Since 1946, it has played a major role in Syria's governance, mounting six military coups: two in 1949, including the March 1949 Syrian coup d'état and the August 1949 coup by Colonel Sami al-Hinnawi, and one each in 1954, 1963, 1966, and 1970. It has fought four wars with Israel (1948, the Six-Day War in 1967, the October War of 1973, and 1982 in Lebanon) and one with Jordan (Black September in Jordan, 1970). An armored division was also deployed to Saudi Arabia in 1990–91 during the Persian Gulf War, but saw little action. From 1976 to 2005 it was the major pillar of the Syrian occupation of Lebanon. Internally, it played a major part in suppressing the 1979–82 Islamist uprising in Syria, and since early 2011 has been heavily engaged in fighting the Syrian Civil War, the most violent and prolonged war the Syrian Army has taken part in since its establishment in the 1940s.
