Furthermore, the IV Battalion of the 5th Regiment was awarded a Bronze Medal of Military Valor for its conduct during the Battle of Aspromonte.

From 22 to 26 November 1917 the brigade defended the summit of Col della Berretta on the Monte Grappa massif during the Battle of Monte Grappa, which put an end the Austrian offensive after the Battle of Caporetto.

In October 1918 the brigade conquered the summit of Monte Valderoa and held it against repeated Austrian counterattacks.

For this last engagement of the war the "Aosta" Brigade's two regiments were awarded their second Gold Medal of Military Valor.

After the end of World War I the brigade moved to Sicily and was garrisoned in the city of Palermo.

The brigade was the infantry component of the 28th Territorial Division of Palermo, which also included the 22nd Artillery Regiment.

[1] On 9 July 1943 the Allied invasion of Sicily began and the division was badly mauled by US Army troops during the Battle of Troina in the North of the island.

[1] On 20 September 1944 the Italian Co-Belligerent Army formed in Sicily the III and IV internal security brigades with the regiments of the disbanded 47th Infantry Division "Bari".

Therefore, on 1 October 1975 the 5th Regiment was disbanded and its three battalions came forthwith under direct command of the Motorized Brigade "Aosta".

Besides the Aosta the following units were part of the XI Military Territorial Command after the reform:[16] With the end of the Cold War the Italian Army began to disbanded a large number of its mechanized brigades in Northern Italy and redistributed their materiel: the Aosta received VCC-2 armored personnel carriers for its infantry battalions and M109 self-propelled howitzers for the 24th "Peloritani".

[1] After the end of the Cold War the brigade continuously changed composition as the Italian Army was drawing down its forces and moving a large number of units from the North to the South of the country, as most volunteers came from the economically less developed Southern regions.

The "Lancieri di Aosta" regiment is equipped with Centauro wheeled tank destroyers and VTLM Lince vehicles.
