102-397: Historically, the range of artillery steadily increased over the centuries. In the era of bombards or Steinbüchse , the gunner could usually still fire directly on the target by line-of-sight. As ranges increased, methods of employing indirect fire were developed. This made a forward observer essential in order to be able to use artillery effectively. The proximity of the observer to

204-538: A Fire Support Officer (FSO), Forward Air Controller (FAC) or Joint Terminal Attack Controller (JTAC), two scout observers (FO), and two radio operators (RO). In Weapons Company, the Fire Support Coordination Center (FSCC) determines fire support asset allocation to each rifle company FiST, and supervises the planning and execution of each FiST's fire support plan. Key players in the FSCC include

306-555: A Fire support specialist in the grade of E-1 to E-4 and a Fire Support Sergeant in the grade of E-5. Currently in unit training is beginning to incorporate more close air support and close combat attack missions into the field artillery team's mission. In the U.S. Marine Corps, scout observers also act as naval gunfire spotters and call for, observe and adjust artillery and naval gunfire support , and coordinate fire support assets to include mortars, rockets, artillery, NSFS and CAS/CIFS. A rifle company Fire Support Team typically consists of

408-399: A better method of indirect laying (instead of aiming points in line with the target). In essence, this was the geometry of using angles to aiming points that could be in any direction relative to the target. The problem was the lack of an azimuth instrument to enable it; clinometers for elevation already existed. The Germans solved this problem by inventing the lining-plane in about 1890. This

510-493: A company or squadron of a battalion or regiment that their battery was supporting. In the British artillery system FOOs were always authorized to order fire commands to their own troop or battery, based on their assessment of the tactical situation and if necessary liaison with the supported arm commander. From mid World War II some artillery observers were authorized to order fire to all batteries of their regiment, it also became

612-500: A core, with the first drilled bore ordnance recorded in operation near Seville in 1247. They fired lead, iron, or stone balls, sometimes large arrows and on occasions simply handfuls of whatever scrap came to hand. During the Hundred Years' War , these weapons became more common, initially as the bombard and later the cannon . Cannons were always muzzle-loaders . While there were many early attempts at breech-loading designs,

714-459: A direct fire weapon, hence the bullet-shields fitted to the carriages of guns such as the famous M1897 75 mm). It is also used with missiles , howitzers , rocket artillery , multiple rocket launchers , cruise missiles , ballistic missiles , naval guns against shore targets, sometimes with machine guns , and has been used with tank and anti-tank guns and by anti-aircraft guns against surface targets. There are two dimensions in aiming

816-408: A field carriage, immobility once emplaced, highly individual design, and noted unreliability (in 1460 James II , King of Scots, was killed when one exploded at the siege of Roxburgh). Their large size precluded the barrels being cast and they were constructed out of metal staves or rods bound together with hoops like a barrel, giving their name to the gun barrel . The use of the word "cannon" marks

918-438: A headquarters from various sources of information (spotters): observers on the ground, in aircraft, or in observation balloons . The development of electrical communication immensely simplified reporting, and enabled many widely dispersed firers to concentrate their fire on one target. The trajectory of the projectile could not be altered once fired, until the introduction of smart munitions . Indirect arrow fire by archers

1020-521: A hollow iron ball filled with pitch and fuse, designed to be fired at close range and burst on contact. The most popular in Portuguese arsenals was the berço , a 5 cm, one pounder bronze breech-loading cannon that weighted 150 kg with an effective range of 600 meters. A tactical innovation the Portuguese introduced in fort defense was the use of combinations of projectiles against massed assaults. Although canister shot had been developed in

1122-448: A known azimuth , or at least towards a target area. Initially, the angle between the aiming point and target area is deduced, or estimated, and set on the azimuth sight . Each gun is then laid on the aiming point, with this angle in order to keep them aimed roughly parallel to each other. However, for artillery another instrument, called either a director (United Kingdom) or aiming circle (United States), became widespread and eventually

1224-478: A lack of engineering knowledge rendered these even more dangerous to use than muzzle-loaders. In 1415, the Portuguese invaded the Mediterranean port town of Ceuta . While it is difficult to confirm the use of firearms in the siege of the city, it is known the Portuguese defended it thereafter with firearms, namely bombardas , colebratas , and falconetes . In 1419, Sultan Abu Sa'id led an army to reconquer

1326-475: A mid-19th-century 12-pounder gun , which fired a 4.1 kg (9.0 lb) round, with a kinetic energy of 240 kilojoules, or a 20th-century US battleship that fired a 1,225 kg (2,701 lb) projectile from its main battery with an energy level surpassing 350 megajoules . From the Middle Ages through most of the modern era , artillery pieces on land were moved by horse-drawn gun carriages . In

