In "The Power of Three", UNIT is shown to have a scientific research department with a large laboratory in the base beneath the Tower of London. During the story, the laboratory is dedicated to studying cubes that appeared out of nowhere. Kate Stewart, daughter of the Brigadier and head of the scientific research department, has a handheld device that can scan a body (picking up the Eleventh Doctor's twin hearts), and also serves as a communication device. The computers at UNIT HQ can detect anomalies such as artron energy spikes, and can also access CCTV on the streets. There is also mention of them using helicopters and tanks while testing the destructibility of the cubes.
