Tannous, who is close to President Gemayel, resigned his post as armed forces commander in June 1984 as a concession to government's opposition factions who were calling for restructuring the army and was succeeded by Michel Aoun.Until Gen. Tannous' resignation, the army was one of the most important institution supporting the U.S.-backed Gemayel Government, however, Tannous' departure marked a major shift in the American-trained armed forces towards a policy closely in tune with Syria's foreign policy and security objectives.
