Universal Camouflage Pattern

The Universal Camouflage Pattern (UCP) is a digital military camouflage pattern formerly used by the United States Army in their Army Combat Uniform.[4][5] Technicians at Natick Soldier Systems Center attempted to devise a uniform pattern that would mask the wearer in all seasonal environments.[6] Laboratory and field tests from 2003 to 2004 showed a pattern named "All-Over-Brush" to provide the best concealment of the patterns tested.[6] All-Over-Brush was selected as the winner over ten other patterns,[7] It was observed at the time that the universal disadvantage of an all-in-one pattern meant compromise and lowered effectiveness in all environments versus a more effective coloration for each environment.[6] Further, the winning All-Over-Brush pattern was not in fact chosen as the final UCP.[6] Instead, U.S. Army leadership utilized pixellated images taken from Canadian CADPAT and US Marine Corps MARPAT, then recolored them based on three universal colors developed in the Army's 2002-2004 tests, to be called the UCP.[6] 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.[8][9] The final UCP was then adopted without field testing against other patterns.[6]

Soldiers serving in Iraq and Afghanistan questioned the effectiveness of the UCP in concealing them from enemy observation, and that the uniform was in fact endangering their missions and their lives.[6] In response, the US Army conducted several studies to find a modification or replacement for the standard issue pattern.[10] In July 2014, the Army announced that Operational Camouflage Pattern would replace all UCP-patterned ACU uniforms by the end of September 2019.[11][12][13][14] However, UCP does remain in service in limited capacities, such as on some cold weather overgear and older body armor.[1]

Initial patterns and colors
Main article: U.S. Army universal camouflage trials

Three patterns were developed, called All Over Brush, Track, and Shadow/Line.[15] For each pattern, there were four color combinations, which corresponded to a specific type of terrain, however, all four patterns used tan as their base color.[15] The three remaining colors were green, brown, and black for the Woodland pattern, dark tan, khaki, and brown for the Desert pattern, light gray, medium gray, and black for the Urban pattern, and dark tan, light gray, and brown for the Desert/Urban pattern.[15]

Test sites

There were fifteen evaluations, which took place at Fort Benning, Fort Polk, Fort Irwin, Fort Lewis, and Yakima, Washington.[15] The camouflage patterns were then rated on their blending, brightness, contrast, and detection by U.S. Army soldiers, during the daytime, and also at night using night vision devices.

Elimination of patterns

Following testing, the Shadow Line pattern was eliminated, along with the urban and desert/urban patterns of All Over Brush. All four of the Track patterns were accepted along with All Over Brush's woodland and desert patterns.[15]

Phases II and III

The patterns were then modified and tested alongside a newly introduced "Contractor-Developed Mod" pattern, Scorpion, developed in conjunction with Crye Precision. Near infrared testing determined that black, medium gray, and medium tan were the only colors that gave acceptable performance.[15]

Phase IV (system level)

All four remaining patterns, desert Brush, Scorpion, Woodland Track, and Urban Track were then tested alongside each other in urban, woodland, and desert environments.

Results

The desert Brush design received the best overall mean daytime visual rating. Contractor developed pattern received highest rating in woodland environments, but low ratings in desert and urban environments. Urban Track was generally the 3rd or 4th worst performer at each site, but was the best performer in nighttime environments. Infrared testing showed negligible differences in the performance of the four patterns. Natick rated the patterns from best to worst as: Desert Brush, Woodland Track Mod, Contractor-Developed Mod (Scorpion), and Urban Track.[16]

Color selection

The color scheme of the UCP is composed of tan (officially named Desert Sand 500), gray (Urban Gray 501), and sage green (Foliage Green 502). The pattern is notable for its elimination of the color black.[17] Justification given for the omission of black was that black is a color not commonly found in nature.[18] Pure black viewed through night vision goggles can appear extremely dark and create an undesirable high-contrast image.

Controversy

The U.S. Army incorrectly reported to the media that the basis for the UCP was the Urban Track pattern, which had been modified through the removal of black from the pattern and pixelated. Pattern comparisons subsequently established that the information provided by the U.S. Army was incorrect, and that the pattern was simply a three-colored version of MARPAT, a derivative of the Canadian CADPAT scheme. No evidence has been presented by the U.S. Army that the new UCP pattern had undergone proper field testing.[6] In tests conducted by the Natick Soldier Systems Center, results indicated that three other patterns did significantly better than UCP in desert and woodland environments.[19]

Following building criticism of the poor effectiveness of the pattern in most terrains like the Afghan and Middle Eastern theatres of operations, the use of the pattern was discussed within the U.S. Congress. A bill passed by Congress in 2009 ordered the Department of Defense to "take immediate action to provide combat uniforms to personnel deployed to Afghanistan with a camouflage pattern that is suited to the environment of Afghanistan."[20] In the interim the Army conducted a brief in-country test of replacements for use in Afghanistan that included "UCP Delta", a variant of UCP that added coyote brown, and the commercial pattern MultiCam, which had been created by Crye Precision based on the Scorpion pattern from 2002. MultiCam was quickly selected and issued to all troops deployed to Afghanistan.

Replacement
Main article: Operational Camouflage Pattern

In 2014, the United States Army announced the replacement of UCP.[21] On 31 July 2014, the Army formally announced that a modified version of the original Scorpion pattern, Scorpion W2, had been chosen as the new Operational Camouflage Pattern (OCP), which would begin being issued on uniforms in summer 2015. Authorization of UCP uniforms ended on 1 October 2019,[11][12][22] though still sees some limited usage on other gear such as some body armor and cold weather overgear.

As the Army began phasing out UCP, many state defense forces began adopting it as their uniform.[23][24]
