TheGuardia alla Frontiera (GaF) (transl. "border guard"), was anRegio Esercitoborder guard created in 1937[1] who defended the 1,851 km of northern Italian frontiers with the "Vallo Alpino Occidentale" (487 km withFrance), "Vallo Alpino Settentrionale" (724 km withSwitzerland and 420 km withAustria) and "Vallo Alpino Orientale" (220 km withYugoslavia).
In 1940, the GaF had 21,000 military personnel, deployed in eight commands, 27 sectors, and seven regiments of artillery. It manned 1,000 fortifications, 6,000 machine guns, 1,000 mortars, 100Cannone da 47/32 M35, and another thousand other medium and small-caliber cannons (75/27 and149/35).
By 10 June 1940 (Italy's entry into the war) the GaF (not counting colonies in Libya and Albania) contained 23 sectors, 50,000 men, 28 battalions "Vallo Alpino", and 22 battalions offascist militia.
Each command of the army of GaF could be divided into "sectors" (27 areas of coverage, from I to XXVII, along the border; sectors XVIII, XIX and XX were never realized), which could be broken down into subsectors and so on for ever smaller units. Each command in the field had two or more subsectors which controlled the fortifications. These works were manned by infantry, artillery, engineers, etc. Despite the GaF being predominantly static it also received five light tank (carristi) companies, equipped withFiat 3000 tanks that over time, due to their age and lack of spare parts, ended largely abandoned in Sector armories or buried to use the turrets as a fort.
The Guardia alla Frontiera disappeared after 1943, but nominally was active until 1953.[2]
