A corporal in the 2nd Field Artillery Regiment, Silvio Scaroni entered the Italian Air Service in March 1915. After training on Blériots and Caudrons, he joined the 4aSquadriglia as a reconnaissance pilot in September 1915. Promoted to First Lieutenant, he was reassigned to the 43aSquadriglia in January 1917. Later that year, he served briefly with the 86aSquadriglia before becoming a pursuit pilot with the 76aSquadriglia. Flying the Nieuport 17, Scaroni scored his first confirmed victory on 14 November 1917, shooting down an enemy two-seater near Colbertaldo. Re-equipped with the Hanriot HD.1, he scored three victories at the battle of Istrana on 26 December 1917 and soon became the highest scoring ace in his squadron. Wounded in action at Monte Tomatico, Scaroni scored his final victory on 12 July 1918, bringing down an Albatros D.III.
