The Soviet Union invested heavily in bolstering the mechanized and armoured capabilities of the People's Armed Forces of Liberation of Angola (FAPLA) during the Angolan Civil War. To that end, it provided FAPLA with just under 500 BTR-60s as part of a comprehensive military assistance programme between 1975 and 1989. FAPLA initially received 74 BTR-60PBs in 1975, and ordered another 175 BTR-60PBs in 1980, which were delivered between 1981 and 1985. In 1987 and 1988, Angolan motorized brigades received another 250 BTR-60PBs and some BTR-60R-145BM command vehicles.
