中国人民解放军第二炮兵部队
At the start of the civil war, Aoun was the commander of the Second Artillery Corps of the Army. He took part in the Battle of Tel al-Zaatar, claiming that he developed and planned the siege of the camp and its storming. He directed the attack, which resulted in destruction of it, and the Palestinian refugees being displaced. In 1978, he went to France again for more military training at École Supérieure de Guerre.
