The Armed Forces Memorial at the National Memorial Arboretum in Staffordshire contains the names of members of the UK Armed Forces, Regular and Reserve, who have died on duty since 1948 (the Commonwealth War Graves Commission commemorates war dead up until 31 December 1947). In the centre is the Obelisk, which commemorates all who have died in Service, irrespective of cause or circumstance. The Memorial was dedicated in 2007 and included almost 16,000 names. Each year, the Armed Forces Memorial Naming Panel, chaired by the Defence Services Secretary, supported by senior members of each Service and a senior medical advisor, considers the names of serving Service personnel who have died during the preceding year in order to determine those who meet the necessary criteria to be included on the Memorial. A service for families is held at the National Memorial Arboretum, usually in July, to commemorate those personnel.
