The OG-107, in the context of the United States Air Force, refers to a uniform that was adopted by the Air Force and other branches of the U.S. military in the 1960s. It was made of olive green cotton and consisted of a button-down shirt and trousers, similar to the Army’s OG-107 uniform. The OG-107 uniform was worn by Air Force personnel for various duties and was eventually replaced by the Battle Dress Uniform (BDU) in the 1980s.
