Saqr and his militia participated in the Lebanese Civil War in the 1970s and 1980s, and remained militantly active until he was expelled from the country with the flight of the South Lebanon Army, of which he was not a member, in May 2000.

Saqr joined the Sûreté générale (General Security Directorate) in 1954 and was involved in fighting against pan-Arab forces in the Lebanon crisis of 1958.

Worth noting is the pan-Lebanese conception of the party whose members were drawn not only from Christian circles but Muslim and Druze as well.

Saqr withdrew from the Front and the Guardians retreated to the mountains but continued to fight on the LF side in key battles, including East Beirut (1978) and Zahlé (1981).

Saqr was sentenced to seven years hard labour for collaborating with Israel but escaped to Jezzine in the Israeli security zone.
