These two regiments were the " His Royal Highness Fusilier Regiment " ( " Reggimento Fucilieri di Sua Altezza Reale " ) founded on 20 February 1690 and a newly raised Infantry Regiment . From 1 November 1815 to 25 October 1831 the " HRH Fusilier Regiment " was known as " Brigade of Aosta " ( " Brigata di Aosta " ) , however in size and function this brigade was an infantry regiment with just two battalions . Between 1774 and 1799 the " HRH Fusilier Regiment " was known as the " Regiment of Aosta " ( " Reggimento di Aosta " ) . Initially each regiment consisted of three battalions : the 1st and 2nd battalions fielded each three companies of fusilier s and one company of grenadier s , while the third battalions consisted of four companies of skirmisher s . A fourth battalion was added to each regiment and the companies personnel strength was increased . By 1839 each regiment fielded four battalions , which in turn fielded 4 companies of 250 men each . In 1839 the regiments of the " Aosta " were numbered and renamed as 5th Infantry Regiment " Aosta " Brigade and 6th Infantry Regiment " Aosta " Brigade . The brigade participated in the First Italian War of Independence fighting in the battles of Santa Lucia , Goito , Pastrengo and Novara , where the 5th Regiment was awarded a Silver Medal of Military Valor .

In the Third Italian War of Independence the brigade fought in the Battle of Custoza . Single battalions of the brigade were employed in the First Italo - Ethiopian War and the Italo - Turkish War . World War I . At the outbreak of World War I the brigade was based in the city of Gemona with its two regiments fielding three battalions each and each of the battalions consisting of four companies and a machine gun section . The 6th Regiment was the first to see action on the Italian front when it tried to conquer the Plöcken Pass on 3 July 1916 . Afterwards the brigade reinforced by two battalions of Alpini was given the task to conquer Monte Rombon . In 1916 the brigade was engaged in combat in the region of Kras . 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 managed to end the Austrian advance after the Battle of Caporetto .

For this last engagement of the World War I the " Aosta " brigade was awarded its second Gold Medal of Military Valor . World War II . After the end of World War I the brigade moved to Sicily and was garrisoned in the city of Palermo . In 1926 the brigade gained the 85th Infantry Regiment " Verona " and changed its name to XXVIII Infantry Brigade . Along with the 22nd Artillery Regiment the brigade formed the 28th Division . In 1939 the brigade lost the 85th Infantry regiment and was renamed 28th Infantry Division " Aosta " . This binary division consisted of only two infantry regiments ( 5th and 6th ) and the 22nd Field Artillery Regiment . The division remained based in Sicily and was tasked to defend the island against landings by Allied forces . 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 . The remnants of the division were evacuated to mainland Italy between 9 to 12 August 1943 . After the Armistice between Italy and Allied armed forces of 8 September 1943 the division was disbanded by German Forces . On 20 September 1944 the " Aosta " was raised again on Sicily as part of the Italian Co - Belligerent Army . The new unit was named " Aosta " Internal Security Division and consisted of the III and IV Internal Security Brigades . Cold War . On 15 August 1946 the " Aosta " Internal Security Division renamed and reformed as " Aosta " Infantry Brigade on Sicily . On 1 September 1946 the regiments of the division returned to their old names 5th respectively 6th Infantry Regiment " Aosta " and were based in Messina and Palermo . With the expansion of the Italian Army after World War II the brigade was expanded to a full division on 1 February 1948 and the two " Aosta " infantry regiments were joined by the 46th Infantry Regiment " Reggio " and the 22nd and 24th Field Artillery Regiment . However already on 15 June 1955 the division began to shrink with the disbandment of the 6th Infantry Regiment . The III Battalion of the 5th Infantry Regiment received the colors and traditions of the disbanded regiment . The Division was under the command of the XI Military Territorial Command / Sicily Military Region in Palermo , which had administrative command of all units based in Sicily and was tasked with the defense of the islands of Sicily , Pantelleria and Pelagie . On 21 February 1961 the division was reduced once more to infantry brigade and consisted now of the 5th Infantry Regiment " Aosta " ( with three infantry battalions ) , the LXII Armored Battalion and the Field Artillery Group " Aosta " . Minor units of the brigade were a Signals and an Engineer company . During the next years the " Aosta " Logistic Battalion was raised in Messina . The 46th Infantry Regiment " Reggio " turned into a training unit under direct command of the XI Military Territorial Command . On 1 October 1975 the Italian Army abolished the regimental level and battalions came under direct command of the brigades . Therefore the 5th Regiment was disbanded and its three battalions came forthwith under direct command of the " Aosta " Motorized Infantry Brigade . The new organization of the brigade was therefore : The brigade was continued to be under command of the XI Military Territorial Command / Sicily Military Region in Palermo . As the command was tasked with defending the outlying islands of Pantelleria and Pelagie a battalion staff was activated on Pantelleria and Aosta units rotated to the island on garrison duties . Besides the " Aosta " the following units were part of the XI Military Territorial Command : Today . When in 1991 the Italian Army disbanded a large number of its mechanized brigades in Northern Italy after the end of the Cold War , the " Aostas " infantry battalions received VCC - 2 armored personnel carriers , while the 24th " Peloritani " was equipped with M109 self - propelled howitzers . Accordingly the brigade changed its name on 18 August 1992 to " Aosta " Mechanized Brigade . In the same year the brigade began its six - year involvement in the Operation " Sicilian Vespers " a security and policing operation in Sicily undertaken by the Italian armed forces between 25 January 1992 and 8 July 1998 . 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 . During the late 1990s the " Lancieri di Aosta " regiment exchanged its Leopard 1A2 main battle tank s for Centauro wheeled tank destroyer s , while the rest of the brigade received new vehicles after 2010 . In 2013 the brigade gained the " Aosta " Logistic Regiment in Messina . Today the brigade is composed of the following units : All regiment s are battalion sized . Equipment .
