One of Britain's biggest exercises to train troops and emergency services to deal with a chemical attack was held on Saturday.
The exercise was one of the largest in Britain
Nearly 900 soldiers, police officers, firefighters and paramedics took part in the simulated incident at Dalton Barracks, near Abingdon, Oxfordshire.
The Territorial Army troops involved - from the Thames Valley and Hampshire - were part of
the new Civil Contingencies Reaction Force (CCRF).
Set up after the 11 September attacks, the force is designated to come under police command in the event of natural disasters, accidents or terrorist attacks.
The exercise saw those troops establishing a centre to cope with a large-scale evacuation after a "major chemical incident".
Meanwhile, fire and rescue services from Oxfordshire, Buckinghamshire and
Berkshire sealed off the area and began the mock decontamination of people.
They worked closely with police, the ambulance service and local council
representatives in the exercise, codenamed Autumn Roebuck 2.
About 400 soldiers and cadets acted as civilians while 200 soldiers, 150
firefighters with 30 appliances and 60 police officers took part.
Mr Searle was pleased with how the exercise went
Captain Marcus Dicks, of the Royal Rifles Volunteers, said: "We have to remember we would be dealing with civilians here, not
"They would be shocked, tired, hungry and cold and it would be up to us to
look after them at the same time as processing them through the centre."
Richard Searle, emergency planning officer at Thames Valley Police, said: "It
has gone well today considering it is the first time we have worked together
with the CCRF."
The exercise comes after a simulated terrorist attack on the Tube was held in London in September.
