In March 1941 the division and regiment were sent to Libya for the Western Desert campaign, during which both were destroyed in the Second Battle of El Alamein in November 1942.
In 1975 the unit was reformed as 46th Field Artillery Group "Trento" and assigned to the Mechanized Brigade "Gorizia". In 1991 the group was disbanded and its personnel, materiel, and base were assigned to the 184th Self-propelled Field Artillery Group "Filottrano". The regimental anniversary falls, as for all Italian Army artillery regiments, on June 15, the beginning of the Second Battle of the Piave River in 1918.

During the Eighth Battle of the Isonzo the regiment was deployed at Nova Vas and Hudi Log. From May to August 1917 the regiment was deployed on Monte Vodice, Monte Kuk and Monte Jelenik. During the Second Battle of the Piave River in June 1918 the regiment was positioned near Fornaci and Case Ninni. In July 1918 the regiment was transferred to the Tonale Pass. During the decisive Battle of Vittorio Veneto the regiment was deployed on the Monte Pertica in the Monte Grappa massif and advanced to the Monte Prassolan from there to Fonzaso, where the news of the Armistice of Villa Giusti reached the regiment.
