Master's Cylinder Weapon (UNIT Lab)

The Master's cylinder weapon is the primary tool of his threat during the confrontation. He levels it at the Doctor, prepared to execute him, but the Doctor's threat to destroy the dematerialization circuit forces the Master to hesitate. The weapon shifts target to Jo Grant when the Doctor seizes the circuit, but her revelation of the RAF strike causes the Master to lower it and abandon his immediate plan. The cylinder weapon thus serves as a catalyst for the tense standoff, embodying the Master's ruthless intent and the Doctor's strategic counter.
