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, as well as making general aiming easier. 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.
In mathematics, a fractal is a geometric shape containing detailed structure at arbitrarily small scales, usually having a fractal dimension strictly exceeding the topological dimension. Many fractals appear similar at various scales, as illustrated in successive magnifications of the Mandelbrot set. This exhibition of similar patterns at increasingly smaller scales is called self-similarity, also known as expanding symmetry or unfolding symmetry; if this replication is exactly the same at every scale, as in the Menger sponge, the shape is called affine self-similar. Fractal geometry lies within the mathematical branch of measure theory.
A pattern is a regularity in the world, in human-made design, or in abstract ideas. As such, the elements of a pattern repeat in a predictable manner. A geometric pattern is a kind of pattern formed of geometric shapes and typically repeated like a wallpaper design.
Flecktarn is a family of three-, four-, five- or six-color disruptive camouflage patterns, the most common being the five-color pattern, consisting of dark green, grey-green, red brown, and black over a light green or tan base depending on the manufacturer. The original German five-color pattern was designed for use in European temperate woodland terrain. A three-color variation called Tropentarn is intended for arid and desert conditions; the German Bundeswehr wore it in Afghanistan.
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.
The Army Combat Uniform (ACU) is the current combat uniform worn by the United States Army, U.S. Air Force, and U.S. Space Force. Within U.S. Air Force and U.S. Space Force, it is referred to as the OCP Uniform, rather than the Army Combat Uniform.
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 to 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 specifically developed and is produced by American company Crye Precision. As a result of the pattern's effectiveness across disparate environments and regions, it has found extensive adoption globally. Variants of it, some unlicensed, are in use with armed forces worldwide, particularly with special operations units.
The IIFS was introduced in 1988, to serve as a fighting and existence carrying system—a possible replacement for the All-purpose Lightweight Individual Carrying Equipment employed and fielded by United States Armed Forces since 1973.
The helmet cover was first used by French soldiers during World War I.
Type 07 is a group of military uniforms used by all branches of the People's Liberation Army (PLA) of the People's Republic of China (PRC) and the paramilitary Chinese People's Armed Police Force. Introduced in 2007, the Type 07 uniforms replaced the Type 87 service uniforms used by regular units and the Type 97 Service Dress uniforms of the People's Liberation Army Hong Kong Garrison and the People's Liberation Army Macau Garrison. The Type 07 uniforms were first seen in late June 2007 during a celebration ceremony for the 10th anniversary of the Transfer of sovereignty over Hong Kong.
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.
Multi-scale camouflage is a type of military camouflage combining patterns at two or more scales, often with a digital camouflage pattern created with computer assistance. The function is to provide camouflage over a range of distances, or equivalently over a range of scales, in the manner of fractals, so some approaches are called fractal camouflage. Not all multiscale patterns are composed of rectangular pixels, even if they were designed using a computer. Further, not all pixellated patterns work at different scales, so being pixellated or digital does not of itself guarantee improved performance.

Disruptive coloration is a form of camouflage that works by breaking up the outlines of an animal, soldier or military vehicle 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.
Snow camouflage is the use of a coloration or pattern for effective camouflage in winter, often combined with a different summer camouflage. Summer patterns are typically disruptively patterned combinations of shades of browns and greys, up to black, while winter patterns are dominated by white to match snowy landscapes.
Xingkong, is a military camouflage pattern adopted in 2019 by all branches of the People's Liberation Army (PLA) of the People's Republic of China (PRC). Introduced in 2019, the Xingkong pattern replaced the Type 07 camouflage on the Type 07 service uniforms used by regular units. The new uniform and Xingkong camouflage were first seen in late September 2019 before the celebration ceremony for the 70th anniversary of the People's Republic of China.
The Netherlands Fractal Pattern (NFP) was developed as a collaboration project between the Netherlands Organisation for Applied Scientific Research (TNO) and the Dutch Ministry of Defence in order to replace all the camouflage patterns in use by the Dutch military.
