Global War on Terrorism Service Medal Ribbon The Global War on Terrorism Service Medal (GWOTS) is a decoration of the United States Armed Forces presented to members of the U.S. military who have served in the War on Terror from September 11, 2001 to a yet to be determined date. To be eligible, service members must have served at least 30 consecutive or 60 cumulative days within an authorized anti-terrorism campaign. Service time may be waived when a service member participated in active combat, required medical evacuation after having been wounded or posthumously for any service member who dies from combat or non-combat wounds while in the line of duty. The designated operations for the GWOTS are as follows: Airport Security Operation, Operation Enduring Freedom, Operation Noble Eagle and Operation Iraqi Freedom. The Global War on Terrorism Expeditionary Medal is a similar award, with the primary difference being that it is awarded for service on foreign shores, while the GWOTS is generally awarded for service within the United States.