1428-497: A prelude to a decisive infantry and cavalry assault. Physically, cannons continued to become smaller and lighter. During the Seven Years War, King Frederick II of Prussia used these advances to deploy horse artillery that could move throughout the battlefield. Frederick also introduced the reversible iron ramrod, which was much more resistant to breakage than older wooden designs. The reversibility aspect also helped increase

1530-565: A sixth of all rounds used by the Portuguese in Morocco were of the fused-shell variety. The new Ming Dynasty established the "Divine Engine Battalion" (神机营), which specialized in various types of artillery. Light cannons and cannons with multiple volleys were developed. In a campaign to suppress a local minority rebellion near today's Burmese border, "the Ming army used a 3-line method of arquebuses/muskets to destroy an elephant formation". When

1632-565: A strong integrating effect on emerging nation-states, as kings were able to use their newfound artillery superiority to force any local dukes or lords to submit to their will, setting the stage for the absolutist kingdoms to come. Modern rocket artillery can trace its heritage back to the Mysorean rockets of Mysore . Their first recorded use was in 1780 during the battles of the Second , Third and Fourth Mysore Wars . The wars fought between

1734-422: A surface parallel to the axis of the bore or physically integrated into some form of sight mount. Some guns had clinometers graduated in distances instead of angles. Clinometers had several other names including "gunner's level", "range scale", "elevation drum" and "gunner’s quadrant" and several different configurations. Those graduated in ranges were specific to a type of gun. These arrangements lasted for most of

1836-566: A tank – initially a Stuart but in NW Europe usually a Sherman . Tanks continued to be used by some observers until about 1975. In 2002 the British Army adopted the term Fire Support Team (FST) for its observation parties, including FACs under control of the artillery officer commanding the FST. A functionally similar title is a mortar fire controller (MFC). An MFC is an infantry NCO who

1938-437: A target which cannot be seen by the aimer." The implication is that azimuth and/or elevation 'aiming' is done using instrumental methods. Hence indirect fire means applying 'firing data' to azimuth and elevation sights and laying these sights. Longer range uses a higher trajectory, and in theory maximum range is achieved with an elevation angle of 45 degrees. It is reasonable to assume that original purpose of indirect fire

2040-515: A weapon: The projectile trajectory is affected by atmospheric conditions, the velocity of the projectile, the difference in altitude between the firer and the target, and other factors. Direct fire sights may include mechanisms to compensate for some of these. Handguns and rifles , machine guns, anti-tank guns, tank main guns, many types of unguided rockets , and guns mounted in aircraft are examples of weapons primarily designed for direct fire. NATO defines indirect fire as "Fire delivered at

2142-610: Is a forward air controller , while for the equivalent for naval gunfire support is a spotter. For general fire support, the position is known as a fire support specialist (FiSTer) or simply an observer. In the U.S. Army, a Light, Heavy, or Stryker Infantry company Fire Support Team (FIST) consists of a Fire Support Officer (FSO), a Fire Support Sergeant, three Forward Observers (FO), two Fire Support Specialists and three Radio Telephone Operators (RTO). Armored/Cavalry FIST teams usually consist of just one FSO and three enlisted personnel. Brigade COLT teams operate in groups of two individuals,

2244-421: Is a widely used generic term for a projectile, which is a component of munitions . By association, artillery may also refer to the arm of service that customarily operates such engines. In some armies, the artillery arm has operated field , coastal , anti-aircraft , and anti-tank artillery; in others these have been separate arms, and with some nations coastal has been a naval or marine responsibility. In

2346-441: Is aiming and firing a projectile without relying on a direct line of sight between the gun and its target, as in the case of direct fire . Aiming is performed by calculating azimuth and inclination , and may include correcting aim by observing the fall of shot and calculating new angles. Indirect fire is most commonly used by field artillery and mortars (although field artillery was originally and until after World War I

2448-437: Is an indirect fire weapon system, the guns are rarely in line-of-sight of their target, often located miles away. The observer serves as the eyes of the guns, by sending target locations and if necessary corrections to the fall of shot, usually by radio . Equipment used in the observer role ranges from binoculars to laser rangefinders to unmanned aerial vehicles . When attached to a special forces unit, an artillery observer

2550-491: Is often tasked with coordinating fire from long-range artillery guns against high-value targets such as enemy headquarters. This is in contrast to an artillery observer's typical work with field/line artillery, which works in support of its own combat group. Such patrols may also form into 'stay behind' parties which deliberately hide in special observation hides as the main force fights a withdrawal. Broadly, there are two very different approaches to artillery observation. Either

