The regiment belongs to the Italian Army's Alpini infantry speciality and is assigned to the Alpine Training Center in Aosta.

[3][4][5] During World War I the regiment expanded to ten battalions, which fought separately in the alpine areas of the Italian front.

[2][3][4][5] On 10 April 1946, the 6th Alpini Regiment was reformed and in 1951 assigned to the Alpine Brigade "Tridentina".

[3][4][5] On 15 October 1872, the Royal Italian Army formed 15 locally recruited Alpini companies in the alpine regions of Northern Italy.

Upon entering the regiments, the battalions, which until then had been designated by a Roman numeral, were named for their recruiting zone, while the Alpini companies were renumbered sequentially from 1st to 72nd.

On 1 November 1886, the battalions changed their names from their recruiting zones to the cities and towns, where their base was located.

In 1895-96 the regiment provided 19 officers and 523 troops to help form the I and V provisional Alpini battalions, which were deployed to Eritrea for the First Italo-Ethiopian War.

On 18-19 June 1913, the battalion distinguished itself in the Battle of Ettangi against local rebel forces and was awarded a Silver Medal of Military Valor, which was affixed to the flag of the 6th Alpini Regiment and added to the regiment's coat of arms.

[2][4][5] At the outbreak of World War I the Alpini speciality consisted of eight regiments, which fielded 26 battalions with 79 companies.

After Italy's initial declaration of neutrality 38 additional Alpini companies were formed during the autumn of 1914 with men, who had completed their military service in the preceding four years.

Around the same time the Alpini Battalion "Monte Baldo" was disbanded after its return from Upper Silesia.

On 6 January 1936, the "Pusteria" division's units embarked in Livorno and Naples for the transfer to Massawa in Eritrea.

The XI Replacements Battalion was attached to 11th Alpini Regiment and shipped to East Africa, where in the meantime the "Pusteria" was engaged in combat against Ethiopian troops.

[5][7] In November 1940, the 2nd Alpine Division "Tridentina" was transferred to Albania to shore up the crumbling Italian front during the Greco-Italian War.

By now the "Tridentina" division had retreated into Albania, where it continued to fight until the German invasion of Greece in April 1941.

[2][5][7] In December 1941, the regiment formed the XVIII Replacements Battalion, which was assigned to the 7th Alpini Valley Group, which fought Yugoslav partisans in Croatia.

The corps was assigned to the Italian 8th Army, which was readied to be deployed in summer 1942 to the Eastern Front.

In preparation for the deployment to the Soviet Union the 6th Alpini Regiment's depot formed on 1 April 1942 the 216th Cannons Company, which was equipped with 47/32 mod.

The division provided replacement troops for the 8th Army's regiments fighting on the Eastern Front.

[5][7][22][20] In July 1942 the three alpine division arrived in Eastern Ukraine, from where they marched eastwards towards the Don river.

On 1 September 1942, the Alpini Battalion "Vestone" assaulted three Soviet-held heights near the Don river, which were taken after a day of bloody fighting.

[5][7][21][22][23] On the evening of 17 January 1943, the Alpine Army Corps commander, General Gabriele Nasci, ordered a full retreat.

The 40,000-strong mass of stragglers — Alpini and Italians from other commands, plus German and Hungarians — followed the "Tridentina", which led the way westwards to the new Axis lines.

On the morning of 26 January 1943, the spearheads of the "Tridentina' reached the hamlet of Nikolayevka, occupied by the Soviet 48th Guards Rifle Division.

General Nasci ordered a frontal assault and at 9:30 am the Battle of Nikolayevka began with the 6th Alpini Regiment leading the first attack.

By noon the Italian forces had reached the outskirts of the village and the Alpine Army Corps' Chief of Staff General Giulio Martinat led the 5th Alpini Regiment forward for another assault, durich which General Martinat fell.

[23] By sunset the Alpini battalions were still struggling to break the Soviet lines and in a last effort to decide the battle before nightfall General Luigi Reverberi, the commanding General of the "Tridentina" division, ordered a human wave attack on the Soviet lines.

After the announcement of the armistice the Alpini Battalion "Monte Baldo" fought against German forces retreating through Corsica.

[5][7] On 20 November 1945, the IV Brigade of the 210th Auxiliary Division, which had served with the American Fifth Army during the Italian campaign of World War II, was reorganized in the city of Meran as an Alpini regiment.

On the same day the 5th Alpini Regiment joined the newly formed Alpine Brigade "Orobica".
