Active Duty - United States

United States

In the United States military, active duty refers to military members who are currently serving full-time in their military capacity. Members of a reserve component are not generally considered active duty. However, in support of the Global War on Terror and other contingency operations, a large number of Reservists in all branches have been called to active duty in an operational capacity. Many will argue that today's Reserve forces are no longer the "strategic" Reserve of the Cold War. Those Reservists deployed in support of contingency operations, either as a unit or by individual augmentation, are also considered active duty. These terms may also be applied to military forces of other nations, although the details concerning obligations to serve may differ.
