A Sea Service Ribbon is an award of the United States Navy, U.S. Marine Corps, U.S. Coast Guard, the U.S. Army, and the NOAA Commissioned Officer Corps which recognizes those service members who have performed military duty while stationed on a United States Navy, Coast Guard, Army, or NOAA vessel at sea and/or members of the Navy, Marine Corps or Coast Guard who have been forward-deployed with their home unit.
[2] Duty aboard U.S. Navy, U.S. Coast Guard, U.S. Navy Military Sealift Command, NOAA vessels, or aboard Army leased or foreign and non–military vessels may also qualify if soldiers serving on those vessels have a formally assigned primary mission that is accomplished underway, are in an active status, and are approved for creditable sea service by the Career Sea Pay Office.
The Chief of the Marine Qualification Division is the approval authority for award of the ASDR to eligible service members.
The ASDR may be awarded retroactively to those personnel who were credited with qualifying service, as defined in regulations, after August 1, 1952.
[3] Subsequent awards are authorized upon completion of an additional two years of cumulative sea duty under qualifying conditions.
[2] The U.S. Army Sea Duty Ribbon is 1+3⁄8 in (35 mm) wide, composed of vertical stripes.
The Sea Service Deployment Ribbon is granted to any member of the U.S. Navy or U.S. Marine Corps assigned to a deployable unit (e.g., a ship (including submarines), aircraft squadron, air wing or air group, detachment, battalion, Marine Expeditionary Unit, Marine Air Ground Task Force, or other unit type that operates away from its assigned homeport) and is forward-deployed for a period of either 90 consecutive days or two periods of at least 80 days each within a given 12-month period; or 6 months stationed overseas in a forward deployed location.
Active-Duty members assigned to a deployable Navy Reserve unit are also eligible for the award under the same qualifying service requirements.
Additional restrictions apply to Inactive Duty Training (IDT) drill periods and travel days.
