While Portuguese forces had all but won the guerrilla war in Angola, and had stalemated FRELIMO in Mozambique, colonial forces were forced on the defensive in Guinea, where PAIGC forces had carved out a large area of the rural countryside under effective insurgent control, using Soviet-supplied AA cannon and ground-to-air missiles to protect their encampments from attack by Portuguese air assets. Overall, the increasing success of Portuguese counterinsurgency operations and the inability or unwillingness of guerrilla forces to destroy the economy of Portugal's African territories was seen as a victory for the Portuguese government policies.
