'They are swift, silent and almost invisible in the long elephant grass. With rifles at the ready and wearing camouflage uniforms that blend with the bush at 10 paces, these are the men waging Rhodesia's secret was against African terrorists.' Rhodesia, a former British colony, became officially independent in 1979 and was re-named Zimbabwe.
