Recruitment

The DSI recruits its future operators directly within the superior schools of the national gendarmerie for officers (the latter are selected before their graduation) and at the level of the schools of non-commissioned officers of the national gendarmerie of Sétif and Sidi Bel Abbès for non-commissioned officers.[4]

Induction training

The students wishing to join the unit are first evaluated, if they pass this evaluation phase, they will be admitted to the integration program which has 4 phases :[4]

• The physical preparation program: (Military training, instruction in combat sports such as karate, boxing, unarmed combat, armed combat, martial arts in general...). They are supervised by professional instructors from the combat sports unit.
• The blocked training course of preparation: (Physical, psychological, and combat training) this phase is one of the most difficult because the trainee is put to hard test (day and night exercise, unfavorable climatic conditions...) and it ends with the famous psychological obstacle course.
• The qualification parachute jump: They go through the School of commando training and initiation to parachuting (EFCIP) of Boghar in order to pass their parachutist license, but also to be initiated to commando techniques and parachuting.
• The special intervention professional patent (BPSI): This is the final training to be operational within the unit, the trainees will receive courses in diving, combat first aid, training for dog handlers, but also shooting, use of explosives, close protection, and techniques of climbing buildings and reliefs, intervention in closed environment (Close Quarter Battle), open, etc...), are on the menu of these daily sessions. The training is carried out in 2 stages, the first is the phase of pedagogical instruction, and the second is the phase of restitution and evaluation of the trainees, they must pass the final test if they want to integrate the unit.

The duration of training in DSI is 6 months, and trainees receive the equivalent of 1400 hours of advanced training.

Continuous training

Nevertheless, the operators are in almost permanent training and each member follows a daily training. Shooting training is daily, with each element able to go to the shooting range whenever they wish.

Shooting tests including timed, selective shooting, accuracy, long range, are evaluated by the training cell instructors. The training operations of different scenarios, always with live ammunition, are reviewed and debriefed to correct each action and try to improve its technicality. They also often train at night under night vision binoculars on all types of situations in the 13 sites reserved for them. exercises from a helicopter with recall techniques but also on fast driving and basic techniques in the field of negotiations and hostage taking.
