Criteria: Designed by the U.S. Mint and is awarded to members of the U.S. Navy and Naval Reserve who qualify as Expert with a rifle on a prescribed military rifle course.
The medallion is a bronze disc bordered with a rope edge. The ribbon hangs from a smaller disc superimposed at the top containing the figure of an eagle clutching an anchor in its talons, taken from the seal of the U.S. Navy. The larger disc has a raised "bull's eye" (rifle target) in the center. Above the bull's eye is the raised inscription, "EXPERT RIFLEMAN" and on the lower edge, the curved inscription, "UNITED STATES NAVY."
The ribbon is navy blue with three thin light green stripes. Although originally intended as a single, one class award, the concept was extended during the Vietnam War to provide for two additional levels of achievement with the creation of the Navy Rifle Marksmanship Ribbon..
