Conversely, starting about the mid-19th century, regular cavalry have been forced to spend more of their time dismounted in combat due to the ever-increasing effectiveness of enemy infantry firearms. Thus most cavalry transitioned to mounted infantry. As with grenadiers, the ''dragoon'' and ''cavalry'' designations can be retained long after their horses, such as in the

—basically a folding spade—which can be employed not only to dig important defences, but also in a variety of other daily tasks, and even sometimes as a weapon. Infantry typically have shared equipment on top of this, like tents or heavy weapons, where the carrying burden is spread across several infantrymen. In all, this can reach for each soldier on the march. Such heavy infantry burdens have changed little over centuries of warfare; in the late Roman Republic, legionaries were nicknamed " Marius' mules" as their main activity seemed to be carrying the weight of their legion around on their backs, a practice that predates the eponymous Gaius Marius. When combat is expected, infantry typically switch to "packing light", meaning reducing their equipment to weapons, ammunition, and other basic essentials, and leaving other items deemed unnecessary with their transport or baggage train, at camp or rally point, in temporary hidden caches, or even (in emergencies) simply discarding the items. Additional specialised equipment may be required, depending on the mission or to the particular terrain or environment, including satchel charges,

, exposure, exhaustion and privation—often in excess of the casualties suffered from enemy attacks. Better infantry equipment to support their health, energy, and protect from environmental factors greatly reduces these rates of loss, and increase their level of effective action. Health, energy, and morale are greatly influenced by how the soldier is fed, so militaries issue standardised field rations that provide palatable meals and enough calories to keep a soldier well-fed and combat-ready. Communications gear has become a necessity, as it allows effective command of infantry units over greater distances, and communication with artillery and other support units. Modern infantry can have GPS, encrypted individual communications equipment, surveillance and night vision equipment, advanced intelligence and other high-tech mission-unique aids. Armies have sought to improve and standardise infantry gear to reduce fatigue for extended carrying, increase freedom of movement, accessibility, and compatibility with other carried gear, such as the American all-purpose lightweight individual carrying equipment (ALICE).


Weapons

Infantrymen are defined by their primary arms – the personal weapons and body armour for their own individual use. The available technology, resources, history, and society can produce quite different weapons for each military and era, but common infantry weapons can be distinguished in a few basic categories. * Ranged combat weapons:

Protection

Infantry have employed many different methods of protection from enemy attacks, including various kinds of armour and other gear, and tactical procedures. The most basic is personal armour. This includes shields,
helmets A helmet is a form of protective gear worn to protect the Human head, head. More specifically, a helmet complements the skull in protecting the human brain. Ceremonial or symbolic helmets (e.g., a Custodian helmet, policeman's helmet in the Unite ...

, plate, and kevlar. Initially, armour was used to defend both from ranged and close combat; even a fairly light shield could help defend against most slings and javelins, though high-strength bows and crossbows might penetrate common armour at very close range. Infantry armour had to compromise between protection and coverage, as a full suit of attack-proof armour would be too heavy to wear in combat. As firearms improved, armour for ranged defence had to be made thicker and heavier, which hindered mobility. With the introduction of the heavy arquebus designed to pierce standard steel armour, it was proven easier to make heavier firearms than heavier armour; armour transitioned to be only for close combat purposes. Pikemen armour tended to be just steel helmets and breastplates, and gunners had very little or no armour at all. By the time of the musket, the dominance of firepower shifted militaries away from any close combat, and use of armour decreased, until infantry typically went without wearing any armour. Helmets were added back during World War I as artillery began to dominate the battlefield, to protect against their fragmentation and other blast effects beyond a direct hit. Modern developments in bullet-proof composite materials like kevlar have started a return to body armour for infantry, though the extra weight is a notable burden. In modern times, infantrymen must also often carry protective measures against

Formations

Beginning with the development the first regular military forces, close-combat regular infantry fought less as unorganised groups of individuals and more in coordinated units, maintaining a defined

during combat, for increased battlefield effectiveness; such infantry formations and the arms they used developed together, starting with the spear and the shield. A spear has decent attack abilities with the additional advantage keeping opponents at distance; this advantage can be increased by using longer spears, but this could allow the opponent to side-step the point of the spear and close for

where the longer spear is near useless. This can be avoided when each spearman stays side by side with the others in close formation, each covering the ones next to him, presenting a solid wall of spears to the enemy that they cannot get around. Similarly, a shield has decent defence abilities, but is literally hit-or-miss; an attack from an unexpected angle can bypass it completely. Larger shields can cover more, but are also heavier and less manoeuvrable, making unexpected attacks even more of a problem. This can be avoided by having shield-armed soldiers stand close together, side-by-side, each protecting both themselves and their immediate comrades, presenting a solid shield wall to the enemy. The opponents for these first formations, the close-combat infantry of more tribal societies, or any military without regular infantry (so called " barbarians") used arms that focused on the individual – weapons using personal strength and force, such as larger swinging swords, axes, and clubs. These take more room and individual freedom to swing and wield, necessitating a more loose organisation. While this may allow for a fierce running attack (an initial shock advantage) the tighter formation of the heavy spear and shield infantry gave them a local manpower advantage where several might be able to fight each opponent. Thus tight formations heightened advantages of heavy arms, and gave greater local numbers in melee. To also increase their staying power, multiple rows of heavy infantrymen were added. This also increased their shock combat effect; individual opponents saw themselves literally lined-up against several heavy infantryman each, with seemingly no chance of defeating all of them. ''Heavy infantry'' developed into huge solid block formations, up to a hundred meters wide and a dozen rows deep. Maintaining the advantages of heavy infantry meant maintaining formation; this became even more important when two forces with heavy infantry met in battle; the solidity of the formation became the deciding factor. Intense discipline and training became paramount. Empires formed around their military.


Organization

The organization of military forces into regular military units is first noted in Egyptian records of the
Battle of Kadesh The Battle of Kadesh took place in the 13th century BC between the New Kingdom of Egypt, Egyptian Empire led by pharaoh Ramesses II and the Hittites, Hittite Empire led by king Muwatalli II. Their armies engaged each other at the Orontes River, ...
(). Soldiers were grouped into units of 50, which were in turn grouped into larger units of 250, then 1,000, and finally into units of up to 5,000 – the largest independent command. Several of these Egyptian "divisions" made up an army, but operated independently, both on the march and tactically, demonstrating sufficient military command and control organisation for basic battlefield manoeuvres. Similar hierarchical organizations have been noted in other ancient armies, typically with approximately 10 to 100 to 1,000 ratios (even where

Training

The training of the infantry has differed drastically over time and from place to place. The cost of maintaining an army in fighting order and the seasonal nature of warfare precluded large permanent armies. The antiquity saw everything from the well-trained and motivated citizen armies of Greece and Rome, the tribal host assembled from farmers and hunters with only passing acquaintance with warfare and masses of lightly armed and ill-trained militia put up as a last ditch effort.
