The Canadian Automobile Machine Gun Brigade, also known as Brutinel's Brigade or the Brutinel Brigade, was the first fully motorized unit of the Canadian Expeditionary Force (CEF) during the First World War. It was established on August 24, 1914, in Ottawa, Ontario, 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 spring offensive of March 1918.
