By 1977 the war had spread throughout Rhodesia. The ZANLA continued to operate from Mozambique and remained dominant among the Mashona peoples in eastern and central Rhodesia. Meanwhile ZIPRA remained active in the north and west, using bases in Zambia and Botswana, and were mainly supported by the Ndebele tribes. With this escalation came increasing sophistication and organisation. No longer were the guerrillas the disorganized force they had been in the 1960s. Indeed now they were well-equipped with modern weapons, and although many were still untrained, an increasing number had received training in Communist bloc and other sympathetic countries.
