The mainly Shia Muslim Sixth Brigade had been commanded by a Christian officer, Colonel Lufti Jabar, and consisted of 1,600 soldiers and officers. Its mission had been to maintain order in West Beirut. It refused to participate in the February 1986 combat between the Shia Amal militia and the Lebanese Army, however; as a result, the Fifth Brigade was expelled from West Beirut. After the Sixth Brigade split off from the army command structure, it was taken over by a new officer, Major General Abd al Halim Kanj, and its ranks swelled to 6,000 men as Muslims from other army brigades deserted to join their coreligionists. In 1987 the Sixth Brigade was stationed in Shihab barracks in the southern suburbs of Beirut and was under the operational control of the Amal militia.
