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. It was screened on BBC One on 20 and 21 November 1999. The serial 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 serial was released on VHS on 29 November 1999. On 7 January 2004 the serial was issued on DVD in the Netherlands.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. Music for the serial was written by Debbie Wiseman. When it aired in the United States, the serial was re-titled Peacekeepers.
