The brigade also fielded a logistics battalion, equipped with US M151A2 jeeps, Land-Rover long wheelbase series III, Chevrolet C20 and Dodge Ram (1st generation) pickups and US M35A2 2½-ton military trucks.

During the Mountain War in early September 1983, 7th Brigade's units were deployed at Achrafieh and Hadath in Beirut, and at Dahr al-Wahsh facing Aley in the Chouf District southeast of the Lebanese Capital, where they faced the offensive of the main anti-government Druze militia, the People's Liberation Army (PLA) of the Progressive Socialist Party (PSP).

[10] The brigade's 72nd battalion positioned at Dahr al-Wahsh was driven out from the Chouf by the Druze PSP/PLA militia and forced to withdraw to East Beirut in February 1984.

Units at Amsheet were well equipped with US-made M48 tanks and M113 armored personnel carriers but were regarded as being under the sway of Lebanese Forces militia' Supreme Commander Samir Geagea, who maintained there his retinue.

[16] During General Michel Aoun's Liberation War in 1989-1990, the 7th Brigade led by Colonel Sami Rihana put a spirited defense of Madfoun and Kfar Abida in the Batroun District on 13-14 August 1989, inflicting heavy losses on attacking Syrian Army armored columns and later on September 13, the brigade's units positioned at Mneitra were subjected to heavy mortar fire by the Syrians.
