The Regiment consists of the following sub units all of which have their own ethos and traditions:
• 7 Headquarters and Support Squadron
• 1 Armoured Engineer Squadron
• 4 Armoured Engineer Squadron
• 73 Armoured Engineer Squadron
• Royal Electrical and Mechanical Engineers Light Aid Detachment
Each Engineer Squadron provides close support to the units within 4 Mechanized Brigade, allowing them to live, move and fight within their area of operations. More specialised capabilities are also held in the Headquarters and Support Squadron, such as a Reconnaissance Troop, Construction Design Cell, Divers, plant vehicles, and Automotive Bridge Launching Equipment (ABLE) for General Support Bridging (GSB).
However, as the Regiment re-roles to become part of the Army 2020 Adaptable Force in April 2104, 1 and 4 Armoured Engineer Squadrons will become Field Squadrons and 73 Armoured Engineer Squadron will disband. At this time, the Regiment will also take under command two Army Reserve sub units: 103 Field Squadron (located in Newcastle) and 106 Field Squadron (located in Sheffield).
