The 17th Anti-aircraft Artillery Regiment "Sforzesca" (Italian: 17° Reggimento Artiglieria Controaerei "Sforzesca") is an anti-aircraft artillery regiment of the Italian Army. Originally an artillery regiment of the Royal Italian Army, the regiment fought on the Italian front in World War I, and was assigned in World War II to the 2nd Infantry Division "Sforzesca", with which the regiment was deployed to the Eastern Front, where division and regiment were destroyed during Operation Little Saturn. Reformed in 1947 the regiment transferred from the field artillery to the anti-aircraft specialty on 1 July 1953. Today the regiment is based in Sabaudia in Lazio and assigned to the Anti-aircraft Artillery Command.^[3][4] The regimental anniversary falls, as for all Italian Army artillery regiments, on June 15, the beginning of the Second Battle of the Piave River in 1918.^[4]

On 1 November 1888 the 17th Field Artillery Regiment was formed in Novara. The new regiment consisted of eight batteries and one train company ceded by the 5th Field Artillery Regiment. The ceded batteries had participated in the First, Second, and Third Italian War of Independence, as well as the Piedmontese invasion of Central and Southern Italy in 1860–61.^[4][1][5]

In 1895-96 the regiment formed for the First Italo-Ethiopian War the 1st Mountain Artillery battery, which fought in the Battle of Adwa. The regiment also provided 139 troops for units deployed to Eritrea for the war. In 1911-12 the regiment provided for the Italo-Turkish War one group command and two batteries, as well as 235 troops for other units.^[4]

On 29 February 1912 the regiment ceded its III Group to help form the 25th Field Artillery Regiment, and in April of the same year the regiment provided personnel to help form the 1st Heavy Field Artillery Regiment.^[4]

At the outbreak of World War I the regiment was assigned, together with the Brigade "Como" and Brigade "Umbria", to the 2nd Division. At the time the regiment consisted of a command, three groups, and a depot. During the war the regiment's depot formed the command of the 4th Heavy Field Artillery Grouping, and the X, XIII, XVII, XXXVIII, and CII heavy field howitzer groups. The regiment's depot also formed 17 heavy field howitzer batteries and two siege batteries. During the war the regiment fought on the Sass de Stria, Col di Lana, and Monte Piana in 1915, on the Forcella Travenanzes in 1916, and on Monte Santo and on Škabrijel during the Eleventh Battle of the Isonzo in 1917. During the retreat to the Piave river after the Battle of Caporetto the regiment defended the bridge over the Piave at Vidor. In 1918 the regiment fought at Monastier and Fossalta during the Second Battle of the Piave River, and again at Monastier during the Battle of Vittorio Veneto.^[4]

After the war the regiment moved in 1920 from Novara to the newly annexed Monfalcone, where it remained only for one year before returning in 1921 to Novara. In 1926 the regiment was assigned to the 2nd Territorial Division of Novara and consisted of a command, one group with 100/17 mod. 14 howitzers, two groups with 75/27 mod. 11 field guns, one group with mule-carried 75/13 mod. 15 mountain guns, and a depot.

On 1 September 1939 the regiment's depot in Novara reformed the 59th Artillery Regiment "Cagliari" for the 59th Infantry Division "Cagliari". Two days later, on 3 September, the regiment ceded one of its 75/27 mod. 11 groups to help reform the 36th Artillery Regiment "Forlì" for the 36th Infantry Division "Forlì".^[4][1]

As replacement the Sforzesca received two groups with 75/18 mod. 35 howitzers, one of which arrived from the 108th Artillery Regiment "Cosseria", and one group with 105/28 cannons, which was transferred from the 1st Army Corps Artillery Regiment.
