IRA Terrorists Had Car Like Beltway Sniper
The Mazda used by the sniper squad was not only adapted as a firing platform, but it was, in the provocative language of one British newspaper, a “provo” tank.
It had been fitted with makeshift armor, to protect the sniper in case of return fire. The armor, stored in a concealed position, could be hoisted up behind the rear seats using a rope.
The sniper team also had another car, with a CB radio tuned to the same channel as the radio in the Mazda, presumably to be used as another spotting platform.
