The ERDL pattern, also known as the Leaf pattern,[2] is a camouflage pattern developed by the United States Army at its Engineer Research & Development Laboratories (ERDL) in 1948.[3][4] It was not used until the Vietnam War, when it was issued to elite reconnaissance and special operations units beginning early 1967.[5][6]
The pattern consists of four colors printed in an interlocking pattern. It was initially produced in a green-dominant colorway, consisting of large organic shapes in olive green and brown, black 'branches' and light green 'leaf highlights'. Shortly after it was first fielded in Vietnam a brown-dominant scheme with the light green replaced by light tan was introduced.
