Established on July 9, 1918, the Spanish War Service Medal was originally created to recognize United States Armed Forces personnel, such as National Guardsmen, who contributed to homeland defense efforts in the Spanish-American War but were not eligible for the Spanish Campaign Medal.
Qualifying individuals include those who carried out active duty between April 20, 1898 and April 11, 1899 for a term of no less than 90 days.
The medal features a sword in its sheath suspended from a table that reads “FOR SERVICE IN THE SPANISH WAR”; the image is encircled by a wreath of laurels. The reverse of the medal features an image of the United States Coat of Arms over a scroll that reads “FOR SERVICE.” The ribbon is green with a yellow stripe toward each edge.
