During his military service, he progressed from an infantry
platoon leader to a
Battalion Commander, and then assumed the position of a trainer in the Military Academy and in the
non-commissioned officer School. From 25 December 1990 until 21 August 1991 he was appointed as the Chief of the Intelligence Branch of
Mount Lebanon. The Lebanese Army Intelligence of Mount Lebanon was after the detention of hundreds of anti-Syrian demonstrators with some cases of reported torture. On 25 August 1991 he was reassigned to the post of the Army Staff Secretary-General until 10 June 1993. He was commander of the 11th Infantry Brigade from 6 June 1993 to 15 January 1996, a period that witnessed violent confrontations with the
Israeli forces in the West
Beqaa Valley and South Lebanon regions. On 15 January 1996 he was appointed as commander of the 6th Infantry Brigade and remained in this position until 21 December 1998, when he was appointed as the commander of the Armed Forces. His appointment was reported to be a result of his family relations with a Syrian high-level official. On 7 May 2008, an ongoing political crisis between government loyalists and the opposition
quickly spiraled out of control when
Hezbollah announced that the government's decisions to declare the group's private telecommunications network as illegal and to relieve the head of security at
Beirut International Airport (an alleged
Hezbollah sympathizer) of his duties amounted to a "declaration of war". Fighting immediately broke out throughout the country, with members of Hezbollah and its allies in the
Amal Movement and the
Syrian Social Nationalist Party quickly bearing down on their enemies in the
Future Movement and the
Progressive Socialist Party. The fighting lasted until 14 May 2008, when the Lebanese government canceled its two decisions after the proposition of Suleiman to do so. As the crisis ended, Suleiman was the subject of criticism by some commentators and politicians since the Army did not directly intervene in the armed clashes that took place but instead tried to separate between fighters and protected political figures. On the other hand, others defended his stance by arguing that the only way to preserve the Army's unity and prevent another civil war was to ensure that it remained uninvolved in the fighting against the Lebanese citizens.
