In World War I the regiment's groups and batteries served on the Italian front.

The Alpine Brigade "Julia" is a light infantry brigade of the Italian Army, specializing in mountain warfare. Its core units are Alpini, an infantry corps of the Italian Army, that distinguished itself during World War I and World War II. The brigade carries on the name and traditions of the 3rd Alpine Division "Julia". The division's and brigade's name allude to the Julian Alps in the Friuli region where the division's regiments recruited their troops, and where after World War II the brigade was based. Accordingly, the brigade's coat of arms is modeled after the Friuli region's coat of arms.
