The Air Force Overseas Long Tour Service Ribbon is issued for completion of a standard overseas service assignment greater than two years in length with additional awards denoted by oak leaf clusters. Long tour credit is awarded for completion of a prescribed overseas long tour (2 years) by Air Force Instructions, or to any member assigned to a United States or overseas location who is subsequently sent under temporary duty orders (to include combat tours) for 365 or more days within a 3 year time frame.
