History:
From 1930 recipients in Britain were allowed to continue using the letters TD after their names, but in the Commonwealth the letters ED were used instead. The 20 years qualification was reduced to 12 years in 1949 , bars for each additional 6 years being added. In 1969 the British bar was changed to T & AVR , on the establishment of the Territorial and Army Volunteer Reserve, the ribbon being then altered to half green, half blue, with a central yellow stripe. In 1982 the title of Territorial Army was resumed, so the inscription on the bar reverted to TERRITORIAL but the blue, yellow and green ribbon was retained.

Observe:
An oval sketital medal in silver and silver-gilt with the crowned monogram in an oak wreath, the ring for suspension being fitted to the top of the crown. It differs from previous decorations in having a suspender bar denoting the area of service : Territorial (UK) , India, Canada, Fiji or other overseas country inscribed as appropriate - the previous ribbon was retained.
