When we was in Ireland, I used to listen to the news and I thought - Christ, I hope I never go out to Lebanon (CORPORAL KEITH DICKEN, Beirut) Most of Lebanon is occupied by Israeli, Syrian and Palestinian forces. But in Beirut itself, 100 British soldiers are serving with the multinational peacekeeping force. Their task is to help the Lebanese Government end eight years of violence which reached a climax last, summer with the massacre at Sabra and Chatila refugee camps. Last Saturday's, Q.E.D.- Before the Massacre looked at British volunteer medical staff. Tonight's programme follows the British soldiers on and off duty and explores their reactions to what they have seen and learned about the people they hope to protect.
