The ACU originally used the [[Universal Camouflage Pattern]] (UCP), which used a pixelated pattern of tan, gray and green (Desert Sand 500, Urban Gray 501 and Foliage Green 502) and was intended to work in desert, woodland, and urban environments.<ref name=Factsheet>{{cite web |title=Advanced Combat Uniform (ACU) |url=https://peosoldier.army.mil/FactSheets/PMSPIE/SPIE_SCIE_ACU.pdf |access-date=19 January 2011 |date=October 2010 |website=[[PEO Soldier]] |url-status=dead |archive-url=https://web.archive.org/web/20110927111626/https://peosoldier.army.mil/FactSheets/PMSPIE/SPIE_SCIE_ACU.pdf |archive-date=27 September 2011}}</ref> In 2010, the ACU received some improvements to pockets and such.<ref>{{cite web | url=https://soldiersystems.net/acu-improvements/ | title=ACU Improvements - Soldier Systems Daily | date=19 August 2009 }}</ref>
