The brigade also fielded a logistics support battalion, equipped with liaison and transport vehicles such as US M151A2 jeeps, Land-Rover long wheelbase series III, Chevrolet C20 and Dodge Ram (1st generation) pickups, plus US M35A2 2½-ton (6x6) military trucks.

[7] On February 13, 1984, the 101st Ranger Battalion was rushed to the western portion of the Shahhar region to reinforce the beleaguered units of the 4th Brigade, who were fighting desperately to retain their positions at Aabey, Kfar Matta, Ain Ksour, and Al-Beniyeh while sustaining a wave of ground assaults by the Druze People's Liberation Army (PLA) militia led by Walid Jumblatt.

The militias' ground offensive was preceded by a massive and sustained Syrian artillery barrage on the positions held by Aounist troops, who repulsed the assault by inflicting some 20-30 casualties on the PSP/PLA attackers.
