Volunteers and conscripts receive 14 weeks of basic training in military skills and discipline. This is followed by more advanced training in weaponry and various specialities, such as artillery, communications and engineering, after the recruit is assigned to a permanent unit. Soldiers who qualify for promotion undertake courses at a general NCO school. They may then avail themselves of courses in more specialised centres where there is training in armour, artillery, engineering and logistics. Special Forces personnel are trained in a branch of the infantry school.
