A grandfather of modern armored vehicles, the Armored Autocar was basically in a metal box atop the chassis of an Autocar.

20 Autocar trucks were supplied to Canada, of which 8 were Armoured Machine-Gun Carriers. They formed the "Automobile Machine Gun Brigade No. 1", which was deployed to Great Britain with the first Canadian contingent in October 1914. It stayed in Great Britain until 1916, among other reasons, because with the armies entrenching themselves, wheeled vehicles were deemed useless.
