# 3rd Armored Infantry Regiment (Italy)

The 3rd Armored Infantry Regiment (Italian: 3° Reggimento Fanteria Corazzato) is an inactive armored warfare regiment of the Italian Army, which was based in Persano in Campania and last operationally assigned to the Infantry Division "Granatieri di Sardegna". The regiment was formed in 1927 as Armed Tanks Regiment. In 1936 the regiment was split into four tank infantry regiments and the 3rd Tank Infantry Regiment was assigned the flag and traditions of the Armed Tanks Regiment. During World War II the battalion served as central training command for all Italian tank units. The regiment was disbanded by German forces after the Armistice of Cassibile was announced on 8 September 1943.
In 1964 the regiment was reformed as 3rd Armored Infantry Regiment and assigned to the Infantry Division "Granatieri di Sardegna". In 1975 the regiment was disbanded and its flag and traditions transferred to the 9th Armored Battalion "M.O. Butera", which was assigned to the Motorized Brigade "Acqui". In 1991 the battalion was disbanded and the flag of the 3rd Armored Infantry Regiment transferred to the Shrine of the Flags in the Vittoriano in Rome. From 1992 to 1995 the 9th Armored Battalion "M.O. Butera" was again active as a training support unit at the Monte Romano training range. Originally the unit, like all Italian tank units, was part of the army's infantry arm, but on 1 June 1999 the tankers specialty was transferred from the infantry arm to the cavalry arm. The regiment's anniversary falls on 5 January, the last day of the Battle of Bardia, which concluded the operational cycle 1940-41 of the Western Desert campaign.

## History
### Interwar years

On 1 October 1927, the Royal Italian Army reorganized its Armed Tanks Formation Center in Rome and formed the Armed Tanks Regiment (Italian: Reggimento carri armati) as central training unit for the army's tank battalions. Initially the regiment, which had raining and administrative functions only, consisted of five tank battalions and one armored cars machine gun battalion, which was not yet formed. The tank battalions were equipped with Fiat 3000 Mod. 21 light tanks, while the armored cars machine gun battalion was to receive Lancia 1ZM armored cars. On 28 August 1928, the regiment's IV Battalion moved from Rome to Udine, and on 1 September of the same year the V Battalion moved from Rome to Codroipo. On 5 January 1931, the V Battalion moved from Codroipo to Bologna, as on 15 January the armored cars machine gun battalion was finally formed in Rome and then transferred to Codroipo. On 1 October of the same year, the regimental command and depot, which included training and maintenance units, moved from Rome to Bologna.
On 20 May 1932, the III Battalion moved from Rome to Bassano del Grappa, which left only the I and II battalions in Rome. On 28 June 1934, the regiment formed with parts ceded by its tank battalions, the Fast Tanks Squadron, which on 1 September of the same year was transferred to Italian Eritrea. On 22 August 1934, the III Battalion left Bassano del Grappa and moved to Mantua and one year later to Brescia. In 1933 the production of the CV33 tankette (with CV standing for Italian: "Carro Veloce" or Fast Tank) commenced and by 1934 full rate production was underway. Consequently the regimental depot in Bologna began to form assault tank battalions, which were intended as support units for the army's corps formations. At the time all tank battalions were named for infantry officers, who had served in World War I and been awarded posthumously Italy's highest military honor the Gold Medal of Military Valor. To distinguish the battalions equipped with CV33 tankettes from the battalions equipped with Fiat 3000 light tanks the latter were redesignated as breach tanks battalions.
In early 1935 the depot formed the IV Assault Tanks Battalion "Monti", which moved to Bolzano and supported the IV Army Corps, the V Assault Tanks Battalion "Suarez" (later renamed "Venezian"), which moved to Trieste and supported the V Army Corps, the VI Assault Tanks Battalion "Lollini", which moved to Treviso and supported the VI Army Corps, and XI Assault Tanks Battalion "Gregorutti", which moved to Udine and supported the XI Army Corps. In June 1935, the depot formed the XXI Assault Tanks Battalion "Trombi", XXII Assault Tanks Battalion "Coralli", and XXXII Assault Tanks Battalion "Battisti", which were transferred to Italian Libya on garrison duty for the duration of the Second Italo-Ethiopian War. In September of the same year, the depot formed the XX Assault Tanks Battalion "Randaccio", which was transferred to Italian Eritrea, where it fought the Second Italo-Ethiopian War.
In March 1936, the depot formed the XXIII Assault Tanks Battalion "Stennio" and the XXXI Assault Tanks Battalion "Cerboni" for service in Libya. On 10 May 1936, the depot formed the IX Assault Tanks Battalion "Guadagni", which moved to Bari and supported the IX Army Corps, and on 13 May the Assault Tanks Company Sardinia, which was then sent to the island of Sardinia. On 15 June 1936, the depot formed the VII Assault Tanks Battalion "Vezzani", which moved to Florence and supported the VII Army Corps, X Assault Tanks Battalion "Menzinger", which moved to Agnano and supported the X Army Corps and XII Assault Tanks Battalion "Cangialosi", which moved to Palermo and supported the XII Army Corps, and on 25 June the School Battalion, which assumed all training functions. At the beginning of September 1936, the XXIII Assault Tanks Battalion "Stennio" was assigned to the 8th Infantry Division "Po", which was being deployed to Libya for the duration of the Second Italo-Ethiopian War.
On 15 September 1936, the Armed Tanks Regiment was split into four tank infantry regiments, which had training and administrative functions only. The battalions of the Armed Tanks Regiment were divided among the new regiments as follows:

