## History
### Interwar years

On 1 October 1922, the Royal Italian Army formed the 8th Army Corps Engineer Grouping in Santa Maria Capua Vetere. The grouping received a Sappers Battalion and a Telegraphers Battalion, which had been formed on 1 April 1920 for the X Army Corps. On the same date, 1 October 1922, the X Army Corps was renumbered as VIII Army Corps. The grouping also received a miners company from the disbanded Miners Engineer Regiment. After its formation the grouping consisted of a command, a sappers-miners battalion, a telegraphers battalion, which included two dovecotes located in Gaeta and Catanzaro, a photo-electricians company, and a depot. In 1926, the VIII Army Corps was renumbered as X Army Corps and consequently, on 5 November 1926, the grouping was renamed 10th Engineer Regiment. During the same year the dovecote in Catanzaro was disbanded. In February 1928, the regiment ceded some of its personnel to help form the depot of the newly formed 11th Engineer Regiment. On 28 October 1932, the regiment received the IV Radio-Telegraphers Battalion of the disbanded 1st Radio-Telegraphers Regiment.
On 23 September 1935, in preparation for the Second Italo-Ethiopian War, the regiment mobilized the X Replacement Sappers Battalion, which provided 1,300 troops to the 8th Engineer Regiment, which was deployed to Ethiopia for the war. On 15 January 1936, the X Replacements Engineer Battalion was disbanded and its remaining personnel incorporated by the 8th Engineer Regiment. In 1935, the regiment also formed the XXXI, XXXII, XXXIII, and XXXIV engineer battalions for the war, and then in 1936 the XXXIII and XXXVIII engineer battalions. In 1936, the regiment also formed the XX and XXXI marching engineer battalions, whose personnel was intended to replace troops already deployed beyond their service time in East Africa.
At the end of March 1936, the regiment consisted of a command, an engineer battalion, a telegraphers battalion, the dovecote in Gaeta, and a depot. In January 1937, the telegraphers and radio-telegraphers battalions were renamed connections battalions. On 1 January 1937, the regiment's depot in Santa Maria Capua Vetere formed the 20th Engineer Regiment for the XX Army Corps, which was based in the wester part of Libya known as Tripolitania.

During World War II the regiment's depot in Santa Maria Capua Vetere mobilized the following units:

In the evening of 8 September 1943, the Armistice of Cassibile, which ended hostilities between the Kingdom of Italy and the Anglo-American Allies, was announced by General Dwight D. Eisenhower on Radio Algiers and by Marshal Pietro Badoglio on Italian radio. Germany reacted by invading Italy and the 10th Engineer Regiment was disbanded soon thereafter by German forces.
The 4th Engineer Grouping, which was formed on 10 February 1941, left Italy for Albania on 3 March of the same year. The grouping was based in Elbasan and consisted of the IV Telegraphers Battalion, V Cableway Battalion, IX Miners Battalion, XVI Pontieri Battalion, VII Workers Group, XVI Workers Group, and a mobile dovecote. On 1 March 1942, the grouping was reorganized and consisted afterwards of the V Telegraphers Battalion, VI Marconisti Battalion, XII Miners Battalion, and VII Workers Group. After the announcement of the Armistice of Cassibile the grouping was disbanded by German forces. The XL Workers Group served with the Italian 8th Army on the Eastern Front. In December 1942, most of the 8th Army was destroyed during the Soviet Operation Little Saturn. For its conduct and sacrifice on the Eastern Front the XL Workers Group was awarded a War Cross of Military Valor, which was affixed to the regiment's flag.

### Cold War

On 1 April 1953, the Italian Army formed the III Army Corps Engineer Battalion in Pavia in Lombardy by expanding the existing 3rd Territorial Engineer Company. The battalion was assigned to the III Army Corps and, on 1 June 1953, formed a command platoon and the 2nd Engineer Company. In November 1953, the battalion completed its organization with the formation of the Field Park Company.
During the 1975 army reform, the army disbanded the regimental level and newly independent battalions were granted for the first time their own flags. During the reform engineer battalions were named for a lake, if they supported an corps-level command, or a river, if they supported a division or brigade. On 10 October 1975, the III Army Corps Engineer Battalion was renamed 3rd Engineer Battalion "Lario". The battalion was named for the great pre-alpine Lake Como, which is also known as Lake Lario, and located in Lombardy. After the reform the 3rd Engineer Battalion "Lario" consisted of a command, a command and park company, and three engineer companies. At the time the battalion fielded 756 men (38 officers, 98 non-commissioned officers, and 620 soldiers).
On 12 November 1976, the President of the Italian Republic Giovanni Leone assigned with decree 846 the flag and traditions of the 10th Engineer Regiment to the battalion. On 1 January 1987, the Command and Park Company split into the Command and Services Company and the Special Equipment Company. Afterwards the battalion consisted of the following units:
* 3rd Engineer Battalion "Lario", in Pavia
** Command and Services Company
** 1st Engineer Company
** 2nd Engineer Company
** 3rd Engineer Company
** Special Equipment Company
