With the advent of longer range and more accurate weapons, especially the repeating rifle, camouflage was adopted for the uniforms of all armies, spreading to most forms of military equipment including ships and aircraft. Camouflage for equipment and positions was extensively developed for military use by the French in 1915, soon followed by other World War I armies. In both world wars, artists were recruited as camouflage officers. Ship camouflage developed via conspicuous

Compromises

While camouflage tricks are in principle limitless, both cost and practical considerations limit the choice of methods and the time and effort devoted to camouflage. Paint and uniforms must also protect vehicles and soldiers from the elements. Units need to move, fire their weapons and perform other tasks to keep functional, some of which run counter to camouflage. Camouflage may be dropped altogether. Late in the Second World War, the

and weight, or to reduce vulnerability to radiation from nuclear weapons. No single camouflage pattern is effective in all terrains. The effectiveness of a pattern depends on contrast as well as colour tones. Strong contrasts which disrupt outlines are better suited for environments such as forests where the play of light and shade is prominent, while low contrasts are better suited to open terrain with little shading structure. Terrain-specific camouflage patterns, made to match the local terrain, may be more effective in that terrain than more general patterns. However, unlike an animal or a civilian hunter, military units may need to cross several terrain types like woodland, farmland and built up areas in a single day. While civilian hunting clothing may have almost photo-realistic depictions of tree bark or leaves (indeed, some such patterns are based on photographs), military camouflage is designed to work in a range of environments. With the cost of uniforms in particular being substantial, most armies operating globally have two separate full uniforms, one for woodland/jungle and one for desert and other dry terrain. An American attempt at a global camouflage pattern for all environments (the 2004 UCP) was produced, however after a few years of service it was withdrawn due to poor performance. On the other end of the scale are terrain specific patterns like the "Berlin camo", applied to British vehicles operating in

Snow camouflage

Seasons may play a role in some regions. A dramatic change in colour and texture is created by seasonal snowy conditions in northern latitudes, necessitating repainting of vehicles and separate snow oversuits. The Eastern and northern European countries have a tradition for separate winter uniforms rather than oversuits. During the Second World War, the

Digital camouflage

Digital camouflage provides a disruptive effect through the use of pixellated patterns at a range of scales, meaning that the camouflage helps to defeat observation at a range of distances. Such patterns were first developed during the Second World War, when Johann Georg Otto Schick designed a number of patterns for the

(1756–1763), the rifle-armed Rogers' Rangers wore gray or green uniforms. John Graves Simcoe, one of the unit's later commanders, noted in 1784: The tradition was continued by British Rifle Brigade (Prince Consort's Own), Rifle Regiments who adopted rifle green for the Napoleonic Wars. During the Peninsular War, Military of Portugal, Portugal fielded light infantry units known as ''Caçadores'', who wore brown-jackets which helped conceal them. The brown color was considered to be more adequate for a concealment in the landscape of most of Portuguese regions, in general more arid than the greener landscapes of Central and Northern Europe. Other nations soon followed suit, dressing their rifle regiments and sometimes also light troops in suitable drab tones, usually variations of green or gray. The first introduction of drab general uniform was by the British Corps of Guides (British India), Corps of Guides in British India, India in 1848. Initially the drab uniform was specially imported from England, with one of the reasons being to "make them invisible in a land of dust". However, when a larger quantity was required the army improvised, using a local dye to produce uniform locally. This type of drab uniform soon became known as khaki (colour), khaki (Urdu for dusty, soil-coloured) by the Indian soldiers, and was of a similar colour to a local dress of cotton coloured with the Nannorrhops, mazari palm. The example was followed by other British units during the Indian Rebellion of 1857, mutiny of 1857, dying their white drill uniforms to inconspicuous tones with mud, tea, coffee or coloured inks. The resulting hue varied from dark or slate grey through light brown to off-white, or sometimes even lavender (colour), lavender. This improvised measure gradually became widespread among the troops stationed in India and North-West Frontier (military history), North-West Frontier, and sometimes among the troops campaigning on the African continent.


