[12] Lebanese Air Force Hawker Hunter jets flew their last combat sortie over the Chouf, carrying out air strikes against advancing Druze PLA forces on the western portion of the Shahhar region in support of the Fourth Brigade's units reinforced by the 101st Ranger Battalion from the 10th Airmobile Brigade[14] fighting desperately to retain their positions at Aabey, Kfar Matta, Ain Ksour, and Al-Bennay, which achieved little success due to poor planning and lack of coordination with Lebanese Army units fighting on the ground.

[12] Surrounded and badly mauled, the brigade disintegrated when approximately 900 Druze enlisted men, plus 60 officers and NCOs, deserted to join their coreligionists of Jumblatt's PLA or Syrian Social Nationalist Party (SSNP) militias.

[12][15] The remainder 1,000 or so Maronite Christian Officers' and men either withdrew to the coast, regrouping at the Damour – Es-Saadiyat area or fled south across the Awali River, seeking protection behind Israeli lines while leaving behind some US-made Tanks and APCs, Jeeps, trucks, Howitzers, and ammunition.

The SLA, LF, Amal and the PSP/PLA also seized all the defunct brigade's liaison and transport vehicles, which the latter three militias turned into technicals by re-arming them with heavy machine guns, recoilless rifles and anti-aircraft autocannons.

Nevertheless, on a meeting held on 28 June that same year, the LAF Military Council decided to reform the Fourth Brigade but, due to political constraints, such plans were put on hold for the duration of the War.
