The OG-107 uniform was introduced in 1952, and, succeeding the M1943 Uniform, it became the standard for use both in the United States and on overseas deployment by the beginning of the Vietnam War. As the Tropical Combat Uniform (jungle fatigues) became more plentiful in South Vietnam, they began to replace the OG-107 Uniform in combat units. A rough time line is that line infantry units from "standard" divisions (not airborne or Special Forces) began receiving jungle fatigues in the spring of 1966 and the OG-107 was slowly relegated to use in rear areas.
In the United States and foreign postings (outside of Southeast Asia), the OG-107 remained the standard uniform throughout the 1960s and 1970s. This is one of the longest issued uniforms by the US Military, seeing use from 1952 until the adoption of the poly-cotton blend OG-507 in 1978. Minor modifications were made to the uniform over time such as adding buttoned cuff slits in the mid-1960s.