Rifle fire

While long range rifles became the standard weapon in the 1830s, armies were slow to adapt their tactics and uniforms, perhaps as a result of mainly fighting colonial wars against less well armed opponents. Not until the First Boer War of 1880/81 did a major European power meet an opponent well equipped with and well versed in the use of modern long range repeating firearms, forcing an immediate change in tactics and uniforms. Khaki-coloured uniform became standard service dress for both British Army, British and British Indian Army troops stationed in British India in 1885, and in 1896 khaki drill uniform was adopted by British Army for the service outside of Europe in general, but not until the Second Boer War, in 1902, did the entire British Army standardise on khaki (officially known as "drab") for Service Dress (British Army), Service Dress. The Military of the United States, US military, who had blue-jacketed rifle units in the American Civil War, Civil War, were quick to follow the British, going khaki in the same year. Russian Empire, Russia followed, partially, in 1908. The Italian Army used ''grigio-verde'' ("grey-green") in the Alps from 1906 and across the army from 1909. The German Empire, Germans adopted ''feldgrau'' ("field grey") in 1910. By the outbreak of the World War I, First World War in 1914, France was the only major power to still field soldiers dressed in traditional conspicuous uniforms.


The First World War

The World War I, First World War was the first full scale industrial conflict fought with modern firearms. The first attempt at disruptive camouflaged garment for the French army was proposed in 1914 by the painter Louis Guingot, but was refused by the army, which nevertheless kept a sample of the clothing. In collaboration with a Russian chemist friend, Guingot had developed a process of painting on weather-resistant fabric before the war and had registered a patent for it. But the casualty rate on the Western Front (World War I), Western Front forced the French to finally relinquish their blue coats and red trousers, adopting a grayish "horizon blue" uniform. The use of rapid firing machine guns and long range Rifled breech loader, breech loading artillery quickly led to camouflaging of vehicles and positions. Artillery pieces were soon painted in contrasting bold colours to obscure their outlines. Another early trend was building observation trees, made of steel with bark camouflage. Such trees became popular with the British and French armies in 1916. The observation tree was invented by French painter Lucien-Victor Guirand de Scévola, who led the French army's camouflage unit, the first of its kind in any army. He also invented painted canvas Net (textile), netting to hide machine gun positions, and this was quickly taken up for hiding equipment and gun positions from 1917, 7 million square yards being used by the end of the war. The First World War also saw the birth of aerial warfare, and with it the need not only to conceal positions and vehicles from being spotted from the air, but also the need to camouflage the aircraft themselves. In 1917, Germany started using a lozenge camouflage covering Central Powers aircraft, possibly the earliest printed camouflage. A similarly disruptive splinter pattern in earth tones, ''Buntfarbenanstrich 1918'', was introduced for tanks in 1918, and was also used on the Stahlhelm (steel helmet), becoming the first use of a standardized camouflage pattern for soldiers.


''Camoufleurs''

