World War II

On 15 September 1942 the 184th Artillery Regiment "Nembo" was formed in Pisa. The regiment consisted of a command, a command unit, and two groups with 47/32 anti-tank guns. The regiment was assigned to the 184th Infantry Division "Nembo", which also included the 183rd Infantry Regiment "Nembo", 184th Infantry Regiment "Nembo", 185th Infantry Regiment "Nembo", and CLXXXIV Paratroopers Sappers Battalion. As the Nembo division was the Royal Italian Army's second paratroopers division, the personnel of the 184th Artillery Regiment "Nembo" had been trained at the Italian Royal Air Force's Paratroopers School in Tarquinia. On 1 February 1943 the 183rd Infantry Regiment "Nembo" joined the division and consequently the artillery regiment added a third group.^[1][2]

On 30 May 1943 regiment of the division received their flags in a ceremony in Florence.^[3] In early June 1943 the division was transferred to Sardinia, while the 185th Infantry Regiment "Nembo" and the III Paratroopers Artillery Group were detached. In Sardinia the division was assigned to XIII Army Corps, which was responsible for the defense of the southern half of the island. The division was intended to act as rapid reinforcement for the coastal units garrisoning the beaches, where allied forces were expected to land.^[4]

The announcement of the Armistice of Cassibile on 8 September 1943 saw the division, with the exception of one battalion, which sided with the German, remain inactive. In January 1944 the 184th Artillery Regiment "Nembo" returned to Italy, where its two groups were equipped with more powerful 75/27 field guns, respectively 100/22 mod. 14/19 howitzers. One month later the regiment also added an anti-aircraft battery with 20/65 mod. 35 anti-aircraft guns.^[1][2]

In May the rest of the division was transferred to mainland Italy and joined the Italian Co-belligerent Army's Italian Liberation Corps and entered combat.^[5][6]

In July 1944 the Nembo fought in the Battle of Ancona and distinguished itself in the liberation of Filottrano. In August 1944 the regiment received a third group equipped with British QF 6-pounder anti-tank guns. On 24 September 1944 the Nembo division was disbanded and its personnel used to form the Paratroopers Regiment "Nembo" and various support units for the Combat Group "Folgore". The 184th Artillery Regiment "Nembo" was assigned to the Combat Group "Folgore", renamed Artillery Regiment "Folgore", and re-equipped with British guns. The regiment now consisted of the following units:^[1][2]

On 19 April 1945 the II Battalion of the Paratroopers Regiment "Nembo" fought a heavy battle against the Fallschirmjäger of the German 1. Fallschirmjäger-Division at Case Grizzano, which opened the way for the allied armies to liberate Bologna.^[1][2]

For its conduct at during the Italian campaign the regiment was awarded a Silver Medal of Military Valor, which was affixed to the regiment's flag and is depicted on the regiment's coat of arms.^[1]

Cold War

After the war the regiment was based in Montecatini Terme. On 15 October 1945 the Combat Group "Folgore" was reorganized as Infantry Division "Folgore". In 1946 the regiment moved from Montecatini to Lucca. On 15 January 1947 the regiment was renamed 184th Artillery Regiment "Folgore" and on 1 February of the same year it ceded two of its groups equipped with QF 25-pounder field guns, as well as its VI Group to help reform the 33rd Field Artillery Regiment. In April of the same year the regiment ceded its V Group to help form the 41st Anti-tank Field Artillery Regiment.^[1][2][7]

At the beginning of 1948 the regiment was renamed 184th Field Artillery Regiment and moved from Lucca to Pordenone. The regiment consisted now of a command, a command unit, the I, II, and III groups with QF 25-pounder field guns, and the Mountain Artillery Group "Belluno", which had been formed on 22 August 1947. On 1 March 1948 the Mountain Artillery Group "Belluno" was transferred to the Artillery Command of the V Territorial Military Command. In 1949 the regiment moved from Pordenone to Treviso.^[1][7]

On 1 January 1951 the Infantry Division "Folgore" included the following artillery regiments:^[1][7]

On 1 February 1951 the regiment received an anti-aircraft group with 40/56 autocannons from the 5th Light Anti-aircraft Artillery Regiment. On 30 June 1951 the Italian Army's artillery was reorganized and the next day the regiment consisted of the following units:^[1][7]

In 1952 the two anti-tank groups were equipped with M18 Hellcat tank destroyers. On 1 July 1953 the 184th Field Artillery Regiment was disbanded and its personnel and equipment used to reform the 5th Mountain Artillery Regiment of the Alpine Brigade "Orobica", while the IV Group and V Group were transferred to the 33rd Field Artillery Regiment.^[1][2][7]

During the 1975 army reform the army disbanded the regimental level and newly independent battalions and groups were granted for the first time their own flags. On 31 December 1975 the 33rd Field Artillery Regiment of the Infantry Division "Folgore" was disbanded and the next day the regiment's IV Heavy Field Artillery Group in Treviso was reorganized and renamed 184th Heavy Self-propelled Field Artillery Group "Filottrano". To avoid confusion with the 183rd Mechanized Infantry Battalion "Nembo", the group was named for Filottrano, where the 184th Artillery Regiment "Nembo" had distinguished itself in July 1944. The group was assigned to the Artillery Command of the Mechanized Division "Folgore" and consisted of a command, a command and services battery, and three batteries with towed M114 155mm howitzers.^[1][7]

On 1 April 1976 the group moved from Treviso to Padua. On 12 November 1976 the group was assigned the flag and traditions of the 184th Artillery Regiment "Nembo" by decree 846 of the President of the Italian Republic Giovanni Leone.^[1][7][8] Although the group was designated as a self-propelled unit, the planned transition from towed M114 155mm howitzers to M109G 155mm self-propelled howitzers did not occur. At the time the group with its towed howitzers fielded 433 men (31 officers, 53 non-commissioned officers, and 349 soldiers).^[9]

On 27 September 1980 the group was equipped with modern towed FH70 155mm howitzers. On 1 July 1986 the group was assigned to the Artillery Command of the 4th Alpine Army Corps and the next year the group moved from Padua to Trento, where it took over the base of the II Group of the disbanded 4th Heavy Field Artillery Regiment.^[1][7]

Recent times

On 2 April 1991 the batteries of the Mountain Artillery Group "Vicenza" in Elvas were disbanded and the flag of the 2nd Mountain Artillery Regiment was transferred to Trento, where it supplanted the flag of the 184th Heavy Self-propelled Field Artillery Group "Filottrano", which one week later, on 9 April 1991, supplanted the flag of the 46th Self-propelled Field Artillery Group "Trento" in Gradisca d'Isonzo. Afterwards the flag of the 46th Artillery Regiment "Trento" was transferred to the Shrine of the Flags in the Vittoriano in Rome. The 184th Self-propelled Field Artillery Group "Filottrano" was assigned, together with the 183rd Mechanized Infantry Battalion "Nembo" in Gradisca d'Isonzo, to the Mechanized Brigade "Gorizia". Now finally the group was equipped with self-propelled howitzer, specifically M109L 155mm self-propelled howitzers.^[1][7]

On 25 August 1993 the 184th Self-propelled Field Artillery Group "Filottrano" lost its autonomy and the next day the group entered the 184th Self-propelled Field Artillery Regiment "Nembo". On 24 October 1996 the flag of the 184th Artillery Regiment "Nembo" was returned to the Shrine of the Flags in the Vittoriano in Rome and on 30 October the 184th Self-propelled Field Artillery Regiment "Nembo" and the Mechanized Brigade "Gorizia" were disbanded.^[1][7]
