Italian tank battalions were classed as either light or medium. In 1940 a standard Italian tank battalion usually contained three tank companies and a battalion HQ. A battalion HQ had only one or two tanks plus a couple of reserve vehicles. Tank companies were generally made up of three platoons and a small CHQ, each medium platoon had five tanks plus one issued to the platoon HQ, a light platoon contained four. A battalion could hold up to five tank companies, but three was standard and the tank strength could range from 40 to 55 tanks.
