The Russian Empire was the first country in the world which officially accepted armoured cars for service. It happened in 1908 when the Russian army received ten armoured cars built by the French company Charron, Girardot et Voigt designed under the project of a Russian officer M. Nakashidze.
"Nakashidze-Charron" armoured car.
"Russo-Balt Type C".
The vehicle got a very positive feedback from the military men, however, the pre-war development of armoured forces was over at that. One of the main reasons for that was a tragic death of M. Nakashidze in 1906. So at the beginning of WWI Russians had only one combat unit of armored vehicles - first car-machine-gun company, which mainly used armored vehicles "Russo-Balt Type C".
Nevertheless, when they had to modernize the army hastily, the Russian army received several types of armoured vehicles rather soon.
