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 assault is the loud part. The reason it works is a reservist on a hillside who can reach a satellite, a drone and headquarters at once — and keep doing it when everything else has failed."

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.

Phase 01

Assessment Course

An Assessment Course over three weekends, then a two-week Royal Signals communications training course, to be judged fit for appointment.

Phase 02

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.

Phase 03

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:

Technical trade · comms / CIS / IT
the differentiator
Physical aptitude · loaded marches
keep up with assaulters
Aerobic base · run / endurance
well above conventional
Conduct after capture · SERE
a UKSF gate
SF parachuting
insertion skill

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.
