In short: During World War I, the Italian Army formed the Arditi, an elite force designed to breach enemy lines through aggressive shock tactics. Armed with daggers and grenades, these soldiers abandoned traditional infantry roles to spearhead assaults, forever changing the nature of combat on the Italian Front before their 1920 demobilization.

The Arditi, whose name translates as The Daring Ones, emerged from the tactical frustrations of the Great War. By 1916, Italian commanders like Major General Francesco Grazioli and Major Giuseppe Bassi sought to overcome the bloody stagnation of trench warfare. They envisioned small, highly mobile units trained specifically for hand-to-hand combat and trench clearing. These soldiers were equipped with Carcano carbines, hand grenades, and the Villar Perosa machine-pistol, a weapon Bassi modified to increase mobility by removing heavy shields and adding bipods.

The official birth of the Arditi occurred on July 29, 1917, with the formation of the 1st Assault Battalion. Unlike standard infantry, these units were independent branches within the Italian Infantry Arm. They were easily identified by their distinctive uniforms, which featured open-collar cyclist tunics and flame-shaped collar tabs—black for infantry, crimson for Bersaglieri, and green for Alpine troops. Their baptism of fire came during the Eleventh Battle of the Isonzo in August 1917, where they were deployed to capture strategic points like the town of Loga and the summit of Mount San Gabriele.

While the Arditi achieved tactical successes, their operations were often hampered by a lack of reinforcements and supplies. During the assault on Mount San Gabriele in September 1917, they successfully cleared the summit but were forced to retreat after sustaining heavy losses and failing to receive support. Despite their battlefield prowess, the units were demobilized by 1920. However, their legacy persisted; the name was later adopted by Gabriele D'Annunzio’s occupiers of Fiume and eventually influenced the 10th Arditi Regiment of 1942. Today, the tradition continues through the 9th Paratroopers Assault Regiment Col Moschin, whose operatives are still known as Arditi Incursori.

The Arditi were distinct from earlier special units like the Compagnie della morte, which were primarily sappers tasked with cutting barbed wire. While the Supreme Command initially used the term Militare ardito to badge soldiers for bravery, the true Arditi represented a fundamental shift toward specialized shock troops. Their tactics, training, and equipment were specifically engineered for the confined, violent reality of trench warfare, marking them as one of the first modern examples of elite special forces.
