The Ronson system was a flamethrower for vehicle mounting developed in World War II and used by the Canadian Army and the United States Marine Corps. The Ronson was developed by the British Petroleum Warfare Department in 1940. Having insufficient range it was passed over for British use but taken up by the Canadians for further work. The Ronson was developed in time sufficiently to be used for production of the "Wasp MkIIC" flamethrower variant of the Universal Carrier.
