39 Engineer Regiment provides Force Support engineering to both the Royal Air Force (RAF) and to the Army; as such it is the only regular Regiment focused on providing force support to the Air component. The LASS is equipped to offer specialist Air Support Engineering as well as a composite of Combat Engineer and Artisan trade skills making it a versatile, flexible and highly employable Force Support asset. It is particularly 'construction centric' and there is a Construction Supervision Cell (CSC) within each of the Field Squadrons. Consequently it is regularly called upon to support UK operational commitments.
The Regimental ORBAT currently includes:
34 Field Squadron
48 Field Squadron
53 Field Squadron
60 Headquarters and Support Squadron
65 Field Support Squadron
