The 2nd Heavy Field Artillery Regiment (Italian: 2° Reggimento Artiglieria Pesante Campale) is an inactive artillery regiment of the Italian Army, which was based in Barletta in Apulia and assigned to the Mechanized Brigade "Pinerolo".

The regiment and its groupings were disbanded by invading German forces after the announcement of the Armistice of Cassibile on 8 September 1943.

[1] This article is about the Royal Italian Army's 2nd Heavy Field Artillery Regiment, which was a support unit assigned to a corps-level command.

In 1935 the regiment provided four officers and 117 enlisted to augment units deployed for the Second Italo-Ethiopian War.

[1] At the outbreak of World War II the regiment consisted of a command and four groups.

The depot was disbanded by invading German forces after the announcement of the Armistice of Cassibile on 8 September 1943.

The grouping was heavily attrited in the fighting and the survivors were evacuated to mainland Italy, and sent to the depot of the 2nd Army Corps Artillery Regiment to help form the 236th Self-propelled Anti-tank Regiment for the 136th Armored Legionary Division "Centauro".

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 II Group in Barletta became an autonomous unit and was renamed 2nd Heavy Field Artillery Group "Potenza".

The group was named for the city of Potenza in southern Italy and assigned the flag and traditions of the 2nd Heavy Field Artillery Regiment.

[1][2] On 12 November 1976 the President of the Italian Republic Giovanni Leone assigned with decree 846 the flag and traditions of the 2nd Heavy Field Artillery Regiment to the group.

In 1993 the 2nd Field Artillery Group "Potenza" received M109G 155 mm self-propelled howitzers and on 14 October of that year the group lost its autonomy and entered the next day the 2nd Self-propelled Field Artillery Regiment "Potenza".
