Camouflage History
Granite B: South Korea’s Digital Camouflage and the Replacement That Never Came
Sep
Since 2011 the armed forces of the Republic of Korea have worn one of the most widely issued digital camouflage patterns in the world. Almost every English-language reference calls it “Granite B”. The Korean soldier wearing it calls it nothing of the sort — and after nearly a decade of prototypes, Korea still has not managed to replace it. This is what the record shows.
A pattern with two names
In service, the pattern has no snappy Western designation. Korean reporting calls it 화강암 무늬 — “granite pattern” — or simply 디지털 무늬 전투복, the digital-pattern combat uniform: a name that describes the medium (pixels) and the garment (combat dress) rather than the design itself. In the legal text that put it into service, the Ministry of National Defence called it 디지털 5도색(화강암무늬) — the five-colour digital granite pattern.
The label “Granite B” belongs to reference works, collectors and the surplus market outside Korea. Camopedia, the standard camouflage reference, hedges even while using the term: the pattern is “reputedly termed Granite B” — reputedly, because no Korean document establishes it as an official name.
Where the “B” comes from is not documented in official records. The most coherent account comes from collectors: an initial trial variant circulated as “Granite A”, and the version adopted — after its colour balance was reworked, because the first version read too bright against Korean autumn and urban terrain — became “Granite B”. The account fits the difference between the trial and the production artwork, but it rests on collector knowledge rather than on a Korean document, and it should be read that way.
It also explains why the English term has become unavoidable in commerce: MegaCamo’s own catalogue lists the pattern as “Granit. B”, because that is how buyers outside Korea search for it. The name may not be official, but it is the working name. Korean documents regulate the colour composition of the uniform rather than naming the pattern.
Before the pixels: the blotch uniform
The pattern Granite replaced was not a plain colour. From 1991 the Korean armed forces wore a four-colour “blotch” pattern — 얼룩무늬 — a Korean design in the woodland family, which broke up the silhouette in the same way as the American battle dress of the period (Chosun Ilbo, 25 August 2014). It stayed in service for two decades, long enough to become the visual shorthand for the Korean soldier.
The blotch uniform was still being issued to soldiers as late as 2010, and it did not vanish when the digital uniform arrived. In September 2014 the ministry announced that the new combat uniform had been issued to every active-duty service member — while reporting of the same period still places the old blotch pattern in use in some formations (Kookbang Ilbo, 2 September 2014; Wowtv, 26 August 2014).
Five colours from Korean ground
The digital pattern rests on an official Ministry of National Defence research programme. Korean reporting in 2017 dated that study to 2008: the pattern then in use had been adopted on the basis of an MND research project, which meant that when the next uniform programme was launched, the pattern was already a decade old (Insight / Yonhap, October 2017).
The design rationale has been stated consistently since. Five colours were taken from what the Korean landscape actually contains — 흙 (soil), 침엽수 (conifer), 수풀 (undergrowth), 나무줄기 (tree trunk) and 목탄 (charcoal) — assembled in a pixel structure rather than in organic blotches. The Ministry gave that five-colour description when it presented the uniform in 2011, and Korean reporting repeated it as recently as December 2025. The palette is drawn from named features of Korean terrain, which is a different design logic from the single universal colour set the US Army adopted in the same decade: the two patterns belong to the same pixel generation, but one is not a recolouring of the other.
Two details are easy to miss. The first is sizing: the new uniform came with a size system rebuilt from 3D body scanning of Korean soldiers, which is why the pattern arrives in a size architecture with nothing in common with US sizing. The second is that the uniform was presented as all-season — one pattern for the whole year, in a country whose winter is severe enough that Korean infantry have long worn white oversuits over their uniform when the snow arrives.
A single pattern cannot solve that problem, and the ROK has never pretended otherwise. The oversuit remains the answer to snow.
Designing a national pattern: 2008 to 2010
The published record of how the pattern was actually chosen is Korean-language, official and rarely read outside Korea — and it is more interesting than the one-line version.
Demands to modernise the combat uniform go back to around 2004. The colour direction was settled by a Ministry research project whose results were reported in 2008; eight years later a Korean defence outlet could still write, accurately, that the pattern in service had been adopted on the basis of that 2008 study. The project proper began in May 2009, when the Ministry took delivery of an improvement plan for the new combat uniform.
What followed was a design competition inside the state. Korean accounts of the programme describe three pattern concepts going into the study — a rock-texture design (바위질감), a granite design (화강암) and a pine design (소나무). Granite won. An earlier and much narrower Korean pixel experiment sits behind it: a special-warfare uniform of the mid-2000s, described in Korean and collector sources as close to US Marine MARPAT and issued to the Special Warfare Command from 2007, is usually called the first pixel uniform to be worn by Korean troops.
The Ministry’s own newspaper, Kookbang Ilbo, documented the trials in August 2010. Field evaluation ran on real units rather than in a laboratory: the 21st Infantry Division, whose sector includes the Gachilbong outpost, a mechanised infantry battalion of the 20th Division, a coastal battalion of the 32nd Division, and the Capital Defence Command. Each soldier taking part received one special-warfare uniform and one new combat uniform, in two different pocket configurations — an Army proposal and a Ministry proposal — so that the wear test judged the cut as well as the cloth. By March 2010 the design, not merely the colours, had been fixed on the Ministry’s version, and the same month the Ministry signed a memorandum with the Ministry of Knowledge Economy on next-generation defence textiles.
