Cosworth’s Field Radio

Cosworth grips this compact radio in the cramped confines of UNIT Mobile HQ. Greyhound Seven first relays intel through its static: the Master reaches Stangmoor Prison in a black saloon car. The Brigadier then directs Cosworth to patch it through to missile control, readying remote detonation of the Master's nerve gas missile. Officers snap to action amid the device's persistent crackle.

Brigadier orders dual-pronged prison assault

Cosworth’s field radio is the lifeline between UNIT’s Mobile HQ and the front lines, its static-filled crackle the soundtrack to the operation’s pivotal moment. Greyhound Seven’s voice cuts through the interference, delivering the intelligence that sets the Brigadier’s plan in motion. The radio is more than a tool—it is the pulse of UNIT’s response, the medium through which urgency is transmitted and orders are relayed. Without it, the assault would lack the real-time intelligence necessary to adapt and strike with precision. Its role here is critical: the bridge between observation and action.

Before: In Cosworth’s hand, ready to receive updates from Greyhound Seven and other field units.

After: Still active, now serving as the command link for coordinating the dual-pronged assault on Stangmoor Prison.

Brigadier divides critical operations under pressure

Major Cosworth’s field radio is the lifeline connecting UNIT Mobile HQ to missile control, the critical link that will determine whether the nerve gas missile can be detonated remotely. As Cosworth grips the device and transmits ‘Trap One to missile control. Report my signal. Over,’ the radio crackles to life, its static-filled response a tangible reminder of the high stakes. The radio is not just a tool—it is the mechanism through which the Brigadier’s order to detonate will be executed, and its reliability is paramount. Without it, UNIT would lose its ability to neutralize the missile before it reaches its target, leaving London vulnerable to the Master’s attack.

Before: Functional and ready for use, positioned within reach of Major Cosworth in UNIT Mobile HQ. The radio is part of the standard equipment for field operations, but its role in this moment is elevated to mission-critical status.

After: Actively engaged in establishing a secure link with missile control. The radio is now the primary communication channel for the detonation sequence, with Cosworth monitoring it closely for any signs of interference or failure.
