OCP is a U.S. Army term that stands for Operational Camouflage Pattern. MultiCam is the Army’s current OCP and is codenamed Scorpion.
However, as of October 2019, a variation of MultiCam/Scorpion known as Scorpion W2 was placed into service. Scorpion W2 employs the same geometric shapes as MultiCam/Scorpion. But Scorpion W2’s colours are darker and more pronounced (compare the difference in the image below).
