Basic training
Major characteristics: Initial military training is an intensive residential programme commonly lasting several weeks or months, which aims to induct newly recruited military personnel into the social norms and essential tasks of the armed forces. Common features include foot drill, inspections, physical training, weapons training, and a graduation parade.
The training process resocializes recruits to the demands made of them by military life. Psychological conditioning techniques are used to shape attitudes and behaviours, so that recruits will obey all orders, face mortal danger, and kill their opponents in battle. According to an expert in United States military training methods, Dave Grossman, recruit training makes extensive use of four types of conditioning techniques: role modeling, classical conditioning, operant conditioning, and brutalization.
Inductees are required to partially submerge their individuality for the sake of their military unit, which enhances obedience to orders to perform actions normally absent from civilian life, including killing and prolonged exposure to danger.
The resocialization of recruit training operates in several ways, as follows:

Confinement and suppression: Once their training has begun, the right of recruits to leave the military estate (or to quit the armed forces) is denied or tightly restricted. By shaving the head, issuing uniforms, denying privacy, and prohibiting the use of first names, individuality is suppressed.

Control and conformity: Recruits' daily routine is highly controlled, in the manner of the 'total institution' described by the Canadian-American sociologist Erving Goffman. For example, the training regime determines how recruits must make their beds, polish boots, and stack their clothes; mistakes are punished.

Throughout their training, recruits are conditioned to conform to military norms and to work as a team. In particular, recruits are repeatedly instructed to stand, march, and respond to orders in a ritual known as foot drill, which is derived from 18th-century military practices and trains recruits to obey orders without hesitation or question. According to Finnish Army regulations, for example, foot drill is essential for the esprit de corps and cohesion, accustoms recruits to instinctive obedience, enables large units to be marched and moved in an orderly manner, and creates the basis for action in the battlefield.

Stress and punishment: The training process applies stressors continuously. Instructors may deprive recruits of sleep, food, or shelter; shout personal insults; use physical aggression; or give orders intended to humiliate. According to specialists in U.S. recruit training, the conditions of continuous stress deplete recruits' resistance to the demands made of them.

The intense workload and sleep restriction experienced by military recruits leaves them little attention capacity for processing the messages they receive about new norms… Therefore, recruits should be less likely to devote their remaining cognitive effort to judging the quality of persuasive messages and will be more likely to be persuaded by the messages…
Evidence from Canada, the UK, the U.S. and elsewhere shows that punishments are used routinely to condition group conformity and discourage poor performance. The role of group punishment in Canadian Army training, for example, has been described as follows:

Coming from civilian society that elevates the individual, recruits are now in a world where the institutional value of the group is supreme. One has to be a team player or risk ostracism. The military does things quite deliberately to intensify the power of group pressure within its ranks. The group is made responsible for each member... even though it may seem manifestly unfair to make the group suffer for the individual.

Bonding and the hierarchy of esteem: As a buffer against the stressful conditions of their training, the trainee group normally forms a strong bond of mutual loyalty. Researchers in the U.S. have described it as an intense "we-feeling", which can feel more powerful than the civilian bonds that recruits are familiar with. In 2006, an official report on Australian Defence Force training explained the importance of the group bond:

Willingness to apply lethal force requires… sufficient bonding within the team to override each individual’s natural human resistance to kill. The toughness and bonding required increases the closer the contact with the enemy.
Recruits are taught to be proud of their identity as professional military personnel, and of their unit in particular. Heroic regimental stories and symbols are used to ennoble the recruits' own unit above others, and above other branches of the armed forces (an aspect of Interservice rivalry), thereby establishing a hierarchy of esteem (also known as a hierarchy of respect); the same stories are used to draw a contrast with the purported inferior norms associated with civilian life. (Cf. Unit cohesion)

Aggression and objectification: Evidence from Australia, the UK and the U.S. shows that recruit training systematically stimulates aggression, particularly in those enlisted for ground close combat roles. Bayonet practice is an example, as the strong language of this instruction from a British army corporal illustrates:

I wanna see it in your eyes that you wanna kill these fuckers. Imagine these dummies are the fucking Taliban and they’ve just killed some of your mates. You wanna fuckin’ kill them. Show me your war face! [Recruits yell] You need some fucking more aggression, show me your war face.
Another example is milling, an exercise used for infantry training in which pairs of recruits wearing boxing gloves punch each other in the head as aggressively as possible.
To further enable recruits to kill on demand, they are taught to objectify (dehumanize) their opponent in battle as an ‘enemy target’ to ‘be engaged’, which will ‘fall when hit’.

