Flame Thrower Tank M67 (also known as M67 "Zippo", nicknamed after a popular brand of cigarette lighter) is a postwar medium flame tank that was designed in the United States. It was designed in the years 1952–1954 on the M48 tank chassis, at the initiative of the US Marine Corps. During the production, which lasted from 1955 to (according to various sources) 1956 or 1959, 109 M67 tanks were produced for the Marine Corps and US Army. The M67 was primarily used for mop-up style operations. The method of firing munitions was called "rods of flames". The swirling motion of the flames produced could reach round corners. The natural fear of being burned to death gave an added shock and awe factor to the M67.
