The Policy on the Supplement to Military Pay, which expired on June 30, 2014, has been revised and extended through June 30, 2018. All employees who are members of the National Guard, the Armed Forces, the commissioned corps of the Public Health Service, or any other category designated by the President, and who have enlisted or have been called to active military duty in the Overseas Contingency Operations campaign (formerly the War on Terror campaign) or any successor military campaign are eligible for supplements to their military pay. Policy guidelines are available here.