In 1909 an American artist and amateur zoologist, Abbott Thayer published a book, ''Concealing-Coloration in the Animal Kingdom'', which was widely read by military leaders, although his advocacy of
countershading Countershading, or Thayer's law, is a method of camouflage in which animal coloration, an animal's coloration is darker on the top or upper side and lighter on the underside of the body. This pattern is found in many species of mammals, reptile ...
was unsuccessful, despite his patent for countershading submarines and surface ships. The earliest camouflage artists were members of the Post-Impressionism, Post- Impressionist and Fauvism, Fauve schools of France. Contemporary artistic movements such as cubism, vorticism and impressionism also influenced the development of camouflage as they dealt with disrupting outlines, abstraction and colour theory.The French established a ''Section de Camouflage'' (Camouflage Department) at Amiens in 1915, headed by Lucien-Victor Guirand de Scévola. His ''camoufleurs'' included the artists Jacques Villon, André Dunoyer de Segonzac, Charles Camoin and André Mare. Camouflage schemes of the First World War and Interwar periods that employed dazzle patterns were often described as "cubist" by commentators, and Picasso claimed with typical hyperbole "Yes, it is we who made it, that is cubism". Most of the artists employed as ''camoufleurs'' were traditional representative painters, not cubists, but de Scévola claimed "In order to deform totally the aspect of the object, I had to employ the means that cubists use to represent it." Other countries soon saw the advantage of camouflage, and established their own units of artists, designers and architects. The British established a Camouflage Section in late 1916 at Wimereux, and the U.S. followed suit with the New York Camouflage Society in April 1917, the official American Camouflage Corps, Company A of 40th Engineers in January 1918 and the Women's Reserve Camouflage Corps. The Italians set up the ''Laboratorio di mascheramento'' in 1917. By 1918 de Scévola was in command of camouflage workshops with over 9,000 workers, not counting the ''camoufleurs'' working at the front itself. Norman Wilkinson (artist), Norman Wilkinson who first proposed dazzle camouflage to the British military employed 5 male designers and 11 women artists, who by the end of the war had painted more than 2,300 vessels. The technique utilized ''trompe l'oeil'' painting the sides of ships with geometric patterns of different shapes and sizes making it difficult to estimate ship size and direction of travel when seen at a distance. French women were employed behind the lines of both the British and American armies, sewing netting to disguise equipment and designing apparel for soldiers to wear.


From the Second World War

Printed camouflage for shelter half, shelter halves was introduced for the Italian and German armies in the interwar period, the "splotchy" Telo mimetico, M1929 Telo mimetico in Italy and the angular Splittermuster, Splittermuster 31 in Germany. During the War, both patterns were used for paratrooper uniforms for their respective countries. The British soon followed suit with a brush-stroke type pattern for their paratroopers' Denison smock, and the Soviets introduced an "amoeba" pattern overgarment for their snipers. Hugh Cott's 1940 book ''Adaptive Coloration in Animals'' systematically covered the different forms of camouflage and mimicry by which animals protect themselves, and explicitly drew comparisons throughout with military camouflage: Both British and Soviet aircraft were given wave-type camouflage paintwork for their upper surfaces throughout the war, while American ones remained simple two-colour schemes (different upper and under sides) or even dispensed with camouflage altogether. Italian and some Japanese aircraft wore sprayed-on spotted patterns. German aircraft mostly used an angular splint-pattern camouflage, but Germany experimented with different schemes, particularly in the later stages of the war. They also experimented with various spray-on camouflage patterns for tanks and other vehicles, while Allied vehicles remained largely uni-coloured. As they had volunteered in the first World War, women sewed camouflage netting, organizing formalized groups for the work in Australia, Britain, New Zealand and the United States who took part as camoufleurs during the second war. The British Middle East Command Camouflage Directorate, consisting mainly of artists recruited into the Royal Engineers, developed the use of camouflage for large-scale

. Operations combined the disguise of actual installations, vehicles and stores with the simultaneous display of dummies, whether to draw fire or to give a false idea of the strength of forces or likely attack directions. In Operation Bertram for the decisive battle at Second Battle of El Alamein, El Alamein, a whole dummy armoured division was constructed, while real tanks were disguised as soft-skinned transport using "Sunshield" covers. The capabilities so developed were put to use not only in the western desert, but also in Europe as in the Operation Bodyguard deception for the Invasion of Normandy, and in the Pacific campaign, as in the Battle of Goodenough Island#Aftermath, Battle of Goodenough Island. The introduction of strategic bombing led to efforts to camouflage airfields and strategic production centres. This form of positional camouflage could be quite elaborate, and even include false houses and cars. With the threat from nuclear weapons in the post-war era such elaborate camouflage was no longer seen as useful, as a direct hit would not be necessary with strategic nuclear weapons to destroy infrastructure. The Soviet Union's military doctrine, doctrine of Russian military deception, military deception defines the need for surprise through means including camouflage, based on experiences such as the Battle of Kursk where camouflage helped the Red Army to overwhelm a powerful enemy.


