Italy

The Fiat 15 was the stalwart of the first motorization of the Italian armed forces and the Royal Army acquired all versions of the truck in many configurations, including ambulance, garage, and fire engine. Alongside its use as a logistic means, Italy was the first country to use the motor vehicle directly in combat.^[6]

In fact, the Fiat 15 bis was used as the basis for the construction of the armored car Fiat Arsenale,^[7] used in the Italo-Turkish war together with the Bianchi. After the Great War, the Fiat-Terni Tripoli bus was produced on the chassis of the Fiat 15 ter by the steel mills of Terni. During this campaign, the squadrons were also motorized with numerous Fiat 15 ter trucks (defined at the time as "tanks"), protected with armored metal plates and armed with three Schwarzlose machine guns with 15,000 rounds, conducted by a crew of four men.^[8]

In 1918, the Italian army counted 8,206 Fiat 15 trucks in its ranks, including 710 in sanitary version.^{[citation needed]}

France

In 1907, the French Ministry of War had decided to reserve its orders to national manufacturers only. But in October 1914, it was realized that national production could not satisfy the needs of the French Army; 2,585 vehicles were delivered by the French national manufacturers in 1914. As such, foreign designs were pursued by the French government to fulfill its remaining vehicle deficit, and the Fiat 15 and 18 trucks were supplied by Fiat to serve in the French Army throughout the First World War.^{[citation needed]}

A first order for 500 units of the Fiat 15 came through in December 1914, followed by a second order for 600 vehicles in January 1915. On 30 June 1915, there were 635 Fiat 15 trucks in service with the French Army. On 31 May 1918, 839 trucks were assigned to aviation squadrons.^{[citation needed]}

Other countries

The Fiat 15 Ter was used by several other armies during the First World War. The United Kingdom obtained 386 trucks, while the United States received only 200, despite an order for 4,000 units.^{[citation needed]}

Many copies were also delivered to Russia; 1,319 trucks were assembled at the AMO factory in Moscow between 1917 and 1919 with parts supplied by Fiat. The Fiat 15 Ter was then manufactured under license by AMO under the name of AMO F-15, with 6,285 trucks built between 1924 and 1931.^[2][3]