Fieldcraft and fitness: Recruits are taught the basic skills of their profession, such as military tactics, first aid, managing their affairs in the field, and the use of weaponry and other equipment.
Throughout, the physical fitness of recruits is tested and developed, although evidence from Israel, Norway, South Africa, the UK and the U.S. has found that the heavy strain on the body also leads to a high rate of injury.

Graduation and drop-out: Recruits who complete their initial training normally take part in a graduation parade (also called passing-out or marching-out). The parade is observed by their family and friends, and senior military personnel. Recruits then pass to the next stage of their training, if applicable.

A large percentage of recruits drop out of training. For example, attrition among British infantry recruits has been found to be above 30% during the first 12 weeks. Reasons for this include dismissal for behavioural problems, poor performance, or injury, and furthermore, recruits who choose to leave if and when they have a legal right to do so. In the UK and U.S., recruits under the age of 20 are most likely to drop out in these ways.

Variations in recruit training: Recruit training varies by nation according to the national requirement and can be voluntary (volunteer military) or mandatory (conscription). Some nations operate both volunteer and conscription systems simultaneously.
Recruit training differs according to military branch:

Army and Marine Corps recruits are normally trained in basic marksmanship with individually assigned weapons, field maintenance of weapons, physical fitness training, first aid, and basic survival and infantry techniques.
Navy and Coast Guard training usually focuses on water survival training, physical fitness, basic seamanship, and such skills as shipboard firefighting, basic engineering, and signals.
Air Force and Space Force training usually includes physical fitness training, military and classroom instructions, basic airmanship/guardianship and field training in basic marksmanship and first aid.

Australia: Most of the recruit training in the Australian Army is currently held at Army Recruit Training Centre (ARTC) at Kapooka, near Wagga Wagga in New South Wales. Recruit training lasts 80 days for members of the Australian Regular Army and 35 days for members of the Australian Army Reserve. In basic training recruits are taught drill, weapons and workplace safety, basic equipment maintenance, marksmanship, fieldcraft, radio use and defensive/offensive operations.

Regional Force Surveillance Units: Training for recruits in the Regional Force Surveillance Units usually differs greatly from training in the rest of the Army. For instance, NORFORCE recruits attend a 2-week course at the Kangaroo Flats. Recruits from areas covered by the RFSUs often come from indigenous cultures radically different from that of the general Australian population, and as such many regular standards and methods of training are not as applicable in their case.

Royal Military College Duntroon: Recruit Training for officers in the Australian Army (known as ICT—Initial Cadet Training) takes place at Royal Military College, Duntroon (RMC). The ICT is conducted for approximately seven weeks after which staff cadets continue military instruction in skills such as weapons training, military history, leadership, strategic studies and other such skills at section, platoon and company levels. Trainees at RMC hold the rank of Staff Cadet and, if successful in completing the course are commissioned as Lieutenants (pronounced Left-tenant). The overall full-time officer training course at RMC is 18 months long.

Canada: Centralized recruit training in the Canadian Army did not exist until 1940, and until the creation of Basic Training Centres across Canada, recruit training had been done by individual units or depots.
In 1968 the Canadian Army, Royal Canadian Navy, and Royal Canadian Air Force were unified into one service, the Canadian Forces. The Canadian Forces Training System, a unified system for all the services, was devised and remains in place today.
Most non-commissioned CF recruits in the Regular Force (full-time) participate in the 8-week Basic Military Qualification (BMQ) at Canadian Forces Leadership and Recruit School at Saint-Jean-sur-Richelieu, Quebec.