2652-498: Is part of their battalion's mortar platoon. He controls platoon's fire in the same way as an FOO. The introduction of FSTs places MFCs under tactical control of the FST commander. Training, enabled by simulators, allows most soldiers to observe artillery fire, which has long been possible via a FOO. The Royal Flying Corps and Royal Air Force had been responsible reporting targets and observation of fire in World War I, this role

2754-432: Is used to correct the fall of shot onto the target; this may be required for several possible reasons: Predicted fire , originally called "map shooting", was introduced in World War I. It means that firing data is calculated to include corrections for the current prevailing conditions. It requires the target location to be precisely known relative to the gun location. Adjusted and predicted fire are not mutually exclusive,

2856-523: The Battle of Waterloo where a battery of the Royal Horse Artillery fired an indirect Shrapnel barrage against advancing French troops using corrections given by the commander of an adjacent battery with a direct line of sight. Modern indirect fire dates from the late 19th century. In 1882 a Russian, Lt Col K. G. Guk, published Field Artillery Fire from Covered Positions that described

2958-676: The British East India Company and the Kingdom of Mysore in India made use of the rockets as a weapon. In the Battle of Pollilur , the Siege of Seringapatam (1792) and in Battle of Seringapatam in 1799, these rockets were used with considerable effect against the British. After the wars, several Mysore rockets were sent to England, but experiments with heavier payloads were unsuccessful. In 1804 William Congreve, considering

3060-629: The Napoleonic Wars , the industrialist William Armstrong was awarded a contract by the government to design a new piece of artillery. Production started in 1855 at the Elswick Ordnance Company and the Royal Arsenal at Woolwich , and the outcome was the revolutionary Armstrong Gun , which marked the birth of modern artillery. Three of its features particularly stand out. Indirect fire Indirect fire

3162-407: The catapult , onager , trebuchet , and ballista , are also referred to by military historians as artillery. During medieval times, more types of artillery were developed, most notably the counterweight trebuchet. Traction trebuchets, using manpower to launch projectiles, have been used in ancient China since the 4th century as anti-personnel weapons. The much more powerful counterweight trebuchet

3264-536: The contemporary era , artillery pieces and their crew relied on wheeled or tracked vehicles as transportation. These land versions of artillery were dwarfed by railway guns ; the largest of these large-calibre guns ever conceived – Project Babylon of the Supergun affair – was theoretically capable of putting a satellite into orbit . Artillery used by naval forces has also changed significantly, with missiles generally replacing guns in surface warfare . Over

3366-563: The gunner's quadrant (see clinometer ) in the 16th century introduced indirect fire guns because it enabled gunlaying by instrument instead of line of sight. This instrument was basically a carpenter's set square with a graduated arc and plumb-bob placed in the muzzle to measure an elevation. There are suggestions, based on an account in Livre de Canonerie published in 1561 and reproduced in Revue d'Artillerie of March 1908, that indirect fire

3468-616: The siege of Constantinople in 1453 weighed 19 tons , took 200 men and sixty oxen to emplace, and could fire just seven times a day. The Fall of Constantinople was perhaps "the first event of supreme importance whose result was determined by the use of artillery" when the huge bronze cannons of Mehmed II breached the city's walls, ending the Byzantine Empire , according to Sir Charles Oman . Bombards developed in Europe were massive smoothbore weapons distinguished by their lack of

3570-442: The 15th century. The development of specialized pieces—shipboard artillery, howitzers and mortars —was also begun in this period. More esoteric designs, like the multi-barrel ribauldequin (known as "organ guns"), were also produced. The 1650 book by Kazimierz Siemienowicz Artis Magnae Artilleriae pars prima was one of the most important contemporary publications on the subject of artillery. For over two centuries this work

3672-551: The 16th century unequalled by contemporary European neighbours, in part due to the experience gained in intense fighting in Morocco, which served as a proving ground for artillery and its practical application, and made Portugal a forerunner in gunnery for decades. During the reign of King Manuel (1495–1521) at least 2017 cannon were sent to Morocco for garrison defense, with more than 3000 cannon estimated to have been required during that 26-year period. An especially noticeable division between siege guns and anti-personnel guns enhanced

3774-440: The 16th century, cannon were largely (though not entirely) displaced from the battlefield—the cannon were too slow and cumbersome to be used and too easily lost to a rapid enemy advance. The combining of shot and powder into a single unit, a cartridge, occurred in the 1620s with a simple fabric bag, and was quickly adopted by all nations. It speeded loading and made it safer, but unexpelled bag fragments were an additional fouling in

3876-405: The 20th century until robust, reliable and cost-effectively accurate gyroscopes provided a means of pointing gun or launcher in any required azimuth and elevation, thereby enabling indirect fire without using external aiming points. These devices use gyros in all three axes to determine current elevation, azimuth and trunnion tilt. Before a gun or launcher can be aimed, it must be oriented towards

