The flame thrower tank M67 (also known as M67 "Zippo",[1] nicknamed after a popular brand of cigarette lighter) is an American flame tank that was briefly used by the U.S. Army, and later by the U.S. Marine Corps during the Vietnam War.

Work on the design took place between 1952 and 1954, utilizing a modified M48 tank chassis, at the initiative of the US Marine Corps.

The "Zippo" featured no main cannon; the M48's 90mm gun was replaced with the tank's flamethrower.

[2] The natural fear of being burned alive gave an added shock factor to the M67.

The modern-day United States military has no flamethrower tanks in service.