The 3rd Tank Infantry Regiment was assigned the flag and traditions of the Armed Tanks Regiment and remained the central training center for all officers and ranks destined for tank units. Additionally the regiment was administratively and logistically responsible for all tank units deployed in the Italian colonies of Libya, Eritrea, and Somaliland.
In fall 1936 the regiment added the XXI Assault Tanks Battalion "Stennio", and XXXII Assault Tanks Battalion "Battisti" after the two battalions returned from Libya. The same year assault tank battalions began to receive the improved L3/35 tankette and the 3rd Tank Infantry Regiment sent the first Italian tanks and troops to Spain, where they fought on the Nationalist side in the Spanish Civil War. On 25 April 1937, the Colonel Valentino Babini, who had been the commander of the 3rd Tank Infantry Regiment, arrived in Spain and took charge of the Specialized Units Grouping of the Italian Corpo Truppe Volontarie. In total Italy sent 149 L3/35 tankettes and eight Lancia 1ZM armored cars to Spain. On 15 July 1937, the regiment transferred the I Breach Tanks Battalion "Raggi" to the newly formed 31st Tank Infantry Regiment. In 1938, all Assault Tank Battalions were renamed Tank Battalion L (with L standing for Italian: "Leggero" or Light), while Breach Tanks Battalions were renamed Tank Battalion M (with M standing for Italian: "Medio" or Medium). On 1 October 1938, the Mechanized Company in Zadar was transferred to the Zara Troops Command. On 30 November 1938, the regiment transferred the VII Tank Battalion L to the 31st Tank Infantry Regiment, and the XXI Tank Battalion L to the 2nd Tank Infantry Regiment, while the Tank Company L Sardinia was transferred to the 4th Tank Infantry Regiment. In turn the 2nd Tank Infantry Regiment transferred the V Tank Battalion L and XI Tank Battalion L to the 3rd Tank Infantry Regiment. On 6 November 1939, the regiment transferred the VI Tank Battalion L and XXXII Tank Battalion L to the newly formed 33rd Tank Infantry Regiment.

### World War II

On 10 June 1940, the day Italy entered World War II the regiment was assigned to the reserve of the Italian 1st Army, which participated in the Italian invasion of France. At the time the 3rd Tank Infantry Regiment consisted of the following units:
* 3rd Tank Infantry Regiment, in Bologna

** School Battalion, in Bologna
** 3rd Maintenance Workshop, in Bologna
On 1 October 1940, the V Tank Battalion L was sent to Libya to augment the XX Army Corps, which was part of the Italian forces that invaded Egypt in September. Afterwards the regiment called up reservists and formed a Complements Battalion, which on 23 February 1941 was sent to Albania to help bring units fighting in the Greco–Italian War back up to full strength. At the same time the School Battalion was split into the I Complement Officer Cadets and Specialists School Battalion and the II Specialistes Worker Cadets School Battalion. For the remainder of the war the regiment provided the training for all personnel destined for tank units and managed the training grounds at Bologna, Porretta, Riolo, Vergato, Asiago, and Futa. The regiment was acted as the central research and test center for the army's armored vehicles.
In North Africa the V Tank Battalion L was assigned to the 17th Infantry Division "Pavia", with which it fought in the Western Desert campaign. In 1941 the Pavia division was part of the Axis force besieging Tobruk, which was held by the British 70th Infantry Division. On 18 November 1941, the British Eighth Army commenced Operation Crusader, which aimed to break the Siege of Tobruk. On 23 November 1941, the 70th Infantry Division attacked the Axis siege ring the Pavia was sent to stem the British breakthrough. On 6 December General Erwin Rommel ordered a retreat to the Gazala Line. For its conduct between 23 November and 5 December 1941 the V Tank Battalion L was awarded Bronze Medal of Military Valor, which was affixed to the flag of the 3rd Tank Infantry Regiment and added to the regiment's coat of arms.
On 21 March 1941, the 3rd Tank Infantry Regiment formed the IX Tank Battalion M13/40, which was equipped with M13/40 tanks and transferred on 21 July 1941 to Libya, where it joined the recently formed 132nd Tank Infantry Regiment. On 1 February 1942, the regiment disbanded the XI Tank Battalion L and its personnel was used to form the XVIII Tank Battalion M14/41, which was equipped with M14/41 tanks and was transferred on 1 July 1942 to the 33rd Tank Infantry Regiment.

During the Western Desert campaign the IX Tank Battalion L, which had been formed in 1936 and been assigned to the 4th Tank Infantry Regiment, when the Armed Tanks Regiment was split up, distinguished itself during the British Operation Compass. The battalion fought from the begin of the British offensive on 9 December 1940, until it was annihilated in the Battle of Bardia, with the battalion's survivors surrendering on 5 January 1941. For its conduct and sacrifice between 9 December 1940 and 5 January 1941 the IX Tank Battalion L was awarded Bronze Medal of Military Valor.

### Cold War

On 1 October 1964, the regiment was reformed as 3rd Armored Infantry Regiment in Persano. The regiment was operationally assigned to the Infantry Division "Granatieri di Sardegna", but also provided training support to the Mechanized and Armored Troops School in Caserta. On 25 March 1965, the regiment's IX Tank Battalion in Altamura was redesignated LX Armored Battalion and assigned to the Infantry Brigade "Avellino", while on the same date the LX Armored Battalion in Salerno was transferred from the Infantry Brigade "Avellino" to the 3rd Armored Infantry Regiment and redesignated IX Tank Battalion.

Tank and armored battalions created during the 1975 army reform were named for officers, soldiers and partisans of the tank speciality, who had served in World War II and been awarded Italy's highest military honor the Gold Medal of Military Valor. The 9th Armored Battalion was named for Gaetano Butera, a soldiers of the 4th Tank Infantry Regiment, who had joined the Italian resistance movement after the German occupation of Italy and was murdered by the SS on 24 March 1944 in the Ardeatine massacre.
