Established on April 10, 1981, the Army Overseas Service Ribbon is awarded to members of the United States Army or Army Reserve who carry out a qualifying tour overseas. It may be granted retroactively to individuals who served in a standard overseas tour prior to August 1, 1981 as long as those they maintained active status on or after that date.
The ribbon features a thick dark red stripe in the center, flanked by a thin vertical yellow stripe on either side and a stripe of light blue and dark blue proceeding outward.
Subsequent awards may be indicated by numeral devices and Overseas Service Bars for individuals who served in eligible overseas combat zones.
