The Eleventh Brigade, composed primarily of Druzes, had a strength in 1987 of about 900 men. Its commander, Colonel Amin Qadi, ordered the unit confined to its Hammana garrison during the fighting between the Lebanese Army and the Druze militia in the Shuf in 1983 Mountains and 1984; this action was in response to a request from Druze leader Walid Jumblatt to neutralize the army. The Eleventh Brigade controlled the Hammana garrison and guarded the government radio station in West Beirut.
Little was known in 1987 about the mostly Shia 1,300-man strong Twelfth Brigade. It was commanded by Colonel Muhammad Saad and was deployed in various positions in southern Lebanon, particularly along the coastal highway between Khaldah and Sidon.
