of the impending assault.
