The Royal Signals trades are the employment specialisations of the Royal Corps of Signals in the British Army. Every soldier in the Corps is trained both as a field soldier and a tradesman. There are currently six different trades, all of which is open to both men and women:

 Cyber Networks Engineer: an expert in computer network deployment and operation, and military radio communications.
 Cyber Information Systems Engineer: an expert in data communications and computer networks, web and database development and cyber security.
 Power Engineer: an expert in designing, maintaining and repairing deployable power systems.
 Cyber Infrastructure Engineer: an expert in designing, installing and repairing fibre optic and copper voice and data networks, both internally and externally.
 Electronic Warfare & Signals Intelligence Operator: an expert in both tactical electro-magnetic, cyber and signals intelligence on the battlefield and close tactical support to and advice to bomb disposal units.
 Supply Chain Operative: an expert trained in all aspects of communications logistics and supply, including transport, warehouse management and administration.

Initial training common to all trades
Every soldier first completes Basic Training, also known as Phase One Training. Adult Entry soldiers complete a 14-week course at Army Training Regiment at Winchester or at the Army Training Centre Pirbright, in Surrey. Junior Entry soldiers (16-17.5 years old) complete a 23-week course at the Army Foundation College at Harrogate. Both Junior and Adult Entry course teach the common basic military skills such as foot drill, weapons handling (Skill at Arms), how to live and work outdoors (fieldcraft), navigation, leadership, first aid and how to tackle an assault course.  In addition they develop their stamina and fitness.

On completing his or her initial training every soldier then moves to 11th Signal Regiment at Blandford Camp in Dorset to commence their trade training.

Supervisory trades

Staff Sergeants and Warrant Officers work in one of five supervisory rosters:
Yeoman of Signals (YofS)
Yeoman of Signals (Electronic Warfare) (YofS(EW))
Foreman of Signals (FofS)
Foreman of Signals (Information Systems) (FofS(IS))
Regimental Duty

Candidates for YofS and FofS are selected from the Cyber Engineer trades and during training have the opportunity to complete Bachelors and Masters degrees . Both are obtained through the Royal School of Signals Blandford whilst being validated by Bournemouth University.

Subsequent employment
After basic and trade training most Royal Signals tradesmen are posted to the Field Army as Class 3 trained soldiers in the rank of Signaller. Electronic Warfare & Signals Intelligence Operators however, leave training as Lance Corporals. Cyber Information Services Engineer will leave Phase 2 as Signallers, but on completion of continuation training and Class 2 certification, will have accelerated promotion to Lance Corporal. After a year's experience all tradesmen become eligible for upgrading to Class 2 and a pay rise.  Throughout their careers tradesmen attend further training courses (including upgrading to Class 1).  Promotion is based on experience, ability and merit.  Depending on their trade, upon reaching the rank of Sergeant, soldiers may apply to join one of the supervisory rosters, which brings extra responsibility and qualifications.  Alternatively, soldiers from any trade may choose to follow a career path at Regimental Duty, in which they specialise in delivering military training and, if successful, fill roles such as Squadron Sergeant Major (SSM), Regimental Quartermaster Sergeant (RQMS) and Regimental Sergeant Major (RSM).

Soldiers from any trade can volunteer for service with 216 Parachute Signal Squadron, completing 'P' Company parachute training, as a Special Communicator with 299 Signal Squadron (Special Communications) or as a Special Forces Communicator with 18 (UKSF) Signal Regiment. A small number may undertake the All Arms Commando Course for service with 3 Commando Brigade.

Signallers of all trades could previously apply to join the Royal Signals Motorcycle Display Team, better known as the White Helmets, however the White Helmets were disbanded at the end of 2017.

Commissioning

Signallers may apply for commissioning, either as a Direct Entry officer undertaking the complete training package at Royal Military Academy Sandhurst, or as a Late Entry officer, undertaking a short commissioning course at Sandhurst.  LE Officers are employed as Traffic Officers, Technical Officer (Telecommunications) or General Duties based on experience as a Yeoman of Signals, Foreman of Signals or Regimental Duty.
