The OG-107 was the basic work and combat utility uniform (fatigues) of all branches of the United States Armed Forces from 1952 until its discontinuation in 1989.
The OG-107 was superseded by the Battle Dress Uniform (BDU) throughout the 1980s, and was also used by several other countries, including ones that received military aid from the United States.
In the United States and foreign postings (outside of Southeast Asia), the OG-107 remained the standard uniform throughout the 1960s and 1970s.
Minor modifications were made to the uniform over time such as adding buttoned cuff slits in the mid-1960s.
The only change of any real significance was the "clipping" of the pocket flaps on the shirt, so that they no longer appeared rectangular.
The "Type III" is the most common model and can be split into two versions based on the time of manufacture and material.
A winter field uniform made of heavier weight wool (or wool–nylon blend) was also introduced in 1951.
They were typically worn with an ascot scarf by the missile launch crews, with the color varying by squadron - instructors at Vandenberg Air Force Base wore yellow or orange scarves.
Missileers typically wore them when on duty in the Launch Control Center, though the popular MA-1 Flight Jacket was also worn as the capsule was usually somewhat cold.
