The ERDL pattern, also known as the Leaf pattern was developed by the US Army at its Engineer Research & Development Laboratories (ERDL) in 1948. It wasn't used until the Vietnam War, when it was issued to elite reconnaissance and Special Forces units beginning early 1967.
The pattern consists of four colours printed in an interlocking pattern. It was initially produced in a green-dominant colourway, 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.
