Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of actively changing their skin pattern and colours, whether for camouflage or for signalling. It is possible that some plants use camouflage to evade being eaten by herbivores.
MARPAT is a multi-scale camouflage pattern in use with the United States Marine Corps, designed in 2001 and introduced from late 2002 to early 2005 with the Marine Corps Combat Utility Uniform (MCCUU), which replaced the Camouflage Utility Uniform. Its design and concept are based on the Canadian CADPAT pattern. The pattern is formed of small rectangular pixels of color. In theory, it is a far more effective camouflage than standard uniform patterns because it mimics the dappled textures and rough boundaries found in natural settings. It is also known as the "digital pattern" or "digi-cammies" because of its micropattern (pixels) rather than the old macropattern.
The Battle Dress Uniform (BDU) is a camouflaged combat uniform that was used by the United States Armed Forces as their standard combat uniform from the early 1980s to the mid-2000s. Since then, it has been replaced or supplanted in every branch of the U.S. Armed Forces.
A combat uniform, also called field uniform, battledress or military fatigues, is a casual type of uniform used by military, police, fire and other public uniformed services for everyday fieldwork and combat duty purposes, as opposed to dress uniforms worn in functions and parades. It generally consists of a jacket, trousers and shirt or T-shirt, all cut to be looser and more comfortable than more formal uniforms. Design may depend on regiment or service branch, e.g. army, navy, air force, marines, etc. In the army branches, fabrics tend to come in camouflage, disruptive pattern or else green, brown or khaki monochrome, in order to approximate the background and make the soldier less visible in nature. In Western dress codes, field uniform is considered equivalent to civilian casual wear. As such, field uniform is considered less formal than service dress uniform, generally aimed at office or staff use, as well as mess dress uniform, and full dress uniform.
Disruptive Pattern Material (DPM) is the commonly used name of a camouflage pattern used by the British Armed Forces as well as many other armed forces worldwide, particularly in former British colonies.
Military camouflage is the use of camouflage by an armed force to protect personnel and equipment from observation by enemy forces. In practice, this means applying colour and materials to military equipment of all kinds, including vehicles, ships, aircraft, gun positions and battledress, either to conceal it from observation (crypsis), or to make it appear as something else (mimicry). The French slang word camouflage came into common English usage during World War I when the concept of visual deception developed into an essential part of modern military tactics. In that war, long-range artillery and observation from the air combined to expand the field of fire, and camouflage was widely used to decrease the danger of being targeted or enable surprise. As such, military camouflage is a form of military deception in addition to cultural functions such as political identification.
MultiCam is a camouflage pattern designed for use in a wide range of environments and conditions which was developed and is produced by American company Crye Precision. The pattern has found extensive adoption globally. Variants of it, some unlicensed, are in use with militaries worldwide, particularly with special forces/special operations forces units.
The New Zealand disruptive pattern material, also known as New Zealand DPM (NZDPM), was the official camouflage pattern on uniforms of the New Zealand Defence Force from 1980 until 2013. It was replaced with a new pattern called Multi Terrain Camouflage (MCU) which was exclusive to the NZDF. This was in turn replaced by the New Zealand Multi Terrain Pattern (NZMTP) from 2020.
The Marine Corps Combat Utility Uniform (MCCUU) is the current battledress uniform of the United States Marine Corps. It is also worn by Navy personnel assigned to Marine Corps units.
The Universal Camouflage Pattern (UCP) is a digital military camouflage pattern formerly used by the United States Army in their Army Combat Uniform. Technicians at Natick Soldier Systems Center attempted to devise a uniform pattern that would mask the wearer in all seasonal environments. Laboratory and field tests from 2003 to 2004 showed a pattern named "All-Over-Brush" to provide the best concealment of the patterns tested. All-Over-Brush was selected as the winner over ten other patterns. The disadvantage of an all-in-one pattern is that it is a combination of what is effective in many different environments and is less effective in a particular environment when compared to a specialized coloration designed specifically for that environment. The winning All-Over-Brush pattern was not used as the final UCP. Instead, U.S. Army leadership utilized pixelated images taken from Canadian CADPAT and US Marine Corps MARPAT, then recolored them based on three universal colors developed in the Army's 2002 to 2004 tests, to be called the UCP. While the pixelated pattern of the UCP is similar to the MARPAT and CADPAT camouflage patterns used by the United States Marine Corps and the Canadian Armed Forces, its coloration differs significantly. The final UCP was then adopted without field testing against other patterns.
