The British Army's Chemical Warfare U-Turn
A specialist British Army unit which was disbanded several years ago is being brought back to life.
Falcon Squadron, part of the Royal Tank Regiment, are experts in dealing with threats from chemical and other non-conventional weapons on the battlefield.
Five years ago the unit was stood down and their role transferred to the RAF as part of defence cuts.
But the rise of terror groups like Daesh now means chemical, biological, radiological and nuclear warfare are very real threats once again.
