This much-maligned camouflage pattern was widely issued and used by the US Army between 2005 and 2019. In 2010, soldiers deploying to Afghanistan were authorized to use Multicam as the “Operation Enduring Freedom Camouflage Pattern” (OEF-CP, source: https://www.army.mil/article/35184/soldiers_deploying_to_afghanistan_to_get_new_multicam_uniforms_boots_gear). In 2014, UCP was officially discontinued, to be replaced by a derivative of the very Multicam-like Scorpion pattern, termed the “Operational Camouflage Pattern” (OCP, source: https://www.military.com/daily-news/2014/05/23/army-selects-new-camouflage-pattern.html). All UCP items were to be phased out by October 2019 (source: https://www.army.mil/article/228411/acu_pattern_officially_retired_new_uniform_improvements_on_the_way).
Army Combat Uniform (ACU):
No longer in collection. This was patched to a soldier from the 101st Airborne Division and is the earlier non-flame resistant type. Concerns over improvised explosive devices caused soldiers to adapt existing flame-resistant uniforms, originally for vehicle crews and pilots, for combat while flame resistant versions were being made.
Extreme Cold Weather System (ECWS):
Gen II Later 3 Softshell Jacket:
Part of ECWS system. Synthetic, lightweight fabric. Has sticky external sided velcro “patch” attached to right shoulder velcro. No longer in my collection.
