The 2nd Alpine Signal Regiment () is a deployable signals regiment of the Italian Army based in Bolzano in South Tyrol that specializes in mountain warfare. Since 1951 it has been assigned of the 4th Alpine Army Corps and therefore a strong association with the army's mountain infantry corps, the Alpini, with whom the regiment shares the distinctive Cappello Alpino. The unit was first active from 1926 to 1932 as 2nd Radio-Telegraphers Regiment.
The unit was reformed in 1951 as a battalion and given the number IV, which had been used by two battalions active during World War II. During the Cold War the battalion was assigned to the IV Army Corps. In 1975 the battalion was named for the Gardena Pass and assigned the flag and traditions of the 2nd Radio-Telegraphers Regiment. In 1992 the battalion entered the newly formed 2nd Signal Regiment. In 2001 the regiment reformed the Battalion "Pordoi" as its second signal battalion. The regiment is assigned to the army's Signal Command and affiliated with the Alpine Troops Command.
History
On 15 November 1926 the Radio-Telegraphers Engineer Regiment was split and the next day the 2nd Radio-Telegraphers Regiment was formed in Florence, which received the II, IV, and V battalions from the Radio-Telegraphers Engineer Regiment. After the split the 2nd Radio-Telegraphers Regiment formed two new battalions and then consisted of a command, the I, III, and V battalions in Milan, the II Battalion in Mestre, the IV Battalion in Alessandria, a depot in Florence, and two branch depots in Piacenza and Mantova. Each of the five battalions consisted of two companies. In 1930 the regiment moved from Florence to Novi Ligure.
On 28 October 1932 both radio-telegraphers regiments were disbanded and the units of the 2nd Radio-Telegraphers Regiment were distributed among the army's engineer regiments as follows:
I Battalion -> 2nd Engineer Regiment
II Battalion -> 3rd Engineer Regiment
III Battalion -> 1st Engineer Regiment
7th Company/ IV Battalion -> 4th Engineer Regiment
8th Company/ IV Battalion -> 5th Engineer Regiment
V Battalion -> 11th Engineer Regiment
The 2nd Radio-Telegraphers Regiment depot and depot personnel were used to from the 1st Miners Regiment.
Cold War
On 20 August 1951 the IV Connections Battalion was formed in Bolzano as support unit of the IV Territorial Military Command. Due to its number the battalion became the spiritual successor of the IV Telegraphers Battalion, which had been formed by the 10th Engineer Regiment during World War II, and also of the IV Army Connections Battalion, which had been formed by the 5th Engineer Regiment during the same conflict. On 1 October 1952 the Connections Speciality became an autonomous speciality of the Engineer Arm, with its own school and gorget patches. On 16 May 1953 the speciality adopted the name Signal Speciality and consequently the IV Connections Battalion was renamed IV Signal Battalion on the same date. In January 1954 the battalion was renamed IV Army Corps Signal Battalion and consisted of a command, an operations company, a line construction company, and a signal center. In 1967 the battalion formed a second line construction 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 signal battalions were renamed for mountain passes. On 1 October 1975 the IV Army Corps Signal Battalion was renamed 4th Signal Battalion "Gardena" and assigned the flag and traditions of the 2nd Radio-Telegraphers Regiment. The battalion consisted of a command, a command and services platoon, three signal companies, and a repairs and recovery platoon.
On 22 January 1976 the battalion's troops received the Cappello Alpino. On 21 March 1976 the flag of the 2nd Radio-Telegraphers Regiment arrived in Bolzano and was transferred to the custody of the battalion. In 1978 the battalion was ordered to form a fourth signal company in Bolzano, but due to a lack of lodgings the company was only activated and staffed in December 1984.
