1977 the army fought in the Libyan-Egyptian War. By early July 1977, the two divisions deployed to the Egypt-Libya border had been raised to full strength and were dug in. They were bolstered by several Sa'ka Forces commando battalions and support units, while a third division stationed near Cairo and other commandos were ready to relocate on short notice. A total of over 40,000 troops were deployed to the border during the war. The army had an estimated strength of 320,000 in 1989. About 180,000 of these were conscripts. Beyond the Second Army and Third Army in the east, most of the remaining troops were stationed in the Nile Delta region, around the upper Nile, and along the Libyan border. These troops were organised into eight military districts, later reduced to five major regions. Commando and airborne units were stationed near Cairo under central control but could be transferred quickly to one of the field armies if needed. District commanders, who generally held the rank of major general, maintained liaison with governors and other civil authorities on matters of domestic security. Decision making in the army continued to be highly centralized during the 1980s. Officers below brigade level rarely made tactical decisions and required the approval of higher-ranking authorities before they modified any operations. Senior army officers were aware of this situation and began taking steps to encourage initiative at the lower levels of command. A shortage of well-trained enlisted personnel became a serious problem for the army as it adopted increasingly complex weapons systems. Observers estimated in 1986 that 75 percent of all conscripts were illiterate when they entered the military. 1990s and after Since the 1980s the army has built closer and closer ties with the United States, as evidenced in the bi-annual Operation Bright Star exercises. This cooperation eased integration of the Egyptian Army into the Gulf War coalition of 1990–91, during which the Egyptian II Corps under Major General Salah Halabi, with 3rd Mechanized Division and 4th Armoured Division, fought as part of the Arab Joint Forces Command North. The deployed force performed appallingly. It was unable to move up the first attack time after a request from overall commander U.S. General Norman Schwarzkopf; halted after 'desultory' Iraqi artillery fire; continued to move so slowly that on the morning of the third day of the war, still had not taken their first day's objectives; and could
