The British troops were withdrawn by 24 March 1956, but soon afterwards, the Suez Crisis arose, known in Egypt and the Arab World as the "Tripartite Aggression." Just before the Suez Crisis, politics rather than military competence was the main criterion for promotion. The Egyptian commander, Field Marshal Abdel Hakim Amer, was a purely political appointee who owed his position to his close friendship with Nasser. A heavy drinker, he would prove himself grossly incompetent as a general during the Crisis. Rigid lines between officers and men in the Egyptian Army led to a mutual "mistrust and contempt" between officers and the men who served under them. Egyptian troops were excellent in defensive operations, but had little capacity for offensive operations, owing to the lack of "rapport and effective small-unit leadership".
