Universal Camouflage Pattern
The Universal Camouflage Pattern (UCP) is a digital camouflage pattern formerly used by the United States Army in their Army Combat Uniform.
Laboratory and field tests from 2002 to 2004 showed a pattern named "All-Over Brush" to provide the best concealment of the patterns tested. At the end of the trials, Desert Brush was selected as the winner over 12 other experimental patterns. The winning Desert Brush pattern was not used as the final Universal pattern. Instead, U.S. Army leadership utilized pixelated patterns of Canadian CADPAT and U.S. Marine Corps MARPAT, then recolored them based on three universal colors developed in the Army's 2002 to 2004 tests, to be called UCP with significantly less disruptive capability than either of its prior familial patterns. The final UCP was then adopted without field testing against other patterns.
Soldiers serving in Iraq and Afghanistan questioned the UCP's effectiveness as a concealment method. Some felt that it was endangering their missions and their lives. In response, the U.S. Army conducted several studies to find a modification or replacement for the standard issue pattern. In July 2014, the Army announced that Operational Camouflage Pattern would replace all UCP-patterned ACU uniforms by the end of September 2019. However, UCP remains in service in limited capacities, such as on some cold weather overgear and older body armor.
From May 2001 to June 2004, the U.S. Army universal camouflage trials were held, first to test terrain-specific patterns for woodland, desert, urban and desert urban environments, and later to develop a pattern that would mask the wearer in all environments.
In 2002, three patterns were developed, called All-Over Brush, Track, and Shadowline. 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.
There were 15 evaluations total, which took place at locations across the contiguous United States.
In late 2002, the camouflage patterns were rated on their blending, brightness, contrast, and detection by U.S. Army soldiers in daylight conditions. The samples patterns were prepared using inkjet printing for time-efficiency and cost-effectiveness. However, inkjet dyes are highly visible on near-infrared (NIR) night vision devices, so actual NIR evaluations could not be conducted; instead the colors of the patterns were adjusted to simulate how they would be viewed under NIR For the remainder of the phases, production printing with regular dyes and mechanical rollers were used.
Following phase I testing, the Shadowline pattern was eliminated, along with the urban and desert-urban color ways of All-Over Brush. All four of the Track patterns were accepted along with All-Over Brush's woodland and desert colorways.
