Royal Electrical and Mechanical Engineers
The REME Corps was formed on the 1st October 1942. Their role was and still is to maintain and repair the Army’s equipment. They quickly proved themselves highly capable during the battles of El Alamein.
At the time of this photo, REME was involved in implementing the first phase of the military’s reorganisation. The aim was to gradually replace the many different corps involved in maintenance with this newly formed corps. Tradesmen from the Royal Army Ordnance Corps (RAOC), Royal Army Service Corps (RASC), and the Royal Engineers (RE) were transferred to REME. Facilities to train new recruits were also created.
