The Pentagon has expanded the criteria for the Global War on Terrorism Expeditionary medal to include the U.S. campaign against ISIS in Libya.  The geographic criteria for the medal highlights the extent of the American operation to remove ISIS from the Libyan city of Sirte. The U.S. military operation to liberate Sirte from ISIS was conducted from Aug. 1, 2016 until Dec. 19, 2016, and authorized under the Obama administration. The operation was  dubbed Operation Odyssey Lightning. Service members who participated in Operation Odyssey Lightning from Aug. 1 to Dec.19, 2016 — the date Libya ended operations in Sirte, are eligible for the Global War on Terrorism Expeditionary medal.
