Summary: Army Instructional film describing the work of the Royal Electrical and Mechanical Engineers (REME) in the field. The film examines a REME unit attached to an armoured division, and shows the types of work undertaken, including the recovery of damaged or broken down vehicles, such as Centurion tanks, the repair of vehicles where possible and their despatch to base facilities when repairs are beyond the capabilities of the field unit. The facilities available in a field workshop are described, including the repair of radios, instruments and small arms, the fabrication of spare parts, and the stores organisation. The mobility of the unit is demonstrated as it follows the advancing combat units, relocating to a new site when necessary.
