The Canadian Automobile Machine Gun Brigade, also known as Brutinel's Brigade or the Brutinel Brigade, was the first fully mechanized unit of the British Army. It was established on September 2, 1914 in Ottawa, Canada, as Automobile Machine Gun Brigade No. 1 by Canadian Brigadier-General Raymond Brutinel, who initiated the program and was the unit's first commander. The unit played a significant part in halting the major German offensive of March 1918.