3978-431: The 20th century, target acquisition devices (such as radar) and techniques (such as sound ranging and flash spotting ) emerged, primarily for artillery. These are usually utilized by one or more of the artillery arms. The widespread adoption of indirect fire in the early 20th century introduced the need for specialist data for field artillery, notably survey and meteorological, and in some armies, provision of these are

4080-541: The Detachment Commander, and the highest number being the Coverer, the second-in-command. "Gunner" is also the lowest rank, and junior non-commissioned officers are "Bombardiers" in some artillery arms. Batteries are roughly equivalent to a company in the infantry, and are combined into larger military organizations for administrative and operational purposes, either battalions or regiments, depending on

4182-576: The English-held towns of Jargeau, Meung, and Beaugency, all with the support of large artillery units. When she led the assault on Paris, Joan faced stiff artillery fire, especially from the suburb of St. Denis, which ultimately led to her defeat in this battle. In April 1430, she went to battle against the Burgundians, whose support was purchased by the English. At this time, the Burgundians had

4284-636: The Fire Support Coordinator (FSC), Battalion Fire Support Officer (FSO), and Battalion Air Officer (Air-O). For centuries the Battery Commander had been responsible for controlling the fire of their battery. This continued with the introduction of indirect fire in the early years of the 20th Century. However, the First World War introduced 24 hour, seven days a week fighting. Furthermore, indirect fire had increased

4386-430: The First World War an important task for aircraft — both heavier-than-air or balloons — was artillery spotting . In naval use several ships may be shooting at the same target, making identifying the fall of shot from a particular ship difficult; different-coloured dyes for each ship were often used to help with spotting. Fire may be "adjusted" or "predicted". Adjusting (originally "ranging") means some form of observation

4488-684: The Javanese were considered excellent in casting artillery, and in the knowledge of using it. In 1513, the Javanese fleet led by Pati Unus sailed to attack Portuguese Malacca "with much artillery made in Java, for the Javanese are skilled in founding and casting, and in all works in iron , over and above what they have in India ". By the early 16th century, the Javanese had already started locally-producing large guns, which were dubbed "sacred cannon[s]" or "holy cannon[s]" and have survived up to

4590-653: The Mysorian rockets to have too short a range (less than 1,000 yards) developed rockets in numerous sizes with ranges up to 3,000 yards and eventually utilizing iron casing as the Congreve rocket which were used effectively during the Napoleonic Wars and the War of 1812 . With the Napoleonic Wars, artillery experienced changes in both physical design and operation. Rather than being overseen by "mechanics", artillery

4692-525: The Portuguese and Spanish arrived at Southeast Asia, they found that the local kingdoms were already using cannons. Portuguese and Spanish invaders were unpleasantly surprised and even outgunned on occasion. Duarte Barbosa ca. 1514 said that the inhabitants of Java were great masters in casting artillery and very good artillerymen. They made many one-pounder cannons (cetbang or rentaka ), long muskets, spingarde (arquebus), schioppi (hand cannon), Greek fire , guns (cannons), and other fire-works. In all aspects

4794-473: The Soviet Union tended towards the British method. In the British system, the observer sends a fire order to their own and any other batteries authorized to them, and may request fire from additional batteries. Each battery command post converts the fire orders into firing data for its own guns. Until post-World War II the observer would usually order actual firing data to the guns of their own troop, this

4896-530: The army. These may be grouped into brigades; the Russian army also groups some brigades into artillery divisions, and the People's Liberation Army has artillery corps. The term "artillery" also designates a combat arm of most military services when used organizationally to describe units and formations of the national armed forces that operate the weapons. During military operations , field artillery has

4998-619: The bronze "thousand ball thunder cannon", an early example of field artillery . These small, crude weapons diffused into the Middle East (the madfaa ) and reached Europe in the 13th century, in a very limited manner. In Asia, Mongols adopted the Chinese artillery and used it effectively in the great conquest . By the late 14th century, Chinese rebels used organized artillery and cavalry to push Mongols out. As small smooth-bore barrels, these were initially cast in iron or bronze around

5100-431: The course of military history, projectiles were manufactured from a wide variety of materials, into a wide variety of shapes, using many different methods in which to target structural/defensive works and inflict enemy casualties . The engineering applications for ordnance delivery have likewise changed significantly over time, encompassing some of the most complex and advanced technologies in use today. In some armies,

5202-461: The current context originated in the Middle Ages . One suggestion is that it comes from French atelier , meaning the place where manual work is done. Another suggestion is that it originates from the 13th century and the Old French artillier , designating craftsmen and manufacturers of all materials and warfare equipments (spears, swords, armor, war machines); and, for the next 250 years,

