Camouflage(Meisai) is to deceive the enemy's eyescamouflageOne of the technologies, on the surfacePainting,stainingEtc.patternIs.Camouflage by painting equipment etc.Camouflage painting, Camouflaged clothing (especiallyCombat uniform)Camouflage clothingSay.

There are many ways to camouflage, but the typical one is camouflage.When used for clothing, it is called camouflage clothing.

A pattern drawn with multiple colors is called a "split camouflage", and a camouflage that can be painted with a single color and has no pattern is called a "monochromatic camouflage".

In the case of ground troops, colors such as dark green, navy blue, and brown are often used.In many cases, several colors of mottled spots, spots, and stripes are used according to the vegetation and weather conditions of the area.Land vehicles and military aircraft whose main mission is to fly at low altitudes perform similar camouflage.For ships in the open ocean and aircraft in maritime nations with the background sky or sea, the camouflage is simpler to blend in with the surrounding scene.For example, the visibility is reduced by offsetting the shadows by painting the parts that are exposed to light with dark colors and the shaded parts with light colors.CountershadingThere is.

In snowy areas, it may be white, light gray or solid white, and in nighttime operations, it may be a solid color, which is not called "camouflage" in the general sense, but "camouflage". "" Means "dressing (being) in the surrounding scene", so these are also "camouflage (painting)" by definition.

Camouflage is also important for hunting purposes, although the demand group is different.By preparing clothes that match the vegetation of the hunting ground, it is not easily visible to the prey, and by specializing in the location, it is possible to exert an effect that is superior to the camouflage effect in various environments for military use.It should be noted that there is a regulation for use in Japan to prevent accidental fire.


Until modern times, it was important for military painting to "stand out" before "hidden."In an era when there was only a visual means of identification, to show off the strength of the enemy and allies, the strength of the army, and the position and authority of officers within the army.Military flag,armor,Military uniformWas required to have an eye-catching color scheme and design.In pre-modern shootouts, when guns were still developing, "prominent" in front of the enemy never meant "one-sided shooting."

The first camouflage effect in modern military uniformBritish Army 1848 ToPeshawarMatched to the local colors in the battle atkhakiIt is said that it started with the use of military uniforms.In Persian, khaki means "dusty brown."However, it was during World War I that the camouflage pattern that was designed in earnest was adopted.French armyIt is said that it was.1914 At the end of the period, a painter who worked in the French artillery unit devised a camouflage for cannons and tanks.The effect of camouflage was confirmed, and the military1915 After that, a camouflage camouflage corps was formed, and it is said that painters and designers were appointed to devise the pattern.After that, the British army1916 At the beginning of the event, a similar unit was formed and organized.Camouflage has become more important, especially as the reconnaissance power of aircraft has improved and the destructive power of weapons has improved.Second World WarSince then, it has been generally adopted by the military of each country.The most successful camouflage is the white overalls worn in winter snowfall areas, which have been extremely effective and have been adopted in many countries with little opposition.

Military use

Uniform / combat uniform

World War IAt the beginning of the war, some troops used flashy colored combat uniforms, but during the war, each countrykhakiI came to use military uniforms of inconspicuous colors such as systems.The first time I used the current camouflage uniform in earnestSecond World WarGermany inWaffen SSIs.Other Italian paratroopers of the same period, US Army[1] It was also used as part of the Marine Corps.In addition, camouflage patterns (helmet covers, smocks, pullovers, hoodies, etc.) are used mainly by paratroopers and repellents in the United Kingdom, the Soviet Union, and Hungary.JapaneseArmy paratroopers(Giretsu Airborne Corps) Then, in a single color combat uniforminkThere is an example of trying to obtain a camouflage effect by drawing a pattern with.In recent yearsterrorism,City battleGray or white forbuildingGeometric camouflage (urban camouflage) based on (to blend in with the color of) and camouflage aimed at effects on various terrains (CPU,MulticamEtc.) are adopted in each country.In addition, digital camouflage, which uses a computer to determine a highly effective color scheme and composes a pattern with fine dots, is becoming mainstream.


Second World WarEffectively utilized tanks inNazi GermanyThen, although it was the basic paint color at the beginning of the war, it was used as a camouflage color on the North African Campaign, but it was shown that it is also effective on the European Campaign, and there is a history that the basic color was changed to in the latter half. ..In addition, a three-color camouflage with two colors on top is applied on the front line, and from above during winter snowfall.limeA winter camouflage was applied by applying an aqueous solution of.U.S. Forces TheVietnam WarUntil the timeOlive drabAlthough it was a single color, it adopted a four-color camouflage based on the 1970s.However, due to cost and standardization, in the 4sNATOI have switched to the same three-color camouflage as the military.Gulf War-Iraq warThen, sand-based painting was applied according to the site.In recent yearsCity battleGeometric camouflage suitable for is also available.


