Canadian Armoured Autocar

The Armoured Autocar was a Canadian armoured car used as a mobile machine gun nest during the First World War.
An individual Armoured Autocar carried 2 machine guns, 20,000 rounds of ammunition, extra gasoline and enough food for 14 NCOs and men. A Section was made up of 2 cars under the command of a Lieutenant, and a Battery consisted of 4 Sections under the command of a Captain. In addition to the armoured vehicles, each brigade also included a Section of motorcycles with 51 scouts who operated as signallers and dispatch riders.
The Armoured Autocars were to prove their worth in the German breakthrough of 1918. While Brutinel had envisioned the unit spearheading an advance through the enemy lines, they were to ultimately excel in the defensive role by utilizing their firepower and mobility. Unfortunately, the open tops of the cars left their crews vulnerable.
The Canadian Armoured Autocar is considered to have played a major role as an influence on later armoured car designs such as American Half-Tracks like the M2, M3 and M5 vehicles used by Allied Forces during the duration of the Second World War. Imperial German Forces also adopted the Sd.Kfz 251, along with the Russian BA-30. Armoured cars of the first world war are what most consider to be the predecessors to modern day light tanks, reconnaissance vehicles and armoured vehicles/armoured troop transports.