SECTION 50

5304-617: The defense in a siege was lost. Cannons during this period were elongated, and the recipe for gunpowder was improved to make it three times as powerful as before. These changes led to the increased power in the artillery weapons of the time. Joan of Arc encountered gunpowder weaponry several times. When she led the French against the English at the Battle of Tourelles, in 1430, she faced heavy gunpowder fortifications, and yet her troops prevailed in that battle. In addition, she led assaults against

5406-415: The development of artillery ordnance, systems, organizations, and operations until the present, with artillery systems capable of providing support at ranges from as little as 100 m to the intercontinental ranges of ballistic missiles . The only combat in which artillery is unable to take part is close-quarters combat , with the possible exception of artillery reconnaissance teams. The word as used in

5508-500: The distance between the guns and their targets, and between the observers and their guns. This led to the use of observing officers to act on behalf of the battery commander. In the 1938 re-organization of the Royal Artillery batteries were divided into troops, with the troop commanders (Captains) as observing officers at an (OP). These officers and their parties could operate as either as an Observation Post (OP) or accompany

5610-453: The early 15th century, the Portuguese were the first to employ it extensively, and Portuguese engineers invented a canister round which consisted of a thin lead case filled with iron pellets, that broke up at the muzzle and scattered its contents in a narrow pattern. An innovation which Portugal adopted in advance of other European powers was fuse-delayed action shells, and were commonly used in 1505. Although dangerous, their effectiveness meant

5712-414: The end of the 14th century, cannons were only powerful enough to knock in roofs, and could not penetrate castle walls. However, a major change occurred between 1420 and 1430, when artillery became much more powerful and could now batter strongholds and fortresses quite efficiently. The English, French, and Burgundians all advanced in military technology, and as a result the traditional advantage that went to

5814-433: The enemy by obscuring their view. Fire may be directed by an artillery observer or another observer, including crewed and uncrewed aircraft, or called onto map coordinates . Military doctrine has had a significant influence on the core engineering design considerations of artillery ordnance through its history, in seeking to achieve a balance between the delivered volume of fire with ordnance mobility. However, during

5916-410: The fallen city, and Marinids brought cannons and used them in the assault on Ceuta. Finally, hand-held firearms and riflemen appear in Morocco, in 1437, in an expedition against the people of Tangiers . It is clear these weapons had developed into several different forms, from small guns to large artillery pieces. The artillery revolution in Europe caught on during the Hundred Years' War and changed

6018-406: The former may use predicted data and the latter may need adjusting in some circumstances. There are two approaches to the azimuth that orients the guns of a battery for indirect fire. Originally "zero", meaning 6400 mils, 360 degrees or their equivalent, was set at whatever the direction the oriented gun was pointed. Firing data was a deflection or switch from this zero. The other method was to set

6120-494: The ground breaking legs and ankles. The development of modern artillery occurred in the mid to late 19th century as a result of the convergence of various improvements in the underlying technology. Advances in metallurgy allowed for the construction of breech-loading rifled guns that could fire at a much greater muzzle velocity . After the British artillery was shown up in the Crimean War as having barely changed since

6222-423: The gun barrel and a new tool—a worm —was introduced to remove them. Gustavus Adolphus is identified as the general who made cannon an effective force on the battlefield—pushing the development of much lighter and smaller weapons and deploying them in far greater numbers than previously. The outcome of battles was still determined by the clash of infantry. Shells, explosive-filled fused projectiles, were in use by

SECTION 60

#1732797330976

6324-418: The introduction in the 15th century of a dedicated field carriage with axle, trail and animal-drawn limber—this produced mobile field pieces that could move and support an army in action, rather than being found only in the siege and static defenses. The reduction in the size of the barrel was due to improvements in both iron technology and gunpowder manufacture, while the development of trunnions —projections at

6426-470: The introduction of a gun shield necessary. The problems of how to employ a fixed or horse-towed gun in mobile warfare necessitated the development of new methods of transporting the artillery into combat. Two distinct forms of artillery were developed: the towed gun, used primarily to attack or defend a fixed-line; and the self-propelled gun, intended to accompany a mobile force and to provide continuous fire support and/or suppression. These influences have guided

6528-486: The largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to shell -firing guns , howitzers , and mortars (collectively called barrel artillery , cannon artillery or gun artillery ) and rocket artillery . In common speech,

6630-451: The modern period, the consideration of protecting the gunners also arose due to the late-19th-century introduction of the new generation of infantry weapons using conoidal bullet , better known as the Minié ball , with a range almost as long as that of field artillery. The gunners' increasing proximity to and participation in direct combat against other combat arms and attacks by aircraft made

