Infantry: the story on HearLore | HearLore
Infantry
The word infantry entered English usage around the 1570s to describe soldiers who marched and fought on foot. This term derives from Middle French infanterie, which traces back to older Italian and Spanish forms meaning foot soldiers too inexperienced for cavalry work. The root Latin word īnfāns means without speech or newborn, sharing its origin with the modern word infant. Individual soldiers did not receive the specific title infantryman until 1837 when that designation finally appeared in print.
Some military forces like the Canadian Army prefer the term infanteer instead of infantryman to refer to an individual soldier within the branch. From the mid-18th century through 1881, the British Army named its units as numbered regiments of Foot to distinguish them clearly from cavalry and dragoon regiments. Infantry equipped with special weapons often adopted names based on those tools, such as grenadiers for their grenades or fusiliers for their fusils.
These historical designations persist long after the original weapon specialty disappears. Examples include the Royal Irish Fusiliers and the Grenadier Guards, which retain their names despite no longer using the weapons that defined them originally. Dragoons were created as mounted infantry with horses for travel between battles but still dismounted before combat began.
Historical Evolution Of Combat
The first military forces in history consisted entirely of infantry armed with early melee weapons like spears, axes, or swords. Ranged options included javelins, slings, or bows, with some soldiers expected to use both types simultaneously. Gunpowder development eventually converted infantry to primarily firearms by the time of Napoleonic warfare. During that era, infantry, cavalry, and artillery formed a basic triad of ground forces while infantry remained the most numerous component.
Armored fighting vehicles later replaced horses for cavalry roles, yet airpower added new dimensions to ground combat without diminishing infantry's pivotal status. The earliest warriors likely started as loose groups without organization before organized empires emerged between 2500 and 1500 BC. These ancient states required standardized equipment plus training and discipline for battlefield formations and maneuvers.
Regular infantry forces usually stayed small due to high costs of training and upkeep. They often supplemented local short-term mass-conscript forces using older irregular infantry weapons and tactics. This practice remained common almost up to modern times. Before chariots created mobile fighting forces, all armies were pure infantry. Even after their invention, infantry has been the largest component of most armies throughout history except for rare exceptions like the Mongol Empire.

Which ancient empire first recorded organized military forces into regular units?
The organization of military forces into regular units first appears in Egyptian records of the Battle of Kadesh. Soldiers grouped into units of 50 which then formed larger units of 250, 1,000, and finally up to 5,000 as largest independent commands.
What equipment do infantrymen carry to reduce heavy burdens during marches?
An infantryman's military kit generally includes combat boots, battledress or combat uniform, camping gear, heavy weather gear, survival gear, secondary weapons, ammunition, weapon service kits, health items, mess kits, rations, filled water canteens, and other consumables needed for operating away from base units. One of the most valuable pieces of gear is the entrenching tool, a folding spade used to dig defenses or perform daily tasks.

One of the most valuable pieces of gear is the entrenching tool, a folding spade used to dig defenses or perform daily tasks. Sometimes this tool serves even as a weapon itself.
Infantry typically share equipment like tents or heavy weapons where carrying burdens spread across several soldiers. Total weight can reach significant amounts for each soldier on the march. Such heavy burdens have changed little over centuries of warfare since Roman legionaries earned nicknames like Marius' mules for carrying their legion around on their backs. When combat expected, infantry switch to packing light by reducing equipment to weapons, ammunition, and basic essentials only.
Additional specialized equipment may include satchel charges, demolition tools, mines, or barbed wire depending on mission requirements or terrain conditions. Historically, high casualty rates resulted from disease, exposure, exhaustion, and privation often exceeding losses from enemy attacks directly. Better equipment supporting health, energy, and environmental protection greatly reduces these loss rates while increasing effective action levels.
Weapons And Protection Systems
Infantrymen are defined by primary arms including personal weapons and body armor for individual use. Available technology, resources, history, and society produce quite different weapons for each military and era yet common categories exist. Ranged combat weapons span javelins, slings, blowguns, bows, crossbows, hand cannons, arquebuses, muskets, grenades, and flamethrowers. Melee options include bludgeoning clubs, flails, maces, bladed swords, dagges, axes, polearms like spears, halberds, naginata, and pikes.
The bayonet fixed to a firearm allows infantrymen to use the same weapon for both ranged and close combat starting with muskets. This practice continues today with modern assault rifles though usage has declined since automatic firearms introduced themselves. Infantry often carry secondary sidearms sometimes called ancillary weapons for possible hand-to-hand combat situations. The pilum was a javelin Roman legionaries threw just before drawing their primary gladius short sword to close with enemy lines.
Modern infantry treat bayonets as backup weapons but may also deploy handguns as sidearms or anti-personnel mines defensively before combat begins. Personal armor includes shields, helmets, padded linen, leather, lamellar, mail, plate, and Kevlar materials initially defending against both ranged and close attacks. Heavy arquebus designs proved easier to make heavier than heavy armor itself leading to armor transitioning only for close combat purposes.
Tactical Formations And Doctrine
Close-combat regular infantry fought less as unorganized groups of individuals and more in coordinated units maintaining defined tactical formations during combat. Such infantry formations developed together with arms starting from spear and shield combinations. A spear offers decent attack abilities while keeping opponents at distance longer. Longer spears increase this advantage yet allow opponents to side-step points for hand-to-hand combat where length becomes useless.
Shield-armed soldiers stand close together side-by-side each protecting themselves and immediate comrades presenting solid shield walls to enemies. Opponents using personal strength focused weapons like swinging swords, axes, and clubs necessitate looser organization requiring more room and individual freedom. Tighter formations give heavy spear and shield infantry local manpower advantages where several might fight each opponent simultaneously. Multiple rows added staying power increasing shock combat effects dramatically.
Heavy infantry developed into huge solid block formations up to hundred meters wide and dozen rows deep. Maintaining formation advantages became even more important when two forces met in battle since formation solidity decided outcomes. Intense discipline and training became paramount as empires formed around their military capabilities. The Roman testudo performed during sieges demonstrated how tightly packed shields created impenetrable defensive barriers against projectiles.
Organizational Structures And Training
The organization of military forces into regular units first appears in Egyptian records of the Battle of Kadesh. Soldiers grouped into units of 50 which then formed larger units of 250, 1,000, and finally up to 5,000 as largest independent commands. Several Egyptian divisions made up armies yet operated independently both on march and tactically demonstrating sufficient command control for basic maneuvers. Similar hierarchical organizations exist in other ancient armies typically with ratios approximately 10 to 100 to 1,000 resembling modern sections, companies, and regiments.
Training differed drastically over time and place due to costs maintaining fighting orders plus seasonal warfare nature precluding large permanent armies. Antiquity saw well-trained citizen armies from Greece and Rome alongside tribal hosts assembled from farmers and hunters with only passing acquaintance with warfare. Kushite king Taharqa enjoyed success in the Near East through daily long-distance running training efforts strengthening his army. Medieval foot soldiers varied from peasant levies to semi-permanent mercenary companies including Swiss, English, Aragonese, and German groups.
Men-at-arms fought on foot as well-armored as knights sometimes while standing armies increased training and experience levels. National mass armies established minimum requirements introducing special troops like engineers going back to medieval times plus different infantry types adapted to specific terrain. Bicycle, motorcycle, motorized, and mechanized troops culminated with highly trained special forces during first and second World Wars.
