British Special Forces at work in Afghanistan
US Army General Dan McNeill, the commander of Nato forces in Afghanistan, said that the discovery of more than 50 roadside bombs and timers in lorries crossing the border from Iran last month proves that Iran's Quds Revolutionary Guards are actively supporting the Taliban.
British special forces, believed to be from the Special Boat Service, played a prominent role in tracking and intercepting two lorries that crossed from Iran into Afghanistan's Farah Province on Sept 5.
They discovered EFPs, which "do not get manufactured with scavenged parts. They have to be manufactured specifically for the task, and manufactured with some precision. That requires tool and dye works, a forge, raw materials, and some expert knowledge in both design and manufacture. It isn't something the Taliban can produce. . ."
The Special Boat Service (SBS) is the special forces unit of the British Royal Navy. It might appear to be a little far from water here; however it also provides support to customs police, reconnaissance in the deep battlespace, and assault on verified targets (Wiki).
