Basic training
They are known as Full-Time National Servicemen (NSFs).
Based on their Physical Employment Status (PES) grade determined by a pre-enlistment medical examination, NSFs may undergo either a standard, enhanced, modified, or obese BMT programme at the Basic Military Training Centre on the offshore island of Pulau Tekong or at the various military units that directly accept mono-intake PES A and B recruits. A similar 4-week BMT is conducted at Kranji School 5 for enlistees deemed unfit for combat roles. 
Throughout their BMT, NSFs will acquire the basic soldiering skills by learning how to execute drills, undergoing physical training activities aimed at developing physical fitness and preparing them for the Individual Physical Proficiency Test (IPPT), learning how to handle the SAR 21 assault rifle and SFG 87 hand grenade, completing a Standard Obstacle Course and Battle Inoculation Course, and completing a five-day field camp, among other activities.
Before passing out from BMT, NSFs have to complete a 24 km (14.91 mi) route march in Full Battle Order and attend the Passing Out Parade, which may be held at the Marina Bay Floating Platform.
After completing BMT, NSFs will receive their posting orders to their respective vocations, which are determined by their PES status, suitability for deployment, and manpower requirements, among other conditions. Some NSFs will be directly posted to a military unit while others may undergo vocational training at certain institutes before being posted to units.
NSFs who perform well during BMT may progress to either the Specialist Cadet School or Officer Cadet School for further training to become Specialists (non-commissioned officers) or Officers.
NSFs will serve the remaining part of their NS in their respective units until their Operationally-Ready Date (ORD), whereupon they will be known as Operationally-Ready National Serviceman (NSmen) or reservists. NSmen may still be required to take the IPPT every year and attend In-Camp Training of up to 40 days per year over a period of ten years, or until they are statutorily discharged from NS at the age of 40 (for Warrant Officers, Specialists and Enlistees) or 50 (for Officers).

Sri Lanka: In Sri Lanka, officer training is carried out at the General Sir John Kotelawala Defence University and at the respective Military Academies of each respective service.

Basic training for new recruits of the Sri Lanka Navy which is approximately six months are conducted at  Advanced Naval Training Center, SLNS 'Nipuna'; Naval Artificer Training Institute, SLNS 'Thakshila', Welisara; and at Naval Recruit Training Centres at several shore establishments . This basic training will be followed by on-the-job training on-board fleet units and at shore establishments. Combat Training School at SLNS 'Pandukabaya' conducts combat training for Naval Patrolmen.
Basic training for airmen of the Sri Lanka Air Force is handled by the Training Wing of the SLAF Diyatalawa. This is followed by secularized training at  Advanced & Specialized Trade Training School.

Sweden: Since conscription ended in Sweden in 2010 (reintroduced in 2017), all recruits who seek employment within the Swedish Armed Forces have to go through Grundläggande Militär Utbildning (GMU) (Basic Military Training) for three months.
Since conscription was reintroduced in 2017, all recruits who seek employment in the Swedish Armed Forces have to go through Grundutbildning (GU) (Basic Training), which consists of two parts; Grundläggande Militär Utbildning  (GMU) (Basic Military Training) that lasts for 3 months and aims to provide every recruit with the same foundation for continued military service, and Befattningsutbildning (Specialization Education) for between 1–11 months depending on specialization.
There is also a shorter volunteer training program for people who seek service within the Home Guard called GU-F. GU-F training takes only 14 days, but following a completed GU-F, a guardsman may go through additional training in order to specialize within the Home Guard.
Basic training as part of GU as well as GU-F usually takes place at any of the Swedish Army training units.

