Known as the “Queen of Battle,” the infantry is the branch of the army that provides its primary fighters. The main responsibility of infantry soldiers is to “close with and destroy the enemy.” Although they are trained, armed and equipped to fight on foot, infantry soldiers are usually transported to the battlefield by other means. Infantry soldiers can also specialize as light, mechanized, airmobile, airborne and other types. The characteristics of infantry are mobility, firepower, flexibility, communications and vulnerability (to enemy action). Infantry soldiers are trained in a wide range of individual and crew-served weapons and work with the all-arms team of reconnaissance, armour, artillery, air defence, engineers, tactical aviation and other combat specialists. Except for a brief time during the feudal period (when cavalry dominated), the infantry has been the largest single component of armies since ancient times. In Canada, the infantry has always been the army’s largest element.