The main purpose of camouflage for buildings is to protect buildings, runways, reservoirs, gas tanks, etc. that cannot be hidden underground from air raids.A famous example is during World War IISeattleWas in the suburbsBoeing CompanyBecause the huge flat roof of the factory stands out, it has been given a split camouflage that is subdivided into light and dark colors so that it looks like a residential area with no strategic value when viewed from the sky.

In addition,Bunker,Special fire pointIn some cases, windows were drawn to disguise the building as a private building.

Ships / ships

The main purpose of camouflage on a ship is not to "make it difficult to see" from land or aircraft, but to make the enemy misunderstand the size, speed, direction of travel, distance to the ship, and so on.This is because it is difficult to express the invisible phenomenon of ships on the ocean.

The idea for the camouflage of ships appeared in the late 19th century, but it was realized in World War I.1917 Around the time of Germany during World War IsubmarineAs the damage caused by the disease increased, band-shaped camouflage and wave front camouflage began to appear.In particular, when the chimney and mast remain as they are, the vertical lines are erased and diagonal camouflage is applied.

Many colors were used in the early days, but after World War I, black and gray (Battleship Gray), It has subsided in blue.It was a response to the fact that German submarines were attacking with a periscope equipped with a color light filter (a filter that reduces color to monochrome) as a method of detecting camouflage, eliminating the influence of color.Paint the entire ship in gray, make it difficult to distinguish from the background, deceive the speed and distance measurement to the ship, and make the shadow of the ship similar to a ship of different size such as a cruiser or a battleship, so that the distance can be misunderstood. I have also said.

In World War II, the aircraft carrier was also painted with camouflage.When viewed from the sky, the ship type of the aircraft carrier is immediately known, but a camouflage of a geometric pattern (basically, all countries use dark colors such as green and black) is applied on the flight deck. This is because even if it is discovered as a ship, it is not possible to determine what kind of ship it is, which is expected to deceive the outline.The US Navy devised a cloud-shaped camouflage (Ms.2 / 32D) with two gray colors mixed with black.MissouriIt was also used for battleships such as.In the Royal NavyMountbatten pinkWas used for a while.Japanese Navy OfZuikaku (aircraft carrier)Painted the hull and deck with shadows and structural designs in order to mislead ships other than aircraft carriers.

After World War II, it became the mainstream to paint the whole in gray.

The typical camouflage styles of ships are as follows.

  • Brush type
  • McKay
  • Hertz Org style
  • Tok type
  • Warner type

Aircraft / military aircraft

It is the first time since the Spanish War that the camouflage painting of airplanes has been taken seriously.Until World War I, many fighter pilots came from upper classes such as aristocrats.Chivalry spiritPlay a one-on-one aerial battle according to the rules and leave the heroic story to posterityduelThe side as was strong.For this reason, he often drew large troop emblems and coats of arms on flashy paint.

In World War II, when moving from individual warfare to systematic team warfare, research on camouflage suitable for airplanes was conducted.HoweverIdentification friend or foeWas underdeveloped, and when it became a melee, misfires from friendly aircraft occurred frequently, so it was big.Nationality markMeasures were taken to improve visibility by drawing identification patterns such as invasion stripes (black and white painting on the fuselage and wings of Allied aircraft).Also flashyNose artWas also tolerated because of morale.

The camouflage for a full-scale aircraft isVietnam WarIt develops from that time.In the Vietnam War, there were many battles within the visual range, so the damage to the flashy painted aircraft was not negligible in the US military.Therefore, the mission is mainly at low altitude.Attack aircraftFor example, a camouflage paint similar to that of a ground unit that blends into the ground when viewed from above is a low visibility of the blue-gray system that prevents it from being found as close as possible to a fighter whose main air superiority fighter is at high altitude. Low visibility (low visibility) painting has come to be performed.Also, during World War II, there was a compromise between the upper part being the former and the lower part being the latter, but when viewed from the side, it was rather conspicuous, so there were few examples of adoption.The unit mark and aircraft number are also drawn in low-visi paint so that they are not noticeable in the distance.

In countries such as Japan, which are surrounded by the sea, the aircraft may be decorated with blue-based offshore camouflage.


Camouflage clothing

Japan Ground Self-Defense ForceThen, is the camouflage pattern to give an image of intimidation and war colors?Olive drab(OD) was often used, but in the latter half of the Showa period, camouflage was also used for combat uniforms.However, the camouflage pattern, which is said to have been designed based on the bamboo bush in Hokkaido, was conspicuous at short distances, except in some areas.In particular, the light green part of the base color began to develop a light blue color during washing, and it was unpopular that it was easily detected by the enemy.

