Members of 12 Brigade Reconnaissance Force were supporting Afghan soldiers in an operation which also yielded a large number of pressure plates and other bomb making components.
The Light Dragoons make up much of the Force along with 12 other British units.
As part of an Afghan-led operation intelligence reports prompted a swoop on a Nahj-e-Saraj Mosque being used as an IED bomb making factory.
According to Task Force Helmand the raid caught the insurgents off guard with freshly made tea and flip flops left behind as they fled.
Explosives and detonators were destroyed at the site while some ready made devices were taken to Camp Bastion for analysis.
