The Force 75, also designated the 75th Battalion or 75th Brigade, was the personal militia of Amine Gemayel, Bashir Gemayel's elder brother. Technically a territorial unit of the Kataeb Regulatory Forces, the Force 75 usually operated in the north of the Matn District, where it was primarily based, though they also fought at East Beirut, participating in the final phase of the Tel al-Zaatar battle on July–August 1976.
