# 4th Anti-Aircraft Artillery Regiment "Peschiera"

The 4th Anti-aircraft Artillery Regiment "Peschiera" (Italian: 4° Reggimento Artiglieria Controaerei "Peschiera") is an air defence regiment of the Italian Army. Originally an air defence regiment of the Royal Italian Army, the regiment is now based in Mantua in Lombardy and assigned to the Anti-aircraft Artillery Command. During the Cold War, the regiment was equipped with MIM-23 Hawk air defence missile systems and formed, together with the 5th Anti-aircraft Missiles Artillery Regiment, the air defence belt of the Italian Army in the country's Northeast. 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.

## History

On 1 November 1926, the 4th Anti-aircraft Artillery Center was formed in Peschiera, with the existing 3rd Anti-aircraft Group and one group from the disbanded 14th Heavy Artillery Regiment. After being formed, the center moved from Peschiera to Mantua. On 1 January 1927, the center consisted of a command, a trucked group with 75/27 C.K. anti-aircraft guns, a positional group with 76/45 anti-aircraft guns, a photo-electricians unit, and a depot. The center's photo-electricians operated searchlights.
On 1 April 1930, the positional group was transferred to the 7th Heavy Artillery Regiment, while the 3rd Anti-aircraft Artillery Center ceded its trucked group with 75/27 C.K. anti-aircraft guns and its photo-electricians unit to the 4th Anti-aircraft Artillery Center. On 1 June of the same year, the center changed its name to 4th Trucked Anti-aircraft Artillery Regiment. In April 1931, the two photo-electricians units were disbanded and in each of the two trucked groups a photo-electricians section and an acoustic locator squad.
On 1 January 1934, the regiment changed its name to 4th Anti-aircraft Artillery Regiment. In September 1935, the regiment was mobilized for the Second Italo-Ethiopian War deployed to the city of Marsala in Sicily. The regiment's depot in Mantua formed the XI Group, which was deployed to Rome for the defence of the capital. On 10 March 1936, the regiment's depot formed the 256th and 257th positional batteries, which were transferred to Italian Libya, where they joined the 2nd Colonial Artillery Regiment. The regiment was demobilized in July 1936 and consisted of a command, a command battery, two groups of three batteries each, and a training battery.
On 10 January 1938, the regiment formed the 7th Trucked Battery with 75/46 mod. 34 anti-aircraft guns, which in June of the same year, was sent to Spain as part of the Corpo Truppe Volontarie, which supported the Nationalist forces under General Francisco Franco against the Spanish Republic during the Spanish Civil War.

### World War II

At the outbreak of World War II, the regiment consisted of a command, a command unit, the II, IX, and XI groups with 75/27 C.K. anti-aircraft guns, XVII and XXII groups with 75/46 mod. 34 anti-aircraft guns, and one group with 20/65 mod. 35 autocannons. On 10 June 1940, the day Italy entered the war, the regiment was assigned to the Artillery Command of the 1st Army. On 28 June, the XVII and XXII groups were sent to Italian Libya for the Western Desert campaign. In early 1941, the XI Group was sent to occupied Albania, where it participated in the Greco-Italian War.
During the war, the regiment's depot in Mantua mobilized the following units:

The grouping was assigned to the 8th Army, which was sent to the Eastern Front. The grouping departed from Mantua on 13 June 1942. Upon arrival in Russia, the IV and XIX trucked groups with 75/46 mod. 34 anti-aircraft guns of the 5th Anti-aircraft Artillery Regiment were assigned to the grouping. The two groups had been deployed with the Italian Expeditionary Corps in Russia to the Soviet Union in July 1941. On 16 December 1942, the Red Army commenced Operation Little Saturn and the anti-aircraft troops were forced to use their anti-aircraft guns in the anti-tank role. Even though the Italian divisions resisted for two weeks the Soviet offensive destroyed most of the Italian 8th Army, and with it most of the 4th Anti-aircraft Artillery Regiment. The remnants of the grouping were repatriated in March 1943. For its conduct in the Soviet Union, the grouping was awarded a Bronze Medal of Military Valor, which today is affixed to the flag of the 4th Anti-aircraft Artillery Regiment "Peschiera" and depicted on its coat of arms.
The regiment and its depot were disbanded by invading German forces after the announcement of the Armistice of Cassibile on 8 September 1943.
