21 Engineer Regiment
Based in Ripon, North Yorkshire, 21 Engineer Regiment is part of 4 Mechanized Brigade based around Catterick Garrison.
The Regiment consists of the following sub units all of which have their own ethos and traditions:
• 7 Headquarters and Support Squadron
• 1 Field Squadron
• 4 Field Squadron
• 103 Field Squadron
• 106 Field 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).
Now that the Regiment is part of the Army 2020 Adaptable Force it has taken under command two Army Reserve sub units: 103 Field Squadron (located in Newcastle) and 106 Field Squadron (located in Sheffield).
