Warriors is a British television drama serial, written by Leigh Jackson, produced by Nigel Stafford-Clark and directed by Peter Kosminsky. It starred Matthew Macfadyen, Damian Lewis and Ioan Gruffudd. The music was written by Debbie Wiseman. It was screened on BBC One. The series tells the story of a group of British peacekeepers serving in a peacekeeping operation of the UNPROFOR in Vitez, in Bosnia during the Lašva Valley ethnic cleansing in 1993. The film emphasises the contradictions of the mandate of the peacekeepers, and the psychological trauma that they sustain while being forced to observe atrocities perpetrated against civilians without being able to intervene, and being subject to deliberate provocations against which they are unable to retaliate. The ironic title of the programme is taken from the name of the armoured vehicle used by the British forces, the FV 510 Warrior. When it was released in the United States, the film was re-titled Peacekeepers.
