Storage Tank CO2 Fire Extinguisher
The Doctor grabs this CO2 fire extinguisher from the roof of a storage tank at the research complex and swings its metal body as an improvised club. He strikes Green Bromley squarely, dropping the lookout instantly in a swift ambush. The move buys precious seconds amid the chaos, as UNIT escorts scramble below. Bromley slumps unconscious, the extinguisher's weight turning safety gear into a decisive weapon.
