In 1940 the division remained in Fenestrelle as a reserve force during the Italian invasion of southern France. After the Italian invasion of Greece in October 1940 bogged down under stiff Greek resistance the "Legnano" division was dispatched to Albania in January 1941 to augment the Italian forces under pressure by the Greek counteroffensive.
Already on 26 September 1943 parts of the division were used to form the I Motorized Grouping (Italian: 1° Raggruppamento Motorizzato), which was to aid in the allied war effort. The I Motorized Grouping consisted of the following units:
I Motorized Grouping (formed with officers and troops of the 58th Infantry Division "Legnano" Command Group)
363rd Anti-aircraft Battery with 20/65 mod. 35 anti-aircraft guns
Mixed Engineer Company
1st Telegraphers Engineer Platoon
1st Radiotelegraphers Engineer Platoon
1st Signal Engineer Platoon
Services (logistic, medical, transport, etc. units)
In the next months the division lost all its units, which were needed on the front lines. On 17 February 1944 the division was deactivated after its last units had joined other units.
Combat Group "Legnano
On 24 September 1944 the II Brigade of the Italian Liberation Corps ("Corpo Italiano di Liberazione", or CIL), was renamed as Combat Group "Legnano". The Combat Group consisted of the 68th Infantry Regiment "Palermo", the 11th Motorized Artillery Regiment, the elite IX Assault Unit and the Special Infantry Regiment "Legnano", which consisted of the remnants of the 3rd Alpini Regiment and 4th Bersaglieri Regiment. The Combat Group was equipped with British weapons and materiel. The combat group's structure when it entered the front was:
On 1 May 1958 the 4th Armored Infantry Regiment joined the division. The regiment consisted of the XX Tank Battalion with M47 Patton tanks and the II Bersaglieri Battalion. At the same time the 3rd Cavalry Regiment was reduced to Divisional Reconnaissance Group "Legnano". After the four artillery groups of the 11th Artillery Regiment had been re-equipped with M101 105 mm and M114 155 mm howitzers, the Horse Artillery Regiment was transferred to the III Army Corps.
The structure of the division before the 1975 reform was as follows:
Supply, Repairs, Recovery Unit "Legnano", in Orio al Serio
Transport Unit "Legnano", in Presezzo
Medical Battalion "Legnano" (Reserve), in Presezzo (includes the 5th Field Hospital)[8]
Provisions Supply Company "Legnano", in Presezzo
The Light Aviation Unit "Legnano", at Bergamo-Orio al Serio Air Base was disbanded on 16 July 1972.[9]
Mechanized Brigade "Legnano"
In 1975 the Italian Army undertook a major reorganization of it forces: the regimental level was abolished and battalions came under direct command of multi-arms brigades. Therefore, on 29 October 1975 the Infantry Division "Legnano" was split to form the Mechanized Brigade "Legnano" in Bergamo and the Mechanized Brigade "Brescia" in Brescia. The I and IV battalions of the 68th Infantry Regiment "Legnano" and the battalions of the 4th Armored Infantry Regiment were used to form the "Legnano" brigade. The I and III battalion of the 67th Infantry Regiment along with the III Battalion of the 68th Infantry Regiment were used to form the Mechanized Brigade "Brescia".
The 11th Field Artillery Regiment and its I and II groups were disbanded, while the III group was transferred to the 3rd Mechanized Brigade "Goito". The IV Heavy Field Artillery Group became the 11th Field Artillery Group "Monferrato" and remained with the "Legnano" brigade. The VII Reconnaissance Squadrons Group "Lancieri di Milano" was transferred to the Mechanized Division "Mantova", while the division's Signal Battalion, Engineer Battalion and Services Grouping were split among the two new brigades. After the reform the Legnano's authorized strength was 4,733 men (272 Officers, 637 non-commissioned officers and 3,824 soldiers) and it joined the Armored Division "Centauro". After the reform the brigade consisted of the following units:
In 1982 and 1983 the brigade provided personnel for the Italian contingent of the Multinational Force in Lebanon. In 1986 the Italian Army abolished the divisional level and the Legnano came under direct command of the 3rd Army Corps. On 30 November 1989 the 68th Mechanized Infantry Battalion "Palermo" was disbanded.[2]
After the end of the Cold War the Italian Army began to draw down its forces and therefore starting in 1991 the Legnano received and lost units repeatedly over the coming years: In June 1991 the brigade received the 4th Tank Battalion "M.O. Passalacqua" and 18th Bersaglieri Battalion "Poggio Scanno" from the disbanded Mechanized Brigade "Goito". The same year the Legnano received the 52nd Field Artillery Group "Venaria" from the disbanded Mechanized Brigade "Brescia", while the 11th Field Artillery Group "Monferrato" was disbanded on 27 August 1991.[3] On 27 August 1992 the 4th Tank Battalion "M.O. Passalacqua" merged with the 67th Mechanized Infantry Battalion "Montelungo" to form the 67th Armored Infantry Regiment "Legnano".[1] In 1993 the brigade provided troops for the United Nations Operation in Somalia II. At the same time the remaining battalions of the brigade returned to use their name regimental names for traditional reasons without changing their composition or size.
In 1995 the Army began a further round of cuts which included the Legnano and so on 5 October 1995 the 67th Armored Infantry Regiment "Legnano" was disbanded.[1] The same year the brigade transferred the 4th Tank Regiment and 52nd Self-propelled Field Artillery Regiment to the Armored Brigade "Centauro", followed in 1996 by the 2nd Bersaglieri and 3rd Bersaglieri regiments.
