After the announcement of the Armistice of Cassibile on 8 September 1943 the regiment was disbanded by invading German forces.

[3][4][5] The regiment's anniversary falls, as for all engineer units, on 24 June 1918, the last day of the Second Battle of the Piave River.

After the end of World War I the Royal Italian Army reorganized its forces and on 31 March 1920, the 7th Engineer Regiment (Telegraphers) was disbanded.

[1] In April 1923, one of the regiment's sappers-miners companies moved to Ozieri in Sardinia and established a detachment, which in May 1923 was transferred to the 7th Army Corps Engineer Grouping.

Germany reacted by invading Italy and the 7th Engineer Regiment was disbanded soon thereafter by German forces.

[1] On 1 October 1944, the Italian Co-Belligerent Army formed the CIV Mixed Engineer Battalion in Cosenza, which was assigned to the Combat Group "Mantova".

Both companies were transferred from the 104th Infantry Division "Mantova", which had remained loyal to King Victor Emmanuel III after the announcement of the Armistice of Cassibile.

[1] After the end of the war the CIV Mixed Engineer Battalion was based in Albissola and remained assigned to the Combat Group "Mantova".

[7] On 12 November 1976, the President of the Italian Republic Giovanni Leone assigned with decree 846 the flag and traditions of the 7th Engineer Regiment to the battalion.

Consequently, on 30 September 1986, the command of the Mechanized Division "Mantova" was disbanded, followed by the 104th Engineer Battalion "Torre" on 31 October 1986.

Consequently, on 1 January 2002, the Italian Army formed the CIMIC Group South in Motta di Livenza.

After becoming operational, the CIMIC Group South was assigned to NATO's Supreme Allied Commander Europe.

The regiment is assigned to the Tactical Intelligence Brigade and part of the NATO Response Force.
