It was the only serially produced armoured car built by the White Army, and were used exclusively by the Siberian Army on the Eastern Front in the Siberia and Russian Far East regions.

The Fiat-Omsky vehicles were commissioned by Admiral Alexander Kolchak, the leading White commander on the Eastern Front, following his return from the United States.

The Fiat-Omsky was constructed using Fiat Tipo 5 chassis supplied from the United States, with different variations equipped with light armour plating and one or two PM M1910 machine guns attached to wheelhouses on sponsons.

There are discrepancies in the construction of the Fiat-Omsky, as there are no known records of the designers, as well as the time and location of their manufacture.

Two of the cars entered active service in the People's Revolutionary Army of the Far Eastern Republic until 1921, when they were decommissioned.
