[2] This article is about the Royal Italian Army's 11th Heavy Field Artillery Regiment, which was a support unit assigned to a corps-level command.
The regiment consisted of a depot and four groups, which had fought in World War I on the Italian front.
The depot was disbanded by invading German forces after the announcement of the Armistice of Cassibile on 8 September 1943.
On 30 September 1976 the 9th Heavy Field Artillery Regiment in Foggia was disbanded and the next day, on 1 October 1976, the regiment's III Group in Persano became an autonomous unit and was renamed 11th Heavy Field Artillery Group "Teramo".
The group was named for the city of Teramo in southern Italy and assigned the flag and traditions of the 11th Heavy Field Artillery Regiment.

In 1992 the 11th Field Artillery Group "Teramo" received M109G 155 mm self-propelled howitzers and on 10 September of that year the group lost its autonomy and entered the next day the 11th Self-propelled Field Artillery Regiment "Teramo".
