The regiment belongs to the Italian Army's Alpini infantry speciality and was last assigned to the Alpine Brigade "Tridentina".

[1][2] On 22 December 1935, the Royal Italian Army formed the command of the 11th Alpini Regiment in the city of Bruneck.

On 6 January 1936 the "Pusteria" division, which had been formed for the Second Italo-Ethiopian War, embarked in Livorno and Naples for the transfer to Massawa in Eritrea.

The same month the 6th Alpini Regiment formed the command and the 643rd Company of the XI Replacements Battalion.

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

After the end of the war the "Pusteria" remained in Ethiopia and was tasked with subjugating the restive population.

In March 1937, the "Pusteria" division returned to Italy, where its last units disembarked in Naples on 12 April 1937.

The regiment was also awarded a Bronze Medal of Military Valor for its service and conduct in the war, while the Alpini Battalion "Trento" was awarded a separate Bronze Medal of Military Valor for its service and conduct in the war.

[1][2] On 10 June 1940, the day Italy entered World War II, the regiment fielded 160 officers and 5,046 other ranks for a total strength of 5,206 men.

[1][2] In November 1940, the 5th Alpine Division "Pusteria" was transferred to Albania to shore up the crumbling Italian front during the Greco-Italian War.

By late November 1940, the 11th Alpini Regiment entered the front in the Berat sector.

The regiment retreated into Albania, where it continued to fight until the German invasion of Greece in April 1941.

[1][2][3][5] For their conduct and service on the Greek front between November 1940 and April 1941 the Alpini battalions "Trento" and "Bolzano" were both awarded a Silver Medal of Military Valor, which were both affixed to the 11th Alpini Regiment's flag and added to the regiment's coat of arms.

[1][2] After the conclusion of the Greco-Italian War and the Invasion of Yugoslavia in April 1941 the "Pusteria" division was sent in July 1941 as occupation force to Pljevlja in Montenegro.

Soon the division was embroiled in heavy fighting against Yugoslavian Partisans, which culminated in the Battle of Pljevlja in December 1941.

[1][2] In August 1942, the division was repatriated, and - after two months of rest - participated in the Axis occupation of Vichy France.

[1][2] 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.
