To be awarded the Global War on Terrorism Expeditionary Medal a military service member must perform duty in a deployed status and must participate in designated anti-terrorism operation for a period of either 30 consecutive or 60 non-consecutive days of duty. For those who were engaged in combat, killed, or wounded in the line of duty, the time requirement is waived. The term "deployed status" indicates either temporary or permanent orders to a duty station outside the borders of the United States of America with such duty being in direct support of anti-terrorism operations. For a service member to receive the Global War on Terrorism Expeditionary Medal, the deployment must also have taken place in a nation which is currently recognized as a base for anti-terrorism operations by the United States Department of Defense.
On 30 April 2005, the Global War on Terrorism Expeditionary Medal was discontinued for service within Iraq and Afghanistan, such service now being recognized with the Iraq Campaign Medal and Afghanistan Campaign Medal. Personnel who received the GWOT-EM for previous service in these two regions may elect to exchange the GWOT-EM or retain the original award.
The GWOT-EM is a Defense Department expeditionary medal. Award of this medal does not prevent award of other types of recognition (such as decorations) normally associated with deployment. This medal may be awarded posthumously.
