Doctor intercepts robot ambush at bunker

The Doctor spots an active machine gun turret above the bunker entrance moments before it opens fire, forcing UNIT forces to take cover. Recognizing it as an automated defense system, he warns the Brigadier, averting disaster. A tense standoff unfolds as UNIT adapts to a new threat—one that blurs human culpability, framing the Scientific Reform Society’s technological sabotage as a decisive escalation in their bid for control. This confrontation tests UNIT’s readiness against insidious, unseen antagonists manipulating their environment.
