Selection and Training in the British Army Selection and training in the British Army is the process by which candidates for service are identified , inducted and brought onto the trained strength . The process is the responsibility of the Adjutant General , the personnel director for the Army based at Trenchard Lines in Wiltshire . Selection . Candidates for all three of the British Armed Forces are first handled through Armed Forces Career Offices which are located in major conurbations around the United Kingdom supporting the respective recruitment functions . The selection process involves a number of suitability interviews , an aptitude test to identify training potential , medical and fitness assessments and a residential selection board . For potential soldiers this will include an opportunity to select a Regiment or Corps , as well as a trade to join . Later training is oriented around this choice . Officer candidates will , during the selection process , become sponsored by a Regiment or Corps to undertake training . This sponsor does not undertake to accept the candidate on completion of officer training . Regular Army . Training . Candidates for the Army undergo common training to bring all personnel to a similar standard in basic military skills , further specialist training is delivered subject to the Regiment or Corps that the individual has been identified as a candidate for . Completion of Phase 2 training brings the individual onto the trained strength however each of the British Armed Forces will continue to deliver specialist and generalist training throughout the individual career . Much training in the British Armed Forces has been accredited by various awarding bodies , resulting in the opportunity to gain civilian qualifications through service training activities . The structure of training is different for soldiers and officers : Soldier Training . There are two phases in the training for recruits into the regular army , phase 1 encompasses the Common Military Syllabus ( Recruits ) ( CMSR ) and phase 2 delivered by specialisation . CMSR covers the skills needed to survive and operate in a field environment , fitness and seeks to imbue the ethos and principles of the British Army . The trainee is required to demonstrate competence in thirteen training objectives over the fourteen week course . Phase 1 . The initial phase features the basic training for all new recruits . Prospective soldiers attend either one of five training establishments : Phase 1 training is intended to bring all soldiers to a base level of military competency , capable of operating in the field , force protection , operational security and displaying the other characteristics of a member of the British Army . The training embeds the core values : Phase 2 . The second phase involves the new officer or soldier training for branch of the service they wish to specialise in , and then undergoing the specific training . This is with one of the specialist schools located around the country : Infantry Training Centre . As of 2001 , infantry training is undertaken as a single 26 week course ( 28 weeks for the parachute regiment , or any of the five guards regiments ) at the Infantry Training Centre at Catterick Garrison , as opposed to being divided into Phase 1 and Phase 2 training . The ITC is divided into four separate battalions ; these are divided into companies , each of which are responsible for one of the infantry ' s administrative divisions : Officer Training . There is also a shorter course for Professionally Qualified Officers ( those holding qualifications in Medicine and medical - related fields , Law or Clergy ) that provide basic military training and lasts for ten weeks . These candidates are usually commissioned as Captain s . The Late Entry Officers Course is for serving soldiers who are chosen for officer training and lasts for four weeks for Regulars and two weeks for TA . Territorial Army . Soldiers . For TA soldiers , recruit training is structured into two phases : Phase 1 , also known as the Common Military Syllabus ( Recruit ) ( CMS ( R ) ) Course , and Phase 2 , specialist training . Phase 1 In Phase 1 , recruits cover the Trained Soldier Course ( TSC ) part A ( this replaced CMS ( R ) in 2009 ) in a series of 6 training weekends at Army Training Units , formally known as Regional Training Centre s ( RTCs ) . At some ATUs the TSC ( A ) is also run as a 2 week consolidated course . For non - infantry units , TSC concludes with a two week training course ( TSC Part B ) normally held at an Army Training Regiment , whilst infantry recruits have an extra 3 weekends and then go directly to their Phase 2 Training at Catterick . Recruits to the 4th Battalion , The Parachute Regiment and the Honourable Artillery Company complete their equivalent of CMS ( R ) within their own units . Phase 2 Phase 1 is followed by Phase 2 , a further period of specialist training specific to the type of unit the recruit is joining . This is normally conducted by the Arm or Service that the recruit is joining , for example for infantry units , Phase 2 consists of the two week Combat Infantryman ' s Course ( TA ) ( CIC ( TA ) ) held at the Infantry Training Centre , Catterick . Officers . To gain a commission , Potential Officers have to pass through four modules of training , which together form the Territorial Army Commissioning Course ( TACC ) . Module 1 is the same as the Common Military Syllabus ( Recruit ) course . As many Officers initially serve a period of time as Soldiers , this module is only undertaken by the minority that join the TA directly as Potential Officers under the Direct Entry TA Potential Officer ( DETAPO ) system . Module 2 covers training in Tactics , Leadership , Doctrine and Navigation , both in theory and in practice , and a further series of selection and aptitude tests are undertaken , usually spread over 10 weekends . This also includes passing The Army Officer Selection Board Briefing and Main Board , after which Potential Officers are formally designated as Officer Cadet s . Module 3 applies the theory taught in Module 2 into a 9 day Battle Camp . Modules 1 to 3 are run by Regional Training Centre s around the UK . Module 4 . Passing the AOSB and Module 3 then enables Officer Cadets to attend an intensive three week Assessment at the Royal Military Academy Sandhurst , which forms Module 4 . On successful completion of Module 4 , the Officer Cadets receive their Commission and become Second Lieutenant s . Further training that is required prior to them being considered for operational deployment and promotion to Lieutenant includes : Post Commissioning Training ( formerly known as Module 5 ) , again run at an RTC , over 3 weekends . Special To Arm training is specific to the type of unit the Subaltern is joining , for example , the 2 week Platoon Commander ' s Battle Course held at the Infantry Battle School in Brecon .