Switzerland: Switzerland has mandatory military service (German: Militärdienst; French: service militaire; Italian: servizio militare) in the Swiss Army for all able-bodied male citizens, who are conscripted when they reach the age of majority, though women may volunteer for any position. Conscripts make up the majority of the manpower in the Swiss Armed Forces.
At the age of 19, all male Swiss nationals must attend the two-day recruitment process in one of the six recruitment centres spread across Switzerland (Aarau, Payerne, Sumiswald, Monte Ceneri, Rüti, Mels). At the end of those two-days, if fit for service, recruits are assigned to a position in the Swiss Armed Forces.
A few months later, recruits start an 18-week (23-week for special forces) boot camp (German: Rekrutenschulen; French: école de recrues; Italian: scuola reclute) during which they are allowed to go home on week-ends. There are two boot camp start per year : January (Winter) and June (Summer). During the recruitment process, recruits can choose whether they would like to serve during summer or winter.
In the first seven weeks of boot camp, recruits receive "General Basic Instruction" (German: Allgemeine Grundausbildung; French: Instruction de base générale; Italian: Istruzione di base generale). During this period, recruits are instructed by their sergeants to military tactics, the use of weaponry (including SIG SG 550) and other equipment, marksmanship, self-defense skills, buddy- and self- aid, CBRN defense, basic survival skills, etc. Recruits are also educated to military life, including how to speak to their superiors, how to clean their weapons and combat shoes, how to clean the barracks, etc. During this period, recruits practice sport on a daily basis, including foot drill, running, team sports, push-ups, etc., and a few kilometers' march (up to 50 km) for some weeks.
The second phase of six weeks is devoted to function-specific basic instructions (German: Funktionsgrundausbildung; French: Instruction de base spécifique à la fonction; Italian: Istruzione di base alla funzione), where recruits learn skills specific to their job.
In the third phase, called "instruction in formation" (German: Verbandsausbildung; French: Instruction en formation; Italian: Istruzione di reparto), battlegroups and battalions are formed.

United Kingdom: British armed forces recruits train in two phases. The length of Phase 1 recruit training varies according to service and trade. The British Army Phase 1 training, for all enlisted units other than infantry, lasts 14 weeks. Infantry units of the British Army undergo a combined 28 weeks basic training, with the exception of the Parachute Regiment (30 weeks), Guards Regiments (30 weeks) and the Royal Gurkha Rifles (36 weeks).
The Royal Air Force provides 10 weeks of basic training for all enlisted recruits, regardless of trade, and is delivered at RAF Halton.
The Royal Navy provides 10 weeks of basic recruit training for all enlisted recruits, with the exception of the Royal Marines, delivered at HMS Raleigh. The Royal Marines (excluding the Royal Marines band), undertake 32 weeks of basic training, delivered at Commando Training Centre Royal Marines.
Phase One is initial recruit training designed to bring all recruits to a similar standard of basic military ability. Upon completion of Phase 1 training, recruits (with the exception of Army infantry roles, and the Royal Marine Commandos) will progress to their trade specific Phase Two training, which consists of courses of varying duration to prepare recruits for their assigned role.
Officer recruits into the UK Armed Forces undergo the following Basic training:

British Army - 44 weeks, delivered at Royal Military Academy (RMA) in Sandhurst.
Royal Air Force - 24 weeks, delivered at RAF College Cranwell (MIOTC).
Royal Navy - 30 weeks (split into two equal phases of 15 weeks each), delivered at Britannia Royal Naval College (BRNC) in Dartmouth.
Royal Marines - 15 months, delivered at Commando Training Centre Royal Marines, with 3 weeks towards the end of the course in the United States.
Upon completion of their Officer recruit training, cadets will then progress to their trade specific training of varying length.
The British Army, Royal Navy, Royal Marines and Royal Air Force manage their own Phase One and Phase Two training establishments.

United States: In the United States, recruit training in the U.S. Army is called Basic Combat Training (BCT); U.S. Army Combat Arms MOS (11 Series, 19 series, 13 series, 12 series) and Military Police MOS (31 series) undergo One Station Unit Training (OSUT) which involves BCT, Advanced Individual Training (AIT) and Specialized Training (such as Bradley, or Mortar School, or Gunnery) all in one. In the U.S. Air and Space Forces it is called Basic Military Training (BMT). In the U.S. Navy, U.S.
