The discipline and organizational abilities displayed by the MoC at the opening months of the civil war, allowed the movement to engage in the formation of the Christian rightist parties and militias alliance that eventually would become in January 1976 the Lebanese Front. Conversely, its 200-strong "Tanzim" militia, led jointly by Fawzi Mahfouz and Obad Zouein, saw the heaviest street fighting ever in East Beirut, including the Battle of the Hotels and the sieges of Karantina and Tel al-Zaatar. At the later battle they reportedly contributed with 200 militiamen, allegedly Lebanese Army soldiers in disguise.
