Efficiency Decoration
The Efficiency Decoration, post-nominal letters TD for recipients serving in the Territorial Army of the United Kingdom or ED for those serving in the Auxiliary Military Forces, was instituted in 1930 for award to part-time officers after twenty years of service as an efficient and thoroughly capable officer. The decoration superseded the Volunteer Officers' Decoration, the Colonial Auxiliary Forces Officers' Decoration and the Territorial Decoration. In the British Commonwealth, the decoration was gradually superseded by national decorations in some member countries, in Canada by the Canadian Forces Decoration in 1951, in the Union of South Africa  by the John Chard Decoration in 1952 and in Australia by the Reserve Force Decoration in 1982. In the United Kingdom, the decoration was superseded by the Volunteer Reserves Service Medal in 1999. New Zealand continues to award the Efficiency Decoration (New Zealand) and is one of a few countries still to do so. Origin. In 1892 the Volunteer Officers' Decoration was instituted as an award for long and meritorious service by officers of the United Kingdom's Volunteer Force. In 1894, the grant of the decoration was extended to officers of volunteer forces throughout the British Empire by instituting  a separate new decoration, the Volunteer Officers' Decoration for India and the Colonies. The Volunteer Officers' Decoration for India and the Colonies was superseded in 1899 by the Colonial Auxiliary Forces Officers' Decoration. In the United Kingdom, the Volunteer Officers' Decoration was superseded by the Territorial Decoration in 1908, but it continued to be awarded in a few Crown Dependencies until 1930. Institution. The Efficiency Decoration was instituted by Royal Warrant on 23 September 1930 as a long service award for part-time officers of the Territorial Army of the United Kingdom and of the Auxiliary Military Forces of the  British Dominions, Colonies and Protectorates and India. It superseded the Volunteer Officers' Decoration, the Colonial Auxiliary Forces Officers' Decoration and the Territorial Decoration. The decoration bore a subsidiary title to denote whether the recipient qualified for its award while serving in the Territorial Army or in one of the other Auxiliary Military Forces of the Empire. The subsidiary title was inscribed on the bar-brooch of the decoration, "TERRITORIAL" in respect of the Territorial Army or the name of the applicable country in respect of other Auxiliary Military Forces. The Royal Warrant of 23 September 1930 was amended by Royal  Warrants dated 1 February 1940, 4 April 1946, 8 April 1949, 8 August 1949 and 6 August 1951. On 17 November 1952, these earlier warrants were annulled and, along with some new amendments, incorporated in one new Royal Warrant. Award criteria. The decoration could be awarded to part-time officers after twenty years of commissioned service, not necessarily continuous, as an efficient and thoroughly capable officer on the active list of the Territorial Army or of any other Auxiliary Military Force of the British Empire. Half of the time served in the ranks could be reckoned as qualifying service for  the decoration. Service in West Africa, natives of West Africa and periods spent on leave excluded, and war service was reckoned two-fold as qualifying service for the decoration. The award could also be made to any Princes or Princesses of the Blood Royal. The equivalent award for other ranks was the Efficiency Medal. Recipients serving in the Territorial Army of the United Kingdom are entitled to use the post-nominal letters TD, while recipients serving in the Auxiliary Military Forces are entitled to use the post-nominal letters ED. A recipient who had earlier been awarded any Long Service  and Good Conduct Medal or the Efficiency Medal or a clasp to either for service in the ranks, was not permitted to wear the medal or clasp together with the decoration until the full service periods prescribed for each medal or clasp and the decoration had been completed. From 1949, the required period of qualifying service was reduced to a minimum twelve years of commissioned service in the Territorial Force and the Auxiliary forces of the Commonwealth. In respect of officers whose service terminated before 3 September 1939, the qualifying period of commissioned service remained twenty years. At the same  time, a clasp was instituted which could be awarded upon the completion of each further period of six years of qualifying service. The maximum number of clasps awarded to one recipient is five. Order of wear. In the order of wear prescribed by the British Central Chancery of the Orders of Knighthood, the Efficiency Decoration takes precedence after the Ceylon Armed Services Long Service Medal and before the Territorial Efficiency Medal. Description. The decoration is an oval skeletal design and was struck in silver, with parts of the obverse in silver-gilt. The original badge is the same as that  of the King George V version of the Territorial Decoration, high and wide, but with the decoration's subsidiary title inscribed on the bar-brooch. The subsequent King George V, King George VI and Queen Elizabeth II versions are of a new design, high and wide, with a diameter ring suspender, formed of silver wire, which passes through a small ring affixed to the top back of the crown. Obverse. The obverse is an oval oak leaf wreath in silver, tied with gold, with the Royal Cypher of the reigning monarch in the centre below the Royal Crown, both in  gold. Four versions of the decoration have been awarded. Subsidiary title. The medal ribbon is suspended from a rectangular silver bar-brooch, inscribed "TERRITORIAL" in respect of the Territorial Army or with the name of the applicable country in respect of other Auxiliary Military Forces. In South Africa a bilingual subsidiary title was used, with the bar-brooch inscribed "UNION OF SOUTH AFRICA" and "UNIE VAN SUID-AFRIKA" in two lines. On the reverse the bar-brooch is impressed with silver hallmarks. Reverse. The reverse is smooth and undecorated, with the year the decoration was awarded impressed at the bottom  on decorations awarded in the United Kingdom, or with the rank, initials and surname of the recipient impressed around the perimeter in some countries. Clasps. The clasps have either the Royal Cypher of King George VI (GVIR) or Queen Elizabeth II (EIIR) in the centre, surmounted by the Royal Crown, with the year of the award impressed on the reverse. In undress uniform or when ribbon bars alone are worn, a recipient of one or more clasps would wear a silver rosette on the ribbon bar to denote each clasp. Ribbons. Three ribbons are used with the decoration, all wide . In the United Kingdom, an alternative ribbon is used when the decoration is awarded to officers of the Honourable Artillery Company, while a new regular ribbon was introduced in 1967. Discontinuation. New Zealand continues to award the Efficiency Decoration (New Zealand) and is one of a few countries to still do so. In the United Kingdom and some countries of the Commonwealth, the decoration was gradually superseded by new decorations.
