18 (UKSF) Signal Regiment

18 (UKSF) Signal Regiment is a Regiment of the Royal Corps of Signals in the British Army and provides communications and information systems support to the force elements of the United Kingdom Special Forces (UKSF). Established in 2005, the regiment is under the Operational Command of Headquarters Director Special Forces and includes signal squadrons from both the Royal Corps of Signals and the Royal Marines.

The regiment's tasks are to provide signals intelligence, electronic intelligence, maintaining communications and their security during special forces missions. Operators may be required to accompany UKSF on operations and need to be HALO and firearms trained to special forces levels. They are also required to be trained in various special forces techniques such as resistance to interrogation and escape and evasion. The 18 (UKSF) Signal Regiment run their own special forces selection programme called the Special Forces Communicator (SFC) course.

History
The Ministry of Defence does not comment on special forces matters, therefore little verifiable information exists in the public domain.

 * SBS Signal Squadron
