During the 1980s, most of the army's combat units were concentrated in the 2nd Military Region (Oran) and to a lesser extent in the 3rd Military Region (Béchar). Chadli Bendjedid became head of the 2nd Military Region in 1964. Adjacent to Morocco, the 3rd Military Region straddles the main access routes from that country. It is also near the troubled Western Sahara, embracing territory previously claimed by Morocco. Much of the internal disorder and violence associated with economic distress and the Islamist movement has occurred in the 1st Military Region (Blida), which includes the capital of Algiers, and the 5th Military Region (Constantine). Army units have been strengthened in and near the cities where attacks against the government and security forces have occurred. Although regional commanders were originally all colonels, the commanders of the 1st Military Region (Mohamed Djenouhat) and the 5th Military Region (Abdelhamid Djouadi) were both promoted to major general in 1992. The two southeastern jurisdictions — the 4th Military Region (Ouargla) and 6th Military Region (Tamanrasset) — were sparsely populated tracts of desert where a limited number of combat troops carried out patrols and manned small outposts. The Ouargla region assumed a measure of strategic importance after relations with Libya soured, but the military's main activities there and in the 6th Military Region are the construction and planting projects undertaken by conscript forces. The 6th Military Region was created in 1975 to cover the south.