6732-468: The nuts, bolts and screws made their mass production and repair much easier. While the Gribeauval system made for more efficient production and assembly, the carriages used were heavy and the gunners were forced to march on foot (instead of riding on the limber and gun as in the British system). Each cannon was named for the weight of its projectiles, giving us variants such as 4, 8, and 12, indicating

6834-484: The observer has command authority and orders fire, including the type and amount of ammunition to be fired, to batteries. Or the observer requests fire from an artillery headquarters at some level, which decides if fire will be provided, by which batteries, and the type and amount of ammunition to be provided. The first is characterized by the British, the second by the United States. In World War II both Germany and

6936-577: The practice for some observers to be designated 'Commander's Representative' able to order fire to a divisional or corps artillery. Unauthorized officers could request fire from more than their own battery. During that war it also became the practice that FOOs arranged quick fireplans comprising several coordinated targets engaged by guns and mortars to support short offensive actions by the squadron or company they were with. In World War II OP/FOO parties were normally mounted in an armored carrier , although those assigned to support armored brigades usually had

7038-701: The present day - though in limited numbers. These cannons varied between 180 and 260 pounders, weighing anywhere between 3–8 tons, measuring between 3–6 m. Between 1593 and 1597, about 200,000 Korean and Chinese troops which fought against Japan in Korea actively used heavy artillery in both siege and field combat. Korean forces mounted artillery in ships as naval guns , providing an advantage against Japanese navy which used Kunikuzushi (国崩し – Japanese breech-loading swivel gun ) and Ōzutsu (大筒 – large size Tanegashima ) as their largest firearms. Bombards were of value mainly in sieges . A famous Turkish example used at

7140-511: The primary method of orienting guns in most if not all armies. After being oriented and pointed in the required direction a gun recorded angles to one or more aiming points. Such early directors were the progenitors of the later general class of directors . Indirect fire needs a command and control arrangement to allot guns to targets and direct their fire. The latter may involve ground or air observers or technical devices and systems. Observers report where shots fall so that aim may be corrected. In

7242-418: The range of artillery increased, allowing each battery to have an ever-greater area of influence, but required command and control arrangements to enable concentration of fire. The physical laws of ballistics means that guns firing larger and heavier projectile can send them farther than smaller-calibre guns firing lighter shells. By the end of the 20th century, the typical maximum range for the most common guns

7344-468: The rate of fire, since a soldier would no longer have to worry about what end of the ramrod they were using. Jean-Baptiste de Gribeauval , a French artillery engineer, introduced the standardization of cannon design in the mid-18th century. He developed a 6-inch (150 mm) field howitzer whose gun barrel, carriage assembly and ammunition specifications were made uniform for all French cannons. The standardized interchangeable parts of these cannons down to

7446-406: The responsibility of the artillery arm. The majority of combat deaths in the Napoleonic Wars , World War I , and World War II were caused by artillery. In 1944, Joseph Stalin said in a speech that artillery was "the god of war". Although not called by that name, siege engines performing the role recognizable as artillery have been employed in warfare since antiquity. The first known catapult

7548-548: The role of providing support to other arms in combat or of attacking targets, particularly in-depth. Broadly, these effects fall into two categories, aiming either to suppress or neutralize the enemy, or to cause casualties, damage, and destruction. This is mostly achieved by delivering high-explosive munitions to suppress, or inflict casualties on the enemy from casing fragments and other debris and from blast , or by destroying enemy positions, equipment, and vehicles. Non-lethal munitions, notably smoke, can also suppress or neutralize

7650-620: The rotatable top of the sight above the height of the layer's head. The German Goertz 1906 design was selected by both the British and the Russians. The British adopted the name "Dial Sight" for this instrument; the US used "Panoramic Telescope"; the Russia used " Goertz panorama ". Elevations were measured by a clinometer , a device using a spirit level to measure a vertical angle from the horizontal plane. These could be separate instruments placed on

7752-735: The sense of the word "artillery" covered all forms of military weapons. Hence, the naming of the Honourable Artillery Company , which was essentially an infantry unit until the 19th century. Another suggestion is that it comes from the Italian arte de tirare (art of shooting), coined by one of the first theorists on the use of artillery, Niccolò Tartaglia . The term was used by Girolamo Ruscelli (died 1566) in his Precepts of Modern Militia published posthumously in 1572. Mechanical systems used for throwing ammunition in ancient warfare, also known as " engines of war ", like

7854-466: The side of the cannon as an integral part of the cast—allowed the barrel to be fixed to a more movable base, and also made raising or lowering the barrel much easier. The first land-based mobile weapon is usually credited to Jan Žižka , who deployed his oxen-hauled cannon during the Hussite Wars of Bohemia (1418–1424). However, cannons were still large and cumbersome. With the rise of musketry in

