By early 1978, militant victories put the Rhodesian armed forces on the defensive. The government abandoned its early strategy of trying to defend the borders in favour of trying to defend key economic areas and lines of communication with South Africa, while the rest of the countryside became a patchwork of "no-go areas." Rhodesia's front-line forces never contained more than 25,000 troops, eight tanks (Polish made T-55s) and nine old Hawker Hunter jets. Those forces could still launch raids on enemy bases, but Rhodesia faced diplomatic isolation, economic collapse and military defeat.
