Etymology

The word "armour" came into use in the Middle Ages as a borrowing from the French. It is dated from 1297, as a "mail, defensive covering worn in combat" from Old French armeure, itself derived from the Latin armatura "arms and/or equipment" with the root arma "arms or gear".

History

Significant factors in the development of armour include the economic and technological necessities of armour production. For instance, plate armour first appeared in Medieval Europe when water-powered trip hammers made the formation of plates faster and cheaper. Also, modern militaries usually do not equip their forces with the best armour available, since it would be prohibitively expensive. At times the development of armour has run parallel to the development of increasingly effective weaponry on the battlefield, with armourers seeking to create better protection without sacrificing mobility.

 constructed from iron plates connected together by leather thongs. Japanese lamellar armour (keiko) passed through Korea and reached Japan around the 5th century. These early Japanese lamellar armours took the form of a sleeveless jacket and a helmet.

Armour did not always cover all of the body; sometimes no more than a helmet and leg plates where worn. The rest of the body was generally protected by means of a large shield. Examples of armies equipping their troops in this fashion were the Aztecs (16th century DC), and the hoplites in Ancient Greece.

By about 1400 the full harness of plate armour had been developed in armouries of Lombardy Heavy cavalry dominated the battlefield for centuries in part because of their armour.

In the early 15th century, advances in weaponry allowed infantry to defeat armoured knights on the battlefield. The quality of the metal used in armour deteriorated as armies became bigger and armour was made thicker, necessitating breeding of larger cavalry horses. If during the 14–15th centuries armour seldom weighed more than 15 kg, then by the late 16th century it weighed 25 kg. The increasing weight and thickness of late 16th century armour therefore gave substantial resistance.

In the early years of low velocity firearms, full suits of armour, or breast plates actually stopped bullets fired from a modest distance. Crossbow bolts, if still used, would seldom penetrate good plate, nor would any bullet unless fired from close range. In effect, rather than making plate armour obsolete, the use of firearms stimulated the development of plate armour into its later stages. For most of that period, it allowed horsemen to fight while being the targets of defending arquebuseers without being easily killed. Full suits of armour were actually worn by generals and princely commanders right up to the second decade of the 18th century. It was the only way they could be mounted and survey the overall battlefield with safety from distant musket fire.

. This gave the horse protection and enhanced the visual impression of a mounted knight. Late in the era, elaborate barding was used in parade armour.

Later

Gradually starting in the mid-16th century, one plate element after another was discarded to save weight for foot soldiers.

Back and breast plates continued to be used throughout the entire period of the 18th century and through Napoleonic times, in many European (heavy) cavalry units, until the early 20th century. From their introduction, muskets could pierce plate armour, so cavalry had to be far more mindful of the fire. In Japan armour continued to be used until the end of the samurai era, with the last major fighting in which armour was used happening in 1868.Samurai armour had one last short lived use in 1877 during the Satsuma Rebellion

Though the age of the knight was over, armour continued to be used in many capacities. Soldiers in the American Civil War bought iron and steel vests from peddlers (both sides had considered but rejected body armour for standard issue). The effectiveness of the vests varied widely- some successfully deflected bullets and saved lives, but others were poorly made and resulted in tragedy for the soldiers. In any case the vests were abandoned by many soldiers due to their weight on long marches as well as the stigma they got for being cowards from their fellow troops.

The US Army has adopted Interceptor body armour, which uses Enhanced Small Arms Protective Inserts (E-S.A.P.I) in the chest, sides and back of the armour. Each plate is rated to stop a range of ammunition including 3 hits from a 7.62×51 NATO AP round at a range of 10 m (33 ft), though accounts in Iraq and Afghanistan tell of soldiers shot as many as seven times in the chest without penetration. Dragon Skin body armour is another ballistic vest which is currently in testing with mixed results.

Despite advances in the protection offered by ballistic armour against projectiles, as the name implies, modern ballistic body armour is much less impervious to stabbing weapons unless they are augmented with anti-knife/anti-stab armour (usually a form of mail

The rapid evolution of warship design in the late 19th century transformed the ironclad from a wooden-hulled vessel which carried sails to supplement its steam engines into the steel-built, turreted battleships and cruisers familiar in the 20th century. This change was pushed forward by the development of heavier naval guns (the ironclads of the 1880s carried some of the heaviest guns ever mounted at sea), more sophisticated steam engines, and advances in metallurgy which made steel shipbuilding possible.

The rapid pace of change in the ironclad period meant that many ships were obsolete as soon as they were complete, and that naval tactics were in a state of flux. Many ironclads were built to make use of the ram

s, supported by infantry. Tanks were knocked out on both sides, but the German attack failed and they retreated.

Mechanical problems, poor mobility and piecemeal tactical deployment limited the military significance of the tank in World War I and the tank did not fulfil its promise of rendering trench warfare obsolete. Nonetheless, it was clear to military thinkers on both sides that tanks would play a significant role in future conflicts.

Aircraft

The development of effective anti-aircraft artillery before the Second World War meant that the pilots, once the "knights of the air" during the First World War were left far more vulnerable to ground fire. This not only created the requirement for the introduction of the cockpit armour plating that eventually came to be known variously as the "bucket" or the "bathtub", but also the design of such aircraft as the Il-2

 which also were heavily armoured to protect the fuel and engine, allowing much greater survivability during ground assaults.

Tank armour has progressed from the Second World War armour forms, now incorporating not only harder composites