Application


Uniforms

The role of uniform is not only to hide each soldier, but also to identify friend from foe. Issue of the "Frog Skin, Frogskin" uniforms to US troops in Europe during the Second World War was halted as it was too often mistaken for the German World War II camouflage patterns, disruptively patterned German uniform worn by the Waffen-SS. Camouflage uniforms need to be made and distributed to a large number of soldiers. The design of camouflage uniforms therefore involves a tradeoff between camouflaging effect, recognizability, cost, and manufacturability. Armies facing service in different theatres may need several different camouflage uniforms. Separate issues of temperate/jungle and desert camouflage uniforms are common. Patterns can to some extent be adapted to different terrains by adding means of fastening pieces of vegetation to the uniform. Helmets often have netting covers; some jackets have small loops for the same purpose. Being able to find appropriate camouflage vegetation or in other ways modify the issued battle uniform to suit the local terrain is an important skill for infantry soldiers. Countries in boreal climates often need snow camouflage, either by having reversible uniforms or simple overgarments.


Land vehicles

The purpose of vehicle and equipment camouflage differs from personal camouflage in that the primary threat is aerial reconnaissance.The Handbook Of The SAS And Elite Forces. How The Professionals Fight And Win. Edited by Jon E. Lewis. p.329-Tactics And Techniques, Personal Skills And Techniques. Robinson Publishing Ltd 1997. ISBN 1-85487-675-9 The goal is to disrupt the characteristic shape of the vehicle, to reduce shine, and to make the vehicle difficult to identify even if it is spotted. Paint is the least effective measure, but forms a basis for other techniques. Military vehicles often become so dirty that pattern-painted camouflage is not visible, and although matte colours reduce shine, a wet vehicle can still be shiny, especially when viewed from above. Patterns are designed to make it more difficult to interpret shadows and shapes. The British Army adopted a disruptive scheme for vehicles operating in the stony desert of the North African Campaign and Greece, retrospectively known as the Caunter scheme. It used up to six colours applied with straight lines. The British Army's Special Air Service used pink as the primary colour on its desert-camouflaged Land Rover Series#Series IIA, Land Rover Series IIA patrol vehicles, nicknamed ''Pink Panthers''; the colour had been observed to be indistinguishable from sand at a distance. Nets can be effective at defeating visual observation. Traditional camouflage nets use a textile 'garnish' to generate an apparent texture with a depth of shadow created beneath it, and the effect can be reinforced with pieces of vegetation. Modern nets tend to be made of a continuous woven material, which is easier to deploy over a vehicle and lack the "windows" between patches of garnish of traditional nets. Some nets can remain in place while vehicles move. Simple nets are less effective in defeating radar and thermal sensors. Heavier, more durable "mobile camouflage systems", essentially conformal duvets with thermal and radar properties, provide a degree of concealment without the delay caused by having to spread nets around a vehicle.

background, has been prototyped in industry but has not yet been put into production.


Ships

Until the 20th century, naval weapons had a short range, so camouflage was unimportant for ships, and for the men on board them. Paint schemes were selected on the basis of ease of maintenance or aesthetics, typically buff (colour), buff upperworks (with polished brass fittings) and white or black hulls. Around the start of the 20th century, the increasing range of naval engagements, as demonstrated by the Battle of Tsushima, prompted the introduction of the first camouflage, in the form of some solid shade of gray overall, in the hope that ships would fade into the mist. First and Second World War

, pioneered by English artist Norman Wilkinson (artist), Norman Wilkinson, was used not to make ships disappear, but to make them seem smaller or faster, to encourage misidentification by an enemy, and to make the ships harder to hit. In the Second World War, the Royal Canadian Navy trialled a form of active camouflage, counter-illumination, using Diffused lighting camouflage, diffused lighting to prevent ships from appearing as dark shapes against a brighter sky during the night. It reduced visibility by up to 70%, but was unreliable and never went into production. After the Second World War, the use of

made camouflage generally less effective. However, camouflage may have helped to protect US warships from Vietnamese shore batteries using optical rangefinders. Coastal patrol boats such as those of the Royal Norwegian Navy, Norwegian, Swedish Navy, Swedish and Indonesian Navy, Indonesian navies continue to use terrestrial style disruptively patterned camouflage.


