For U.S. forces the eligibility for the Non-Article 5 Medal for service with the ISAF is thus: those who are members of units or staffs as set out in the Joint Operations Area taking part in operations in Afghanistan. The area of eligibility is delineated by ISAF's political boundaries. The service must be a minimum of 30 days either continuous or accumulated, from 1 June 2003 to 31 December 2014. Effective 1 January 2015, service members receive the Non-Article 5 Medal for service in Afghanistan for the Resolute Support mission. The medal is awarded with the "Afghanistan" clasp. The British government does not allow its personnel to accept or wear the medal, as a separate British Operational Service Medal for Afghanistan has been issued and, due to a long-standing ruling, British personnel are not allowed to wear two medals for the same campaign or operation. NATO campaign medals where a British decoration has not been issued, such as the award for Operation Unified Protector, may be worn.
