US Camouflage Patterns

A variant of the standard M1942 reversible spot pattern jungle camouflage is seen here, printed on water-repellent fabric and constructed as a poncho/shelter half. As with the jungle pattern clothing, the poncho is reversible from a green dominant to a brown dominant scheme.

In 1948, the US Army Engineer Research and Development Laboratory (ERDL) designed a general purpose jungle camouflage consisting of mid-brown & grass green organic shapes with black "branches" on a lime green background. This pattern, often copied and still in usage today by other nations, is generally referred to as the ERDL pattern. Initially shelved, the pattern was tested again by the Army between 1963 and 1967, and began seeing limited service with special military units deployed to Vietnam beginning in 1968. It was highly favored by the US Marines in Vietnam, and was also obtained in limited quantities by Australian and New Zealand special forces deployed there. The original ERDL pattern is predominantly green and is often considered a "lowlands" pattern, referring to its suitability for application as camouflage in the lush, lowland regions of Southest Asia.

Also releasted in 1968 was a predominantly brown variation of the ERDL pattern. This version is often considered a "highlands" pattern, referring to its suitability for application as camouflage in the rocky, mountainous regions of Southeast Asia.

The original slant-pocket M1967 model jungle uniforms were only intended for usage by US military personnel deployed to Southeast Asia during the Vietnam War. Once the war ended, the original ERDL uniforms saw only scattered, unofficial usage by the US special operations community. Beginning in 1979, however, the DOD again reconsidered camouflage uniforms for issue to military personnel, and designed the Hot Weather Uniform (in a slightly varied cut from the Vietnam era jungle uniform) utilizing surplus stocks of green and brown dominant ERDL camouflage. Subsequent production of the textiles for this uniform saw a distinctive color change to the ERDL pattern, creating what has come to be known among some historians as "transitional ERDL" or "ERDL 2nd generation." This pattern features mid-brown & grass green organic shapes with black "branches" on a khaki background. This uniform was primarily distributed to members of the Rapid Deployment Force and the USM (along with some special operations personnel), but was officially only in production from 1979 to 1981.
