It derives from the 2nd Armoured Brigade constituted on 15th July 1937 in Milan; its first unit was the 3rd Bersaglieri Regiment, followed by the 8th Bersaglieri Regiment and the 32nd Tank Infantry Regiment in November 1938.
On 1st February 1939 the Brigade was changed into 132nd "Ariete" Armoured Division, composed of the 8th Bersaglieri Regiment, the 32nd Tank Infantry and the 132nd Armoured Artillery.
Since 1st September 1941 the Division, deployed in Northern Africa, has also included the 132nd Tank Infantry Regiment that substituted the 32nd Regiment dissolved on 31st December 1941. On 8th December 1942 the Division disappeared during the battle of El Alamein.
In order to maintain a glorious tradition had in a short time, the "Ariete" was the most mentioned Army Unit by the war bulletins of the High Command during the Second World War. On 1st April 1943 in Italy the 135th "Ariete" Cavalry Armoured Division appeared, composed of the Cavalry Regiments of "Montebello", "Vittorio Emanuele II" and "Lucca", the 135th and 235th Artillery Regiments, the 134th self-propelled Antitank Battalion and the 134th Engineer Battalion. This big unit was dissolved on 12th September 1943 after the defence of Rome.
Since 23rd May 1948 the "Ariete" Armoured Group was instituted and on 1st June 1948 it formed the "Ariete" Armoured Brigade in Rome. The Brigade was composed of a Command, the 8th Bersaglieri Regiment, the 132nd Tank Regiment, the 132nd Artillery Regiment, and support units; since 1st October 1952 it became "Ariete" Armoured Division, including also the 19th "Guide" Explore Group, an Engineer Company and a Signals Company.
In 1963 the big unit assumed the standard OTAN staff and it was organized in 1st Mechanized Brigade (formed on 1st January in Pordenone with the 8th Bersaglieri Regiment, the 1st Group of the 132nd Armoured Artillery Regiment, the Services Battalion, the Engineer Company, the Signals Company); 2nd Armoured Brigade (formed on 1st October in Pordenone with the 32nd Tanks Regiment, the 2nd Group of the 132nd Armoured Artillery Regiment, the 2nd Services Battalion, an Engineer Company and a Signals Company); 3rd Armoured Brigade (formed on 1st January in Maniago with the 132nd Tanks Regiment, the 3rd Group of the 132nd Armoured Artillery Regiment, the 3rd Services Battalion, an Engineer Company, a Signals Company); Artillery Brigade (formed on 1st October in Casarsa with the 132nd Armoured Artillery Regiment Command, a Command Unit, Artillery Specialists Gun Battery, the 4th and 5th Group of the 132nd Armoured Artillery Regiment).
That organization was abandoned in October 1968 when the "Ariete" Brigade retook the previous organization.
With the reorganization of the Army, since 1st October 1975 it assumed at its dependencies the 32nd "Mameli" and the 132nd "Manin" Armoured Brigades, as well as the 8th "Garibaldi" Mechanized Brigade; there were also other support units.
On 1st October 1986 the Unit was dissolved and meanwhile the 132nd "Ariete" Armoured Brigade Command was instituted to change the Command of the suppressed "Manin" Brigade.
The new-formed unit included the 8th "M.O. Secchiaroli", the 10th "M.O. Bruno" and the 13th "M.O. Pascucci" Tanks Battalions, the 27th "Jamiano" Bersaglieri Battalion, the 20th Artillery Group for "Piave" self-propelled Campaign, the "Ariete" Logistics Battalion, an Antitank Company, an Engineer Company and a Command and Signals Unit.
The complements changed in 1989 (the 13th Tanks Battalion passed at the dependencies of the "Mantova" Mechanized Brigade), in 1991 (the 10th Tanks Battalion in January and the 20th Artillery Group for "Rialto" self-propelled Campaign in March, they are suppressed; they were assigned the 19th Artillery Group for "Rialto" self-propelled Campaign, the 3rd "M.O. Galas" Tanks Battalion, the 5th "M.O. Chiamenti" Tanks Battalion and the 23rd "Castel di Borgo" Bersaglieri Battalion) and in 1992 (the 2nd "Pordenone" Recruits Training Battalion was acquired while the 23rd Bersaglieri Battalion was moved to "Aosta" Mechanized Brigade).
With the new organization of the Armed Force that provided for the restoration of the regimental level, since 1992 the Brigade has had the following structure: Command, Command and Tactical Supports Unit, 32nd and 132nd Tanks Regiment, 11th Bersaglieri Regiment, 132nd Armoured Artillery Regiment, 26th "Castelfidardo" Battalion (that was already "Pordenone"), "Ariete" Logistics Battalion.
Since 1st December 2000 also the 10th Engineer Regiment was included and then, after the "Centauro" Mechanized Brigade was dissolved, the 3rd Bersaglieri Regiment and the 4th Tanks Regiment became part of the Brigade.
