Infantry

Infantry is the branch of an army that fights on foot. Infantrymen are land-based soldiers who are specifically trained for the role of fighting on foot to engage the enemy face-to-face and have historically borne the brunt of the casualties of combat in wars. As the oldest branch of combat arms, they are still the backbone of modern armies. Infantry units have more physically-demanding training than other branches of armies, and place a greater emphasis on discipline, physical strength, fitness and spontaneous sustained aggression. The infantryman himself, with or without his personal weapon, is considered a weapon system.
Infantrymen are easily distinguished from soldiers trained to fight on horseback (cavalry), in tanks, or in technical roles such as armourers or signallers. Rudimentary infantry skills such as basic individual movement techniques, shooting positions and field craft are fundamental to the training of every soldier
. Infantry can access and maneuver in terrain inaccessible to vehicles and tanks, and employ infantry support weapons that can provide firepower in the absence of artillery. Their combat insertion techniques include, airborne, air assault, amphibious and by land.
