To mark the 50th anniversary of the start of Operation Banner in Northern Ireland, commemorations were held on Wednesday at the Arboretum in Staffordshire. Op Banner lasted almost 38 years between 14 August 1969 and 31 Jul 2007 - more than 300,000 members of the UK Armed Forces were deployed in this time. Some 1,441 serving personnel died on deployment or in related paramilitary acts.
