On June 25, 1944, the 3rd Alpini Regiment was recreated in Southern Italy with the battalions Piemonte and Monte Granero. Along with the 4th Bersaglieri Regiment it formed the 1st Italian Brigade of the Italian Liberation Corps, which fought in the war on the Allied side. After the Bersaglieri regiment had suffered heavy casualties the two regiments were merged on 30 September 1944 to form the Special Infantry Regiment, which entered the Legnano Combat Group. The Combat Group was equipped with British weapons and materiel and fought as part of the Polish II Corps on the extreme left of the British 8th Army near the river Idice.
