Between 1948 and 1967, a series of military coups destroyed the stability of the government and any remaining professionalism within the army. In March 1949, the chief of staff, General Husni al-Za'im, installed himself as president. Two more military dictators followed by December 1949. General Adib Shishakli then held power until deposed in the 1954 Syrian coup d'etat. Further coups followed, each attended by a purge of the officer corps to remove supporters of the losers from the force. 'Discipline in the army broke down across the board as units and their commanders pledged their allegiance to different groups and parties. Indeed, by the late 1950s, the situation had become so bad that Syrian officers regularly disobeyed the orders of superiors who belonged to different ethnic or political groups' writes Pollack. The 1963 Syrian coup d'état had as one of its key objectives the seizure of the Al-Kiswah military camp, home to the 70th Armored Brigade. There was another 1966 Syrian coup d'etat.