The U.S. Woodland is a camouflage pattern that was used as the default camouflage pattern issued to the United States Armed Forces from 1981, with the issue of the Battle Dress Uniform, until its replacement in the mid to late 2000s. It is a four color, high contrast disruptive pattern with irregular markings in green, brown, sand and black. It is also known unofficially by its colloquial moniker of "M81" after the Battle Dress Uniform it was first used on, though this term was not officially used by the U.S. military.
Type 97 Service Dress were the military uniforms used by all branches of the People's Liberation Army (PLA) in both the People's Liberation Army Hong Kong Garrison and People's Liberation Army Macau Garrison beginning in 1997. These uniforms have since been replaced by the new Type 07 series of uniforms, which were unveiled in late June 2007 in conjunction with the 10th anniversary celebrations of the Transfer of sovereignty over Hong Kong.
Aircraft camouflage is the use of camouflage on military aircraft to make them more difficult to see, whether on the ground or in the air. Given the possible backgrounds and lighting conditions, no single scheme works in every situation. A common approach has been a form of countershading, the aircraft being painted in a disruptive pattern of ground colours such as green and brown above, sky colours below. For faster and higher-flying aircraft, sky colours have sometimes been used all over, while helicopters and fixed-wing aircraft used close to the ground are often painted entirely in ground camouflage. Aircraft flying by night have often been painted black, but this actually made them appear darker than the night sky, leading to paler night camouflage schemes. There are trade-offs between camouflage and aircraft recognition markings, and between camouflage and weight. Accordingly, visible light camouflage has been dispensed with when air superiority was not threatened or when no significant aerial opposition was anticipated.
The Canadian Disruptive Pattern is the computer-generated digital camouflage pattern developed for use by the Canadian Armed Forces. Four operational variations of CADPAT have been used by the Canadian Armed Forces: a temperate woodland pattern, an arid regions pattern, a winter operations pattern, and a multi-terrain pattern.
M1929 Telo mimetico was a military camouflage pattern used by the Italian Army for shelter-halves and later for uniforms for much of the 20th century. Being first issued in 1929 and only fully discontinued in the early 1990s, it has the distinction of being the first printed camouflage pattern for general issue, and the camouflage pattern in longest continuous use in the world.
Disruptive coloration is a form of camouflage that works by breaking up the outlines of an animal, soldier or military hardware with a strongly contrasting pattern. It is often combined with other methods of crypsis including background colour matching and countershading; special cases are coincident disruptive coloration and the disruptive eye mask seen in some fishes, amphibians, and reptiles. It appears paradoxical as a way of not being seen, since disruption of outlines depends on high contrast, so the patches of colour are themselves conspicuous.
Operational Camouflage Pattern (OCP), originally codenamed Scorpion W2, is a military camouflage pattern adopted in 2015 by the United States Army for use as the U.S. Army's main camouflage pattern on the Army Combat Uniform (ACU). This pattern officially replaced the U.S. Army's previous Universal Camouflage Pattern (UCP) as the official combat uniform pattern for most U.S. soldiers at the end of September 2019. The pattern also superseded the closely related MultiCam, a pattern previously used for troops deploying to Afghanistan.
German World War II camouflage patterns formed a family of disruptively patterned military camouflage designs for clothing, used and in the main designed during the Second World War. The first pattern, Splittertarnmuster, was designed in 1931 and was initially intended for Zeltbahn shelter halves. The clothing patterns developed from it combined a pattern of interlocking irregular green, brown, and buff polygons with vertical "rain" streaks. Later patterns, all said to have been designed for the Waffen-SS by Johann Georg Otto Schick, evolved into more leaf-like forms with rounded dots or irregular shapes. Camouflage smocks were designed to be reversible, providing camouflage for two seasons, whether summer and autumn, or summer and winter (snow). Distribution was limited to the Waffen-SS, ostensibly because of a patent, though variants were used by other units, including the Luftwaffe. Production was limited by shortage of materials, especially of high quality waterproof cotton duck.
Timothy R. O'Neill was a U.S. Army officer, professor and camouflage expert, who in 1976 invented Dual-Tex, the first pattern of what would later be called digital camouflage. He has been called "father of digital camouflage". O'Neill wrote two works of fiction. In 1979 he published The Individuated Hobbit: Jung, Tolkien, and the Archetypes of Middle-Earth.
