The Unit
Every other UK Special Forces unit in this register is built around the man with a rifle. 63 (UKSF) Signal Squadron is the odd one out — and the indispensable one. It is the reserve signals squadron of UK Special Forces, part of the 18 (UKSF) Signal Regiment, and its people are Special Forces Communicators: the operators who carry the radios, run the CIS and keep the SAS, SBS and wider UKSF talking on operations.
That makes it genuinely unusual — a tier-one reserve unit whose entry prizes brains and technical aptitude as much as a backpack and a bergen. Modern special operations live or die on communications, electronic warfare and data; 63 is the reserve element that provides them.
The Gate
63 is open to both men and women — serving personnel and, notably, civilians — who are "robust, intelligent and possess the physical stamina to operate in demanding and hostile environments." Those with previous communications or IT experience have a markedly better chance of being accepted: this is a unit that needs technicians who can also soldier.
The mix is the point — the squadron wants the rare person who is both a serious comms specialist and physically capable of keeping pace with assaulters.
Selection
The path is its own animal — part Selection, part trade course.
Assessment Course
An Assessment Course over three weekends, then a two-week Royal Signals communications training course, to be judged fit for appointment.
SF Communicators Course
The core qualification runs six phases: technical trade assessment; general support communications; physical aptitude; close support communications; conduct after capture (resistance to interrogation); and military training including special-forces parachute training.
Probationary year
Newly badged communicators serve a probationary year, completing mandatory courses and a two-week exercise to reach mobilisation fitness.
The Standards
Indicative of the Selection tier this reference uses — with a technical twist no other UKSF unit shares:
Train To The Standard
63 rewards the technician who can also ruck and march. The Gate's Selection tier maps the run, ruck and strength base it's built on.
