The Volunteer Reserve Decoration (VD until 1947, then VRD) was awarded to commissioned officers in the United Kingdom's Royal Naval Volunteer Reserve (RNVR) for long service and good conduct. The VRD was established in 1908. The medal has an oval medallion, consisting of the cypher of the reigning monarch in silver gilt surrounded by a silver rope tied with a reef knot at the base and surmounted by a gilt crown which acts as the ribbon suspension, hung from a ribbon which was dark green until 1919 and navy blue with a narrow central bands red-green-red thereafter. Originally, 20 years service was required, with wartime service counting double, and service in the ranks counting half.
