I may be showing my ignorance here but I have not heard MFV's described before as dual role. Please could someone explain? Many thanks.

Generally when an ARFF vehicle is described as being "duel role" it means that the vehicle can also be used for structural protection for hangers, terminals, etc. It's pump can be controlled from outside the cab in a fashion like the pump controls on a domestic pump. The term "dual role" has been used for many years when talking about ARFF vehicles that can help fight structure fires as well as crash fires.

Further to Johns comments. "Dual Purpose or DP " was the term used within the RAF up until recently. Crash lines used to consist of a rescue unit, major foam producers and "DPs". When a fire occurred on a domestic site, a DP would be despatched, the crew dealing with the fire until the arrival of a Local Authority attendance. The role of the DP was that of bulk water carrier to replenish major foam producers. However, they all carried decent amounts of foam compound to act as Fts in their own right. There were three kinds of DP Mk 1 carried no roof monitor and was twin axle. The DP 2 and 3 carried roof monitors equipped with 20x branches producing aspirated foam ( all RAF major foam trucks produced air blown foam up until the Mk9 ) The DP series were all Thorneycrofts with RR B81 petrol engines. The standard engine in all major airfield appliances for many years.

If anyone has the Vintage Fireground series on DvD or video on VF 1 you can see film footage of the Thornycroft DP1 being built, also on VF3 there is also film footage of a Thornycroft DP1 arriving at a fire during the fireman's strike of 1977. THis one is green with orange stripes added.
