The Army Service Ribbon is awarded to members of the Army, Army Reserve, and Army National Guard for successful completion of initial-entry training, which for officers is considered to be successful completion of their basic/orientation or higher level course. Enlisted soldiers will be awarded the ribbon upon successful completion of their initial MOS producing course.
For those service members who completed initial entry training prior to 1981, the Army Service Ribbon is retroactively awarded, provided the service member was still on active duty after 1981. For those service members who enlist in the Army after serving with another service (and who may not be required to complete initial entry training) the Army Service Ribbon is awarded after four months of active service.
The Army Service Ribbon is presented as a one-time award only since it is not possible to earn it more than once.
