a. Authorization. SECNAV letter 1650 Ser NDBDM/886
17 September 1986.
b. Navy and Marine Corps Overseas Service Ribbon Eligibility Requirements. Awarded to officers and
enlisted personnel of the United States Navy, Navy Reserve,
Marine Corps, and Marine Corps Reserve. Each service has distinct criteria that delineate eligibility; Navy personnel
assigned to Marine Corps units follow Marine Corps policy, and
(1) Active Duty Personnel: 12 months of consecutive or
accumulated duty at an overseas shore based duty station.
(2) Reserve Personnel: 30 consecutive days or 45
cumulative days of service at overseas duty stations, including
deployed units and units homeported overseas, regardless of the
type of orders the member is serving under. For eligibility
purposes, two Inactive Duty for Training (IDT) periods equal one
day of qualifying service. Travel time does not count.
(a) Navy Reserve Personnel
1. Effective 11 September 2001, Navy Reservists
may earn their initial award of the Overseas Service Ribbon
(OSR) under the Reserve service requirements, but must fulfill
the active duty service requirements for any subsequent award.
See paragraph (b) below regarding service with the Marine Corps
2. For overseas domiciled Reservists,
qualifying service must be completed in a billet with an
established Navy Reserve Unit.
(b) Personnel Serving with the Marine Corps Reserve.
Since personnel serving with the Marine Corps operating forces,
active or reserve, are not eligible for this award, Marine Corps
personnel or Navy personnel serving with the Marine Corps
operating forces, mobilized in support of a specific operation
or contingency are also not eligible for the Navy and Marine Corps Overseas Service Ribbon (OSR).
(3) Overseas is defined as duty outside the United
States at shore based commands. Mainland Alaska and Hawaii are
not eligible duty stations; however, service in Adak, Alaska,
does qualify. For active duty personnel, duty on board CONUS-
based, deploying ships, squadrons, units, or with the Marine
Corps operating forces does not qualify.
(4) Restrictions and Waivers
(a) An individual may not receive the Sea Service
Deployment Ribbon and the OSR for the same period if assigned to a Marine Corps unit. After 1 October 1999, personnel assigned
to overseas Navy commands may receive both awards if all
eligibility requirements are met. However, the same period of
time cannot be used to earn eligibility for both the Naval
Reserve Sea Service Ribbon and the Navy and Marine Corps Overseas Service Ribbon (OSR).
(b) For active duty personnel, not more than 14 days
of service time may be waived. There is no waiver for inactive
reservists. For posthumous awards, the time requirements may be
waived by CNO/CMC, on a case-by-case basis.
(c) Personnel serving with the Marine Corps
operating forces, active or reserve, are not eligible for the Navy and Marine Corps Overseas Service Ribbon
c. Initial and Subsequent Awards. Qualifying service
performed between 15 August 1974 and 1 January 1979 will be