7956-476: The siege of Roxburgh Castle in 1460. The able use of artillery supported to a large measure the expansion and defense of the Portuguese Empire , as it was a necessary tool that allowed the Portuguese to face overwhelming odds both on land and sea from Morocco to Asia. In great sieges and in sea battles, the Portuguese demonstrated a level of proficiency in the use of artillery after the beginning of

8058-454: The siege sixty-nine guns in fifteen separate batteries and trained them at the walls of the city. The barrage of Ottoman cannon fire lasted forty days, and they are estimated to have fired 19,320 times. Artillery also played a decisive role in the Battle of St. Jakob an der Birs of 1444. Early cannon were not always reliable; King James II of Scotland was killed by the accidental explosion of one of his own cannon, imported from Flanders, at

8160-453: The sighting arrangements used by the Boers with their German and French guns is unclear. The early goniometric devices suffered from the problem that the layer (gun aimer) had to move around to look through the sight. This was very unsatisfactory if the aiming point was not to the front, particularly on larger guns. The solution was a periscopic panoramic sight, with the eyepiece to the rear and

8262-670: The strongest and largest gunpowder arsenal among the European powers, and yet the French, under Joan of Arc's leadership, were able to beat back the Burgundians and defend themselves. As a result, most of the battles of the Hundred Years' War that Joan of Arc participated in were fought with gunpowder artillery. The army of Mehmet the Conqueror , which conquered Constantinople in 1453, included both artillery and foot soldiers armed with gunpowder weapons. The Ottomans brought to

8364-417: The supported arm (infantry or armour) as Forward Observation Officers (FOOs). During World War II it became the practice for close support battery commanders to become part of the tank regiment or infantry battalion headquarters they were supporting. They also started using 'quick fireplans' usually limited to their own regiment, to support fast moving limited battalion actions. Generally FOOs were assigned to

8466-509: The target depended on the terrain and battlefield situation. Elevated observation posts could be used as an aid to facilitate communication between the guns and the observers. The development of optical and communication aids for observation advanced significantly in the First and Second World Wars . In the 21st century, Joint Tactical Fire Support observers emerged usually using sophisticated communications engineering systems. Because artillery

8568-609: The target, behind enemy lines, and subject to attack. Artillery Artillery are ranged weapons that launch munitions far beyond the range and power of infantry firearms . Early artillery development focused on the ability to breach defensive walls and fortifications during sieges , and led to heavy, fairly immobile siege engines . As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing

8670-406: The term "gunners" for the soldiers and sailors with the primary function of using artillery. The gunners and their guns are usually grouped in teams called either "crews" or "detachments". Several such crews and teams with other functions are combined into a unit of artillery, usually called a battery , although sometimes called a company. In gun detachments, each role is numbered, starting with "1"

8772-634: The use and effectiveness of Portuguese firearms above contemporary powers, making cannon the most essential element in the Portuguese arsenal. The three major classes of Portuguese artillery were anti-personnel guns with a high borelength (including: rebrodequim , berço , falconete , falcão , sacre , áspide , cão , serpentina and passavolante ); bastion guns which could batter fortifications ( camelete , leão , pelicano , basilisco , águia , camelo , roqueira , urso ); and howitzers that fired large stone cannonballs in an elevated arch, weighted up to 4000 pounds and could fire incendiary devices, such as

8874-492: The way that battles were fought. In the preceding decades, the English had even used a gunpowder-like weapon in military campaigns against the Scottish. However, at this time, the cannons used in battle were very small and not particularly powerful. Cannons were only useful for the defense of a castle , as demonstrated at Breteuil in 1356, when the besieged English used a cannon to destroy an attacking French assault tower. By

8976-580: The weapon of artillery is the projectile, not the equipment that fires it. The process of delivering fire onto the target is called gunnery. The actions involved in operating an artillery piece are collectively called "serving the gun" by the "detachment" or gun crew, constituting either direct or indirect artillery fire. The manner in which gunnery crews (or formations) are employed is called artillery support. At different periods in history, this may refer to weapons designed to be fired from ground-, sea-, and even air-based weapons platforms . Some armed forces use

9078-421: The weight in pounds. The projectiles themselves included solid balls or canister containing lead bullets or other material. These canister shots acted as massive shotguns, peppering the target with hundreds of projectiles at close range. The solid balls, known as round shot , was most effective when fired at shoulder-height across a flat, open area. The ball would tear through the ranks of the enemy or bounce along

