The Silver Star stands as the United States' third highest award for combat valor. Established on July 16, 1932, the Silver Star actually traces its history back to the Silver Citation Star, established on July 9, 1918. The Citation Star was a silver star device which was attached to the service ribbon of the campaign medal for which the individual was cited in Official Orders for Gallantry in Action.
Most Citation Stars are found on World War I Victory Medals. To convert their Citation Stars to Silver Star medals, service members were required to present copies of the official orders which made them eligible for the Citation Star.
While the degree of heroism required to earn the Silver Star is less than that required for the Medal of Honor or Distinguished Service Medal, it must nevertheless have been performed with marked distinction.