The technical case was published with the trials. The Ministry’s newspaper reported an infrared reflectance of 900–1200 nm for the new uniform against 600–860 nm for the blotch pattern it replaced, and cited a 2009 study at Kookmin University which found the new pattern equal to the old one in daylight and better at night. It also noted the reasoning behind the artwork: around three quarters of the country is mountainous, and the pattern was drawn from the structure of granite rather than from photographs of vegetation. The textile package promised the same year was a list of functional finishes — stretch, antibacterial and anti-odour treatment, a water-repellent finish, wrinkle resistance and quick drying.

Into service: 2010 to 2014
The dates are worth stating carefully, because English-language sources compress them. Trial issue to units began in September 2010, and the Ministry published the formal proposal to replace the 1991 blotch uniform with the five-colour digital pattern in January 2011. The decree doing so was promulgated on 24 May 2011, with a three-year transition clause allowing the old pattern to be worn out.
The Ministry presented the finished uniform at a briefing on 29 September 2011, and issue began the following month, unit by unit. By September 2014 the ministry’s own newspaper could report that the new uniform had been issued to all active-duty personnel (Kookbang Ilbo, 2 September 2014).
References that date the pattern to “2010” are describing selection, not the first uniforms on a soldier’s back. It is a fair shorthand and a poor chronology — and it is worth remembering the next time a Western source gives a single year for a pattern that took five years to develop and three more to issue.
The uniform was not only a pattern. Yonhap reported in September 2011 that the size system had been rebuilt from a 3D scan of 324 soldiers across 17 combat postures, producing 44 jacket sizes and 40 trouser sizes. Whatever else the programme achieved, it produced a Korean uniform cut for Korean bodies.
Who else wears it: marines, sailors and reservists
Camopedia’s summary is that the pattern is used by the Army, the Navy and the Air Force “although not the Marines” — and the exception is the interesting part.
The Marine Corps took its own digitally patterned combat uniform, approved by the Ministry in December 2010 and issued to recruits from September 2011. Donga Ilbo reported a five-tone wave pattern rather than the granite pixel structure: from a sandy base with conifer, undergrowth and tree-trunk tones, three of the granite greys and browns were replaced by bluish grey, reddish grey and blue-black, judged closer to the sea, the tidal flats and the rocks of the Korean coast. The same report notes two distinctive details, an octagonal cap button and a removable red name plate.
The Navy’s own divergence came later and was driven by working conditions at sea. Korean reporting in February 2021 described a new shipboard uniform on a five-tone digital pattern — navy, blue, khaki, black and grey — replacing three separate garments, the marine combat dress, the patrol-boat dress and the submarine dress. The Ministry’s newspaper presented it as a practical change for crews working in confined, wet and hazardous spaces. Reporting a few months later described an aramid, flame-resistant fabric chosen after burn incidents at sea, and noted that the cost of the change attracted criticism.
The pattern prescribed for reserve forces and for Korean soldiers serving in US formations is not set out in the Ministry’s published material.
The uniform that was too hot, then too flammable
The 2011 uniform’s reputation took its first hit quickly: soldiers called it the 찜통 군복 — the steam-cooker uniform — and complained about heat and breathability. The response was a textile change, and in June 2019 YTN put the old and new fabrics through comparative burn tests.
The results were uncomfortable. Cotton content in Korean combat fabric had fallen from 100 per cent to 50, then 35, then 32 per cent; cotton was then replaced with rayon, and the polyester share was pushed as high as 78 per cent. In the tests, the whole new sample was engulfed in flame within ten seconds and embers persisted for more than a hundred seconds, while the older, cotton-rich fabric burned more slowly and — critically — produced no molten synthetic drips. The combat-uniform specification, YTN reported, contained no flame-retardant (방염) requirement at all.
A serving official quoted in the piece set out the trade-off plainly: after soldiers complained that stiff fabric was noisy and therefore a concealment problem, suppliers moved to a softer, more breathable blend — and that blend is what the tests measured. A national textile research institute proposed nylon-based no-melt, no-drip materials of the kind used by US forces, but raising the cotton content again would have meant returning to the very specification soldiers had rejected.
Six years later the gap was still there. Figures presented to the National Assembly in October 2025 put the number of service members issued with flame-resistant combat clothing at 49,700 across the armed forces — a small fraction of those in uniform — while the standard combat uniform continues to carry no flame-retardant requirement.
This matters to the Granite story for one reason: the pattern and the uniform are separate problems. The pattern has been the stable part. The fabric has been the argument.
The replacement that never happened
In October 2017 the Army’s leadership placed the uniform inside a much larger modernisation story. “Warrior Platform” (전사플랫폼) was announced as one of five “game changers”, and the combat uniform was to be redesigned in colour, material and cut — including the placement of name tapes, rank insignia and patches. A research tender for a new combat-uniform pattern, design and applied material followed in November 2017. The stated reasons were domestic rather than imported: a pattern designed under the 2008 study, a battlefield moving into urban terrain, and a wish for a distinctly Korean Army identity.
