25 Engineer Regiment is one of two Air Support Engineer Regiments providing direct support to the RAF, under command of 12 (Air Support) Engineer Group. 

The Regiment provides an immediately deployable component, the Lead Air Support Squadron on rotation and each Field Squadron has a unique design and resource capability essential to the delivery of this role. 

The Regiment works closely with RAF Expeditionary Air Wings and is mainly focused on delivering six key tasks of:

• Repairing aircraft operating surfaces.
• Fuel supply.
• Explosive storage.
• Technical accommodation.
• Domestic accommodation.
• Force protection.

The Regiment also has a reserve role to deploy in support of Land Operations, which could involve engineer tasks ranging from water supply to demolitions.  

Based in Waterbeach, near Cambridge on the edge of a disused WWII airfield, which provides an excellent "back door" training area, 25 Engineer Regiment has an establishment of 511 Officers and Soldiers, formed into 3 Squadrons:

• 43 Headquarters and Support Squadron.
• 34 Field Squadron.
• 53 Field Squadron.

The Regt has now been based at Waterbeach since Aug 2007 and has deployed squadrons on operations to Iraq, Afghanistan and the South Atlantic as well as conducting major infrastructure tasks in Kenya.  Future deployments in the next operational year are likely to be world wide and in support of both Air and Land Ops. The Regiment is routinely involved in charity and construction work in the UK and it plays an active role in the local community.
