Carrington and Grey hijack the capsule

The UNIT low-loader serves as the primary vehicle for transporting the alien capsule. It is hijacked by Carrington and Grey during the ambush but is later reclaimed by the Doctor after he immobilizes the conspirators. The low-loader’s role as a mobile fortress for the capsule makes it a critical target for both sides, as control of the vehicle equates to control of the capsule itself.

Before: Driven by UNIT personnel, carrying the alien capsule, and part of the convoy en route to the Space Centre.

After: Driven by the Doctor, carrying the alien capsule, and heading back toward UNIT-controlled territory.
