The records are those in series WO 420 and relate to the Corps of Royal Electrical and Mechanical Engineers regiment (REME).
Professional military researcher Simon Fowler told Family Tree: ’This is a most welcome surprise, although it will be a few years yet before all MOD’s service records are available in this way. REME was formed in 1942. With minor exceptions, the Corps is responsible for the examination, modification, repair and recovery of all mechanical, electronic, electrical and optical equipment of the Army beyond the capacity of unit non-technical personnel. They are a key component of an increasingly mechanised army.’
