254 (SGIS) Sig Sqn - Specialist in Army Information Services - Key Facts

Unit footprint, command and control

254 (SGIS) Signal Squadron is a National Army Reserve unit which recruits from across the UK.  While it is administered by the Royal Signals Central Volunteer Headquarters (CVHQ) in Corsham, command, control and co-ordination is largely exercised by the effective use of IT, given that the unit membership is dispersed throughout the country and opportunities for collective training and development are relatively few in number.  The Headquarters and other elements of 15th Signal Regiment is located in Blandford Camp and all unit tasks are undertaken with the authority of the Regimental Operations Team.  In order to meet its wide range of routine and operational commitments, the remainder of the Regiment is located in Corsham, Bicester and overseas.

Training, development and capability delivery

The Squadron typically assembles six or seven times each year for military training, unit development, educational and multi-stream capability delivery purposes.  In addition, it undertakes a multitude of tasks for a range of customers, from as little as a day in duration to many months.  All individuals are required to pass Military Annual Training Tests, be proficient in Basic Close Combat Skills, develop an awareness of the wider Army and its Land environment client base, gain an understanding of Corps and Army culture and be able to work in small teams to deliver capability to our clients.  All individuals must complete a minimum of 19 days training per year, which should include time spent delivering task-based capability.

Vacancies for candidates of many types

We currently have vacancies for specialist, Professionally Qualified Officers (PQOs), mainstream officers, Warrant Officers (WOs) and Non-Commissioned Officers (NCOs).  We recruit specialists directly from the commercial IT industry, but also many ex-Regulars and those already serving in the Reserves who have the right skills.  The unit rank range is Lance Corporal to WO1, then Captain to Lieutenant Colonel.  All candidates of whatever background and experience must attend a unit Selection Board.  Potential PQOs must also then pass an Army Officer Selection Board before joining the unit in the rank of Captain, followed by a Commissioning Course at the Royal Military Academy Sandhurst.

Enlistment requirements and constraints

Specialist Officers (PQOs) must be aged between 27 and 50 upon commissioning.  Ex-Regular and currently serving Reserve Officers can be up to 57 years of age upon joining the unit, WOs and NCOs up to 43.  Potential PQOs must have been resident in the UK for at least 5 years upon selection and be both agreeable to and capable of Developed Vetting.

254 (SGIS) Sig Sqn - What We Do

As an outcome of the UK Strategic Defence and Security Review (SDSR) of 2010, the Future Reserves 2020 (FR20) consultation paper Delivering the Nation’s Security Together published in late 2012 explained how the Army Reserve needed to almost double in size to a trained strength of 30,000.  Particular emphasis was placed upon the requirement for many more specialists, i.e. reservists who are recruited primarily for their professional expertise and skills which are in short supply in the Regular Army.  As a specialist Army Reserve unit, 254 (SGIS) Sig Sqn therefore needs to greatly increase its strength and is now recruiting at a higher rate than ever.

Information enables the Army and Defence as a whole to succeed in the modern age.  Immense reliance is placed upon information systems and technology to equip, train and deploy our Armed Forces.  Data is as important to the military as personnel, supplies and weaponry, so the subject of how information is managed and exploited is a critical one.  254 (SGIS) Signal Squadron provides consultancy-style expertise in relation to both Information Management (IM) and Information Exploitation (IX), in order to guarantee the outcome known as ‘information superiority’.

Since its formation in 2008 in its previous guise as the Land Information and Communication Services Group (LICSG), 254 (SGIS) Signal Squadron has undertaken tasks for clients such as Defence Equipment & Support, the Permanent Joint Headquarters in Northwood and Army Headquarters in Andover, in numerous locations in the UK, in Germany and in places much further afield such as the Falkland Islands, Kenya and Afghanistan.  Individuals have also supported tasks carried out by the Land Information Assurance Group (LIAG) and the Squadron is now very much busier than ever.
