Authorized by the Chief of Staff, U.S. Air Force, Oct. 12, 1980. Before Jan. 6, 1986, the ribbon was awarded to Air Force and Air Force Reserve members credited with completion of an overseas tour on or after Sept. 1, 1980. Air Force and Air Force Reserve members serving as of Jan. 6, 1986, or later are entitled to reflect all Air Force overseas tours credited during their career. A service member may wear both the long tour and short tour ribbons if they have met the ribbon's eligibility requirements. The short tour ribbon takes precedence over the long tour ribbon when both are worn.
