The Territorial Decoration (TD) was a medal of the United Kingdom awarded for long service in the Territorial Force and its successor, the Territorial Army. This award superseded the Volunteer Officer`s Decoration when the Territorial Force was formed on 1st April 1908, following the enactment of the Territorial and Reserve Forces Act 1907, (7 Edw.7, c.9) which was a large reorganisation of the old Volunteer Army and the remaining units o militia and Yeomanry. However, the Militia were transferred to the Special Reserve rather than becoming part of the Territorial Force. A recipient of this award is entitled to the letters “TD” after their name (post-nominal).
The criterion was for a minimum of 20 years service in the Territorial Force and Territorial Army, with war service counting double and service in the ranks counting half. In 1930 the new Efficiency Decoration was introduced to be awarded to all three services, but when the ED was awarded to a Territorial Army officer it continued to be known as the Territorial Decoration and the recipient still used the letters TD after their name. It was finally replaced by the Volunteer Reserves Service Medal, awarded to all ranks in all services, in 1999.