The prototypes followed. In 2019, photographs of the candidate patterns circulated in Korean defence circles: three families, each in several variants — 호랑이 (Tiger), 강인한돌 which translates best as “Strong Rock”, and 태극 (Taegeuk) — shown against reference photographs of the existing granite pattern. The project brief was explicit that the uniform itself was being replaced along with the pattern.
| Family | Variants shown | What happened to it |
|---|---|---|
| 호랑이 — “Tiger” | Four variants, the last two revised after Army feedback | Prototype worn by the Army Chief of Staff in July 2019; never adopted |
| 강인한돌 — “Strong Rock” | Three variants, the last two revised after Army feedback | Never adopted |
| 태극 — “Taegeuk” | Two variants | Never adopted |
| 화강암 — “Granite” (in service) | Shown as the baseline for comparison | Still the working uniform in 2026 |
In July 2019 the Army Chief of Staff appeared at the send-off of the 11th Hanbit Unit contingent wearing a Tiger-pattern prototype, which the Korean press read as a signal of the eventual winner. It was not. Six and a half years later there is still no selected replacement pattern.
The change keeps stalling for three reasons that are difficult to separate: cost, cycle time and politics. When the Ministry was reported in December 2025 to be reviewing a change of uniform design, the trigger was not camouflage performance. It was image. After the martial law declaration of 3 December 2024, footage of uniformed troops entering the National Assembly and the election commission building had damaged the military’s public standing, and a new uniform was floated as one element of refreshing it, under a task force set up in the name of constitutional government innovation (Chosun Ilbo, 15 December 2025; Segye Ilbo, 16 December 2025).
Reporting on 15 and 16 December 2025 put the decision in early 2026. The same reporting carried a sobering internal frame: the transition from the blotch pattern to the current digital uniform took about five years to develop, and, as one military official put it, “improving the combat uniform should be reviewed according to military needs, but there is also a burden and reluctance about it being pushed forward in connection with political controversy.”
A second driver was named in the same reporting: the North Korean army’s fielding of digital uniforms in imitation of the Korean one, including in airborne units. Which brings us to the most interesting part of the story.
The North Korean question
North Korean personnel in pixel uniforms closely resembling the Korean pattern appeared at the parade marking the 75th anniversary of the Workers’ Party on 10 October 2020, and again at the 8th Party Congress in January 2021. The resemblance was close enough that Korean newspapers printed the two uniforms side by side.
In June 2021 the Ministry of National Defence told reporters it could not rule out that Korean combat-uniform fabric had reached the North through China. The reporting described counterfeit Korean uniform items sold on Chinese cross-border platforms — including children’s clothing made from the same fabric — and a 2012 press account, cited at the time, in which traders bought samples of the newest Korean uniform in Seoul’s Namdaemun and Dongdaemun markets and mass-produced copies in Guangzhou for export to the North. The Ministry convened its first civil–government–military consultative meeting on 30 June 2021 with the environment ministry, the police, customs, the four largest second-hand marketplaces and used-clothing export and recycling firms, and said it had suppressed about 160 cases of illegal trade in counterfeit military goods the previous year (Munhwa Ilbo, June 2021).
The temptation is to conclude that Korea wants a new pattern because its own has been copied. That conclusion circulates — it has been asserted in Korean defence forums by a self-declared serving officer — and it is intuitive. But it is not what the record says. The Ministry has acknowledged the diversion as a possibility; it has never presented it as the reason for the new-uniform programme, and the December 2025 reporting attributed the push to image and identity instead.
The counter-argument also deserves recording, because Korean soldiers and commentators have made it: a pattern can be copied from photographs, and if an adversary is determined enough, the original artwork is not needed. Retiring a functioning pattern to defeat a copy may be an expensive way to answer a question that is really about identification, not concealment.
Desert colourways and the export record
Collectors will also meet the pattern in colourways that are not Korean issue. A desert version circulates in surplus and identification circles, usually linked to Gulf or Southeast Asian users, and the Republic of Korea has a well-documented habit of exporting its uniforms and equipment alongside its defence industry.
The accounts naming those countries rest on market listings, photographs and collector identification, not on procurement documents, and no acquisition record for any of them has been produced. Colourway names travel faster than contracts do.
Why it still matters
The significance of this pattern is not only Korean. It is one of the most widely issued digital patterns of the last fifteen years, worn by a conscript force of hundreds of thousands, and it belongs to a small group of 2000s pixel designs whose differences are far more interesting than their similarities.
It is also a useful reminder of something the online camouflage world tends to forget: a pattern is not only a design. It is a research programme, a textile specification, a procurement cycle and — as Korea’s case shows — sometimes a political object. The soldiers wearing it do not choose between colourways. They wear what survives the process.
If you are here for the pattern rather than the policy, MegaCamo carries it as reproduction cloth: the Granite B hooded t-shirt and the North Korean Granite bomber, two colourways of the same pixel family.