Aircraft

Aircraft camouflage faces the challenge that an aircraft's background varies widely, according to whether the observer is above or below the aircraft, and with the background, e.g. farmland or desert. Aircraft camouflage schemes have often consisted of a light colour underneath and darker colours above. Other camouflage schemes acknowledge that aircraft may be seen at any angle and against any background while in combat, so aircraft are painted all over with a disruptive pattern or a neutral colour such as gray. Second World War maritime patrol aircraft such as the Consolidated PBY Catalina flying boat were painted white, as aircraft generally appear dark against the sky (including at night), and hence are least visible when painted in as light a colour as possible. The problem of appearing dark against the sky was explored in the U.S. Navy's Yehudi lights project in 1943, using counter-illumination to raise the average brightness of a plane, when seen head-on, from a dark shape to the same as the sky. The experiments worked, enabling an aircraft to approach to within before being seen, whereas aircraft without the lights were noticed away. The higher speeds of modern aircraft, and the reliance on radar and missiles in air combat have reduced the value of visual camouflage, while increasing the value of electronic "Stealth technology, stealth" measures. Modern paint is designed to absorb electromagnetic radiation used by

, reducing the signature of the aircraft, and to limit the emission of infrared light used by infrared homing, heat seeking missiles to detect their target. Further advances in aircraft camouflage are being investigated in the field of active camouflage.


In fashion and art


Fashion and the "Dazzle Ball"

The transfer of camouflage patterns from battle to exclusively civilian uses is not recent. Dazzle camouflage inspired a trend of dazzlesque patterns used on clothing in England, starting in 1919 with the "Dazzle Ball" held by Chelsea Arts Club. Those attending wore dazzle-patterned black and white clothing, influencing twentieth-century fashion and art via postcards (see illustration) and magazine articles. The Illustrated London News announced

War protesters and fashionistas

In the US in the 1960s, military clothing became increasingly common (mostly Olive Drab, olive drab rather than patterned camouflage); it was often found worn by opposition to the Vietnam War, anti-war protestors, initially within groups such as Vietnam Veterans Against the War but then increasingly widely as a symbol of political protest. Fashion design, Fashion often uses camouflage as inspiration – attracted by the striking designs, the "patterned disorder" of camouflage, its symbolism (to be celebrated or subverted), and its versatility. Early designers include Marimekko (1960s), Jean-Charles de Castelbajac (1975–), Stephen Sprouse (using Warhol prints, 1987–1988), and Franco Moschino (1986), but it was not until the 1990s that camouflage became a significant and widespread facet of dress from streetwear to high-fashion labels – especially the use of "faux-camouflage". Producers using camouflage in the 1990s and beyond include: John Galliano for Christian Dior, Marc Jacobs for Louis Vuitton, Comme des Garçons, Chanel, Tommy Hilfiger, Dolce & Gabbana, Issey Miyake, Armani, Yves Saint-Laurent (brand), Yves Saint-Laurent. Companies closely associated with camouflage patterns include 6876, A Bathing Ape, Stone Island, Stüssy, Maharishi, mhi, Zoo York (company), Zoo York, Addict, and Girbaud, using and overprinting genuine military surplus fabric; others use camouflage patterns in bright colours such as pink or purple. Some, such as Emma Lundgren and Stüssy, have created their own designs or integrated camouflage patterns with other symbols.


Restrictions

Some countries such as Barbados, Aruba, and other Caribbean nations have laws prohibiting camouflage clothing from being worn by non-military personnel, including tourists and children. Civilian possession of camouflage is still banned in Zimbabwe.
