TO KEEP THE PEACE: THE INTERNAL SECURITY ROLE [Main Title]
Dramatised Army Instructional film in which a newspaper reporter spends several hours with a British Army battalion deployed in an unnamed Northern Irish city. A Lieutenant-Colonel explains the basic principles under which the Army provides assistance to the civil authorities, outlines the nature of the working relationship between the Army and the civilian police and discusses sources of information regarding terrorist activity. Various scenes are used to illustrate this discussion, including the discovery of a suspect car, which subsequently explodes, vehicle checkpoints, night patrolling and the establishment of good relationships with the public. The reporter joins an Army unit as it stands by to assist the police in dealing with a potentially violent protest march; when the police are unable to cope the Army gives assistance and disperses the protest. A cordon and search operation is then mounted on a factory believed to be used by terrorists; the searchers react to sniper fire, arrest suspects and discover a cache of terrorist weapons.
