Formation On 1 March 1915 the 151st Infantry Regiment (
Brigade "Sassari") was formed in
Sinnai near
Cagliari in the South of Sardinia. On the same date the
152nd Infantry Regiment (Brigade "Sassari") and the command of the Brigade "Sassari" were formed in
Tempio Pausania near
Sassari in the North of
Sardinia. The brigade consisted of personnel levied in Sardinia by the following pre-war regiments: •
45th Infantry Regiment (
Brigade "Reggio") in Tempio Pausania: Command of the Brigade "Sassari" and 152nd Infantry Regiment •
46th Infantry Regiment (Brigade "Reggio") in Sinnai: 151st Infantry Regiment Each regiment consisted of three battalions, which each fielded four
fusilier companies and one machine gun section. The Brigade "Sassari" formed, together with the
Brigade "Macerata", the 25th Division. In June 1917 the brigade attacked
Austro-Hungarian positions on
Monte Zebio and in September the brigade was back in the East on the
Banjšice plateau for the
Eleventh Battle of the Isonzo. After the Italian defeat in the
Battle of Caporetto the brigade fought delaying actions at
Buttrio and on the
Monticano river from 27 October to 8 November. From 10 December 1917 the brigade was back on the Sette Comuni plateau.
World War II officer negotiating with German paratroopers during the fighting in Rome in 1943 At the outbreak of
World War II the regiment consisted of a command, a command company, three
fusilier battalions, a support weapons battery equipped with
65/17 infantry support guns, and a mortar company equipped with
81mm Mod. 35 mortars. On 6 April 1941 the division participated in the
invasion of Yugoslavia and for the next two years the division's command was based in
Knin, while the division's units were employed in anti-
partisan operations in the surrounding area. In March 1943, after the
Battle of the Neretva, the division was transferred to
Rome to defend the city in case of an
allied attack. The battalions remained assigned to the Sardinia Military Command and continued to train recruits. To avoid confusion with the 152nd Infantry Battalion "Sassari" the 151st Infantry Battalion's name was changed from "Sassari" to "
Sette Comuni" to commemorate the location, where the two regiments had earned their first
Gold Medal of Military Valor. On 1 December 1988 the battalion was assigned to the reformed
Motorized Brigade "Sassari".
Recent times On 31 December 1991 the battalion was reorganized as a mechanized unit and consisted now of a command, a command and services company, three mechanized companies equipped with
M113 armored personnel carriers, and a heavy mortar company equipped with
M106 mortar carriers with 120mm Mod. 63 mortars. On 22 July 1992 the 151st Mechanized Infantry Battalion "Sette Comuni" lost its autonomy and the next day the battalion entered the reformed 151st Infantry Regiment "Sassari" as I Mechanized Battalion. On 21 May 2025, the regiment was awarded the Silver Medal of Army Valor for its conduct during its deployment to
Lebanon as part of the
United Nations Interim Force in Lebanon from August 2024 to February 2025, which coincided with the
Hezbollah–Israel conflict that had started in October 2023. == Organization ==
