AVIATION GREEN UNIFORM--in SEP 1917 the "Forrestry" Green uniform of the U.S. Marine Corps was authorized for aviation officers as a winter working uniform. The earliest use of the uniform by enlisted men came in 1941 when chief petty officers designated as Naval Aviation Pilots were authorized to wear the uniform. In NOV 1985 Aviation Working Greens were authorized for wear by women in the aviation community.
