Arditi

Arditi was the name adopted by Royal Italian Army elite storm troops of World War I. The name derives from the Italian verb ardire ("to dare") and translates as "The Daring Ones".
Reparti d'assalto (Assault Units) were formed in the summer of 1917 by Colonel Bassi, and were assigned the tactical role of shock troops, breaching enemy defenses in order to prepare the way for a broad infantry advance. The Arditi were not units within infantry divisions, but were considered a separate combat arm.
