UNIT’s failed contact attempt and capsule hijacking

Grey’s surveillance headphones are used to intercept UNIT’s radio transmissions, allowing Carrington and Grey to learn of the convoy’s route and timing. This critical piece of intelligence enables the conspirators to launch their ambush with precision, ensuring the hijacking is executed at the optimal moment. The headphones’ role in the event is purely informational, but their use is instrumental in the ambush’s success, as it allows Carrington and Grey to act with full knowledge of UNIT’s plans.

Before: Worn by Grey, tuned to UNIT’s radio frequency, and intercepting transmissions from the Brigadier and UNIT Control.

After: Still in Grey’s possession, but rendered useless as he is trapped by the Doctor’s anti-theft device. The headphones no longer provide an advantage, as the conspirators are unable to act on any new intelligence.