Therefore, in the Heisei period, new camouflage patterns began to be studied.1992 ToCamouflage type 2The provision of combat uniforms (commonly known as new camouflage) (later camouflaged work clothes) has begun.The new camouflage was designed by computer-processing various mountain landscapes in Japan and dot-forming camouflage patterns that match the climate of Japan, and its performance was significantly improved compared to the old camouflage.Combat uniforms and work clothes have now moved to this new camouflage, and old camouflage and OD are rarely seen.

2004 from(I.e. OfSummerwaWhile each country uses clothing that adopts a camouflage pattern for desert areas when dispatching the Self-Defense Forces to Japan, the Self-Defense Forces dare to wear clothing with this green camouflage pattern (heat protection) in order to emphasize that "Japan's peace reconstruction unit is stationed". A custom-made item called 4 types of clothes) was adopted.In Islamic countries such as Iraq, green is considered a noble color, and based on that, it is said that it means that it is not a combat unit.

The Ground Self-Defense Force, which has not used desert camouflage in this way, is now using desert camouflage from the perspective of preventing snipers.This camouflage follows the pattern of the Type 2 camouflage and changes the color for the desert, and has been used since 2010 by the units deployed in Djibouti to escort the Maritime Self-Defense Force patrol aircraft.

Japan Air Self-Defense ForceIn the high-firing unit (air defense unit) and the base guard, camouflage uniforms different from those of the Ground Self-Defense Force (different colors of the old type camouflage of the Ground Self-Defense Force) are adopted.In contrast to the GSDF's new camouflage, which is a collection of fine dots that emphasize close quarters combat, the ASDF's camouflage is a large, brownish pattern that emphasizes reduced visibility from a long distance. Since 2009, a digital camouflage based on gray has been adopted as a successor.In addition, the ASDF was the first Self-Defense Forces to adopt a 6C desert (chocolate chip pattern) desert camouflage uniform during the Gulf War to prepare for the rescue operation of Japanese nationals.This camouflage uniform was never used because it was not actually dispatched, but when dispatched to Iraq later, unlike the Ground Self-Defense Force, it used a desert camouflage uniform of 3C desert (coffee stain pattern).

Flight suitUses a dark green one,Dispatched anti-piracy action aviation corpsToTan colorFlight suits are provided.


The vehicle of the Ground Self-Defense Force was originallyOlive drabIt was painted in a single color, but in the 1990s, large camouflage painting using brown or black began to be applied.Most of the vehicles of the current Ground Self-Defense Force (excluding trucks) are painted with this camouflage, but when dispatched to Iraq, it is emphasized that it is "Japanese peace reconstruction unit stationed" as well as camouflage uniforms. Therefore, I was dispatched after repainting with OD single color.The Air Self-Defense ForcePatriot missile,Light armored vehicleAlthough it owns a fighting vehicle like this, it is painted in OD single color without camouflage painting like the Ground Self-Defense Force.


Air Self-Defense Force aircraft are painted in a single gray low-visi paint that is effective in the air and while parked.F-15,F-4Ocean camouflage that is effective when flying over the sea (etc.)F-2, F-4,UH-60J) Forest camouflage that is effective when flying at low altitude (RF-4) Is adopted.

The Maritime Self-Defense Force used three colors of offshore camouflage to assimilate the nose with black, the upper surface with the reflection of the sea (white), and the lower surface with the sky (light gray), following the U.S. Navy. If you change to painting, fixed wing patrol aircraft (P-3C,P-1) Is a single gray low-visit paint, patrol helicopter (SH-60JFor example, the low-visit paint has been changed to a low-altitude offshore paint with only the underside white, and the rescue aircraft has been changed to dark blue and gray offshore camouflage.

Ground Self-Defense Force aircraft are basically the same camouflage paint as vehicles, but some aircraft (EC-225LP,LR-2) Is a unique four-color paint with black around the nose and exhaust port, light gray on the bottom, blue on the top, and white in the middle.

But,1960 eraSubsequent artists ignore the origin of military origin, or conversely anti-warMetaphorAs a result, he boldly incorporated the unique technique and concept of camouflage pattern, "conceal and distort" into his work.

Camouflage clothing gradually became popular as everyday wear.Durable and cheap combat uniforms sold by the U.S. military are first hunted in the United States and other countriesHunterAfter finding a market among them, the armies of each country made regular surpluses, so the market was further expanded, especially in the victorious countries where there was little dislike of war.

In the 1960s, it became more and more common to wear combat uniforms as everyday clothes, not just camouflage uniforms.VVAWSuch asAnti-war activistAre anti-warsymbolI was wearing this as.After the end of the Vietnam War, camouflage uniforms became popular in place of olive drab combat uniforms.
