[3] In July 1945 a French-Lebanese military agreement was signed, officially signalling the disbandment of the TSL, broken up to form the new Lebanese and Syrian national armies.

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 (6x6) military trucks.

[14] On February 6, 1984, the LAF Command of the Greater Beirut area decided to send the 52nd Infantry Battalion in M113 APCs supported by a Tank squadron provided with M48A5 MBTs on a routine patrol mission, whose planned route was to pass through the Dora suburb, the Museum crossing in the Corniche el Mazraa, the Barbir Hospital in the Ouza'i district, the Kola bridge, and the Raouché seafront residential and commercial neighbourhood.

An alarmed Amal Command promptly issued a general mobilization order in the ranks of its militia, and as soon as the Lebanese Army patrol arrived at the Fouad Chehab bridge near the Barbir Hospital, they fell into an ambush.

In 1987 Fifth brigade units were deployed to the strategic town of Souk El Gharb to prevent Druze artillerymen of the People's Liberation Army (PLA) militia from shelling the capital.