9180-573: The word "artillery" is often used to refer to individual devices, along with their accessories and fittings, although these assemblages are more properly called "equipment". However, there is no generally recognized generic term for a gun, howitzer, mortar, and so forth: the United States uses "artillery piece", but most English-speaking armies use "gun" and "mortar". The projectiles fired are typically either " shot " (if solid) or "shell" (if not solid). Historically, variants of solid shot including canister , chain shot and grapeshot were also used. "Shell"

9282-496: Was a gun-mounted rotatable open sight, mounted in alignment with the bore, and able to measure large angles from it. Similar designs, usually able to measure angles in a full circle, were widely adopted over the following decade. By the early 1900s the open sight was sometimes replaced by a telescope and the term goniometer had replaced "lining-plane" in English. The first incontrovertible, documented use of indirect fire in war using Guk's methods, albeit without lining-plane sights,

9384-444: Was about 24 to 30 km, up from about 8 km in World War I. During World War I, covered positions moved farther back and indirect fire evolved to allow any point within range to be attacked, firepower mobility , without moving the firers. If the target cannot be seen from the gun position, there has to be a means of identifying targets and correcting aim according to fall of shot. The position of some targets may be identified by

9486-495: Was commonly used by ancient armies. It was used during both battles and sieges. For several centuries Coehorn mortars were fired indirectly because their fixed elevation meant range was determined by the amount of propelling powder. It is also reasonable conjecture that if these mortars were used from inside fortifications their targets may have been invisible to them and therefore met the definition of indirect fire. It could also be argued that Niccolò Tartaglia 's invention of

9588-496: Was developed in Syracuse in 399 BC. Until the introduction of gunpowder into western warfare, artillery was dependent upon mechanical energy which not only severely limited the kinetic energy of the projectiles, it also required the construction of very large engines to accumulate sufficient energy. A 1st-century BC Roman catapult launching 6.55 kg (14.4 lb) stones achieved a kinetic energy of 16 kilojoules , compared to

9690-458: Was enabled by the use of calibrating sights on the guns. In the U.S. system, the observer sends a request for fire, usually to their battalion or battery Fire Direction Center (FDC). The FDC then decides how much fire to permit and may request additional fire from a higher artillery headquarters. FDC(s) convert the observer's target information into firing data for the battery's weapons. The equivalent of an artillery observer for close air support

9792-454: Was invented in the eastern Mediterranean region in the 12th century, with the earliest definite attestation in 1187. Early Chinese artillery had vase-like shapes. This includes the "long range awe inspiring" cannon dated from 1350 and found in the 14th century Ming dynasty treatise Huolongjing . With the development of better metallurgy techniques, later cannons abandoned the vase shape of early Chinese artillery. This change can be seen in

9894-473: Was on 26 October 1899 by British gunners during the Second Boer War . Although both sides demonstrated early on in the conflict that they could use the technique effectively, in many subsequent battles, British commanders nonetheless ordered artillery to be "less timid" and to move forward to address troops' concerns about their guns abandoning them. The British used improvised gun arcs with howitzers;

9996-699: Was subsequently called 'Arty/R, but proved difficult from high performance aircraft over hostile territory in World War II. In 1940 it was agreed that RAF AOP squadrons equipped with light aircraft, operating at low altitude over friendly territory and flown by Royal Artillery officers would be formed. These squadrons existed until the formation of the Army Air Corps in 1957. Since the development of small unmanned aerial vehicles, they have been used for identifying targets, spotting fall of shot , and correcting aim. Operators are usually relatively close to

10098-455: Was to enable fire from a 'covered position', one where gunners can not be seen and engaged by their enemies (that and as the range of artillery lengthened, it was impossible to see the target past all the intervening terrain). The concealment aspect remains important, but from World War I equally important was the capability to concentrate the fire of many artillery batteries at the same target or set of targets. This became increasingly important as

10200-480: Was used by the Burgundians in the 16th century. The Russians seem to have used something similar at Paltzig in 1759 where they fired over trees, and their instructions of the time indicate this was a normal practice. These methods probably involved an aiming point positioned in line with the target. The earliest example of indirect fire adjusted by an observer seems to be during the defence of Hougoumont in

10302-501: Was used in Europe as a basic artillery manual. One of the most significant effects of artillery during this period was however somewhat more indirect—by easily reducing to rubble any medieval-type fortification or city wall (some which had stood since Roman times), it abolished millennia of siege-warfare strategies and styles of fortification building. This led, among other things, to a frenzy of new bastion -style fortifications to be built all over Europe and in its colonies, but also had

10404-423: Was viewed as its own service branch with the capability of dominating the battlefield. The success of the French artillery companies was at least in part due to the presence of specially trained artillery officers leading and coordinating during the chaos of battle. Napoleon , himself a former artillery officer, perfected the tactic of massed artillery batteries unleashed upon a critical point in his enemies' line as
