The regiment is the only military unit which has participated in all out-of-area missions of the Italian Army since World War II.

[6][7][8] During World War I the Royal Italian Army formed assault units manned by Arditi troops to storm enemy trenches in close combat.

In 1942, during World War II, the Royal Italian Army formed the 10th Arditi Regiment, whose personnel operated behind allies lines in North Africa.

In September 1943, after the announcement of the Armistice of Cassibile the regiment's I Arditi Battalion, which was based in Sardinia and undertook reconnaissance, intelligence gathering, and sabotage missions in allied held Algeria and Tunisia, joined the Italian Co-belligerent Army.

In 1995, the battalion lost its autonomy and entered the newly formed 9th Paratroopers Assault Regiment "Col Moschin".

In 2014, the regiment was transferred from the Paratroopers Brigade "Folgore" to the newly formed Army Special Forces Command.

After the disastrous Battle of Caporetto the Royal Italian Army added a flamethrower section to each assault company.

On 16 June, the IX Assault Unit was ordered to retake the Italian positions on the summit of Col Moschin, which had been lost the day before on.

The IX Assault Unit retook the position in a lightning attack and held the summit until Italian infantry could be brought up.

Advanced training for the paratroopers occurred at the Royal Italian Air Force's Paratroopers School Tarquinia, while advanced training for the swimmers occurred at the Royal Italian Navy's Divers School in Livorno and at the naval base in Pula.

Before the battalion left mainland Italy for Sardinia both companies detached two patrols, which were sent to the island of Rhodes and intended to operate against British forces in Cyprus.

[8] On 10 June 1943, the 10th Arditi Regiment was reorganized and three special companies were formed, which consisted of personnel capable of operating behind enemy lines in civilian clothes.

[8] The first operation of the regiment occurred during the night of 16 to 17 January 1943, when a patrol of the 101st Paratroopers Company parachuted into Algeria on an intelligence gathering mission.

From January to July 1943 the regiment undertook twenty air or sea assaults against railway bridges, airfields, and other objects in Algeria, Tunisia, or Libya.

In the evening of 30 July 1943, the 4th Patrol of the 112th Landing Company embarked at Giardini Naxos on three assault boats of the Royal Italian Navy.

On 20 March 1944, the I Arditi Battalion was renamed IX Assault Unit and assigned to the Italian Co-belligerent Army's I Motorized Grouping.

For its conduct in these battles the IX Assault Unit was awarded a second Silver Medal of Military Valor.

[6][1][8][11] On 24 September 1944, the IX Assault Unit entered the 68th Infantry Regiment "Legnano" as III Battalion "Col Moschin".

For its conduct in these battles the III Battalion "Col Moschin" was awarded the unit's third Silver Medal of Military Valor.

[8][11] On 20 April 1953, the Italian Army's Infantry School in Cesano formed a Paratroopers Saboteurs Company.

[6][1][4] From July 2006 to October 2009, the regiment maintained a permanent presence in Kabul in Afghanistan as part of the NATO-led International Security Assistance Force.

[1][5] On 19 September 2014, the regiment was transferred from the Paratroopers Brigade "Folgore" to the newly formed Army Special Forces Command.
